Asumu (明日夢 Asumu) was a young boy that lived during the Sengoku Period. He helped gathering Oni to defeat the Makamou Orochi. Asumu was also one of the founders of the organisation Takeshi.

Personality and background

Asumu SP 01

He and his brother Takeshi lost their parents at an early age and Tobee came to view them as his sons. Asumu became friends with Hitoe and Suzu who lived in the same village. His brother eventually became an apprentice to the Oni Hibiki. However, on a rainy day, Hibiki came carrying Takeshi's lifeless body. Asumu tried to shake his brother awake, and cried as he did. He then turned to anger and grabbed Hibiki by the collar and blamed him for his brother's death. Hibiki stood unmoving as Asumu hit him over and over. Asumu's village would at one point make a deal with the neighbouring Makamou, Orochi, which meant they would have to sacrifice a maiden each year to ensure their safety. Suzu was one day chosen to be the sacrifice, but Asumu did not like it, and disobeyed Tobee who had told them to stay away from the beach where the sacrifice took place.


Asumu SP 02

Asumu ran to the beach, but he was followed by Hitoe who reminded him that they had been warned to stay away by Tobee as it was dangerous. They peered through some shrubbery at an overlook down at the beach where Tobee was leading the procession. Suzu was being carried in a box by the men of the village to a sacrificial altar. Tobee stopped the procession and asked Buddha if it was really okay to sacrifice her. A large castle suddenly surfaced out in the ocean and two voices asked for the sacrifice to be provided. Suzu's parents panicked and ran to her side, but she tried to tell them that it was for the best and then ran to the sacrificial altar. She sat down and waited as the Orochi appeared, but her father told her to stop and ran to her. The Douji and Hime flew at him as fox-fires and struck him down without mercy. The Orochi then descended on Suzu and at her, leaving the villagers in despair. Hitoe asked why something like that could happen.

Asumu SP 03

After on year had passed, Asumu and Hitoe tended to Suzu's gravestone. Asumu said there was no meaning to the gravestone, but Hitoe protested as it was the only thing they could do. Both of them exclaimed that they wanted the sacrifice to stop, when suddenly Hitoe was marked with the demon kanji. Hitoe panicked and Asumu was horrified. In the evening, Asumu protested to the sacrifice to the village leaders, but Tobee said it was painful for him to. Tobee's daughter Hinako agreed with Asumu and remarked that Hitoe was only 15 years old. Her sister Kazue asked why they had to continue with the sacrifice. Tobee said there might be a way, and suggested they find the Oni that fought the Makamou in Japan. One of the leaders protested and said the Oni had given up their humanity and were now as untrustworthy as demons. More of the village leaders agreed, while Asumu started to reminisce of his brother Takeshi's death and how Hibiki had brought his lifeless body to Asumu. Asumu refused to ask the Oni for help, but Kazue said it was the only way. Hinako agreed as she had heard a lot of stories of Oni that saved people. Asumu told them to stop it and reminded them that it was an Oni's fault that Takeshi died. Asumu ran out of the meeting and went to Suzu's gravestone where he met Hitoe. She commended Suzu for giving herself up to save them, and she wondered if she would be able to do the same. She started to cry as she asked Asumu to not look at her when she was being killed. Hitoe was very scared and did not want to die.

Asumu SP 04

The talk with Hitoe made Asumu change his mind, so the next day he went with Hinako and Kazue to look for the Oni, despite the protests of the other village leaders. As they were walking, Asumu wondered how they were going to find the Oni. Kazue had heard of other villages being attacked by the Makamou and an Oni would certainly come to them. Hinako said they should try to go to one of those villages.

They soon came to a village called Tokyo where an Oni named Kabuki charged at a Makamou. Kabuki kept dodging the Kaendaishou's attack and transformed his Onsa to an Onsaken. They duelled for awhile until Kabuki buried it by collapsing a small roof on it and it turned to dust. The villagers thanked him and Kabuki told them the Makamou would not appear any more so they could relax. They were poor people and offered him some some sweet potatoes as thanks. Kabuki was annoyed but he then saw a hungry boy and asked if he wanted it.The boy nodded and ran up to get it, but his mother interrupted him and slapped the vegetable away, which surprised Asumu who was looking at them. The mother had forbidden her son to eat it as an Oni had touched it. Kabuki became gloomy from the incident, but Kazue stepped forward and asked for his help. Asumu looked suspiciously on him when Kabuki asked who they were. Kazue and Hinaka told him of how they need help with the Orochi, and Kabuki said it had been inevitable that he would have to fight it. But right now he could not defeat it. Suddenly the little boy from before appeared and Kabuki happily gave him the vegetable. He told him to eat it in secret so that his mother did not find out. He turned to them and said it was time for them to head of. Hinako asked to where and Kabuki flipped her on the forehead, asking if she did not want to defeat Orochi. Kazue asked what he meant, and he said that as he could not defeat it himself, there was no rush. He only needed to assemble some comrades as saving people was an Oni's duty after all.

Asumu SP 05

They headed to an old shack in a barren area and Kabuki informed them it was Hibiki who lived there. Asumu remarked on the name, and Kabuki said he was a little weird, but good and almost retired from being an Oni. He called out to Hibiki and just as he was about to open the door they were blasted backwards by a shock-wave. Hibiki came running out of the smoke and laughed as he said he had tried to make a new weapon but it failed. Asumu recognised him as his brother's teacher, whom he blamed for his brother's death. Asumu glared at him, but Hibiki did not recognise him and asked if there was something wrong. The boy ran away but Hinako, Kazue and Kabuki followed him. When they caught up to him they asked what was wrong, and he told them Hibiki was responsible for his brother's death. Kabuki said that Hibiki would not kill a human, but Asumu said it was true. Hibiki called for the boy and said he remembered him as Takeshi's little brother. He asked if he still held a grudge against him and said that such thinking was bad as it would be better to look forward. Asumu became furious and yelled at him to shut up and that he hated him. Kabuki held him back as the boy said he did not want any help from Hibiki. Hibiki asked what he was talking about and Kabuki explained he was gathering comrades to defeat Orochi. The Oni said there were plenty of Oni beside him, and he had quit already as it was a lot of trouble. He then went to fry some fish, while Asumu glared at him in anger.

Asumu SP 06

Kabuki led Asumu, Hinako and Kazue to a large town where they stopped for lunch. Asumu was still upset and was not eating, so Kabuki asked why. The boy said he did not want it, but Kabuki called it a waste and shoved it all into Asumu's mouth. Hinako asked if Kabuki was comforting the boy, but the Oni shrugged it of. He teased Asumu a little and the boy spit the food out on him, which made the sisters laugh. Asumu said it was enough as they needed to find more Oni. Kabuki told him to calm down as they were going to meet one soon. He led them through a busy street and pointed towards a large castle which was their destination. He said the one who lived there was the most prominent of the Oni., by helping in a war he became a Daimyō. They were granted an audience with him, and bowed their heads as he entered the room. The Daimyo known as Ibuki told them to not be so formal and to raise their heads. Kabuki laughed and asked what Ibuki was wearing. Ibuki was happy to see him, and Kabuki approached him while asking for his help as an Oni. Ibuki's retainers did not like it, and one got close to Kabuki and called him rude. Kabuki reacted by instinct and hit him which made the retainer call for the guards. Kabuki was about to face them when Ibuki told them to calm down. He confessed that he had become bored of the dull daimyo lifestyle, and in response cut of his hair. The retainers panicked as their lord was breaking tradition, so Ibuki beat the ones who tried to stop him. Ibuki dashed out from the castle together with Kabuki, Asumu, Hinako and Kazue while the retainers called out for their lord.

Asumu SP 07

Kabuki took them next to a temple shrine in Sapporo where a monk sat praying. Kabuki called him an idiot for always praying. Ibuki revealed that the monk was called Touki and had practised Buddhism before becoming an Oni, but Kabuki scoffed at the notion of Buddhism. Kabuki decided to test him and threw a large rock at the praying monk, but it was stopped mid-air and sent back at Kabuki who fell backwards. Touki stood up and asked if he saw his ability of the mind. If they trained, such a thing would be easy for them as well. He then said it was time to go and Kabuki asked where. Touki replied that he just had heard Buddha's voice saying it was the time for battle and that they were offering a girl to the Makamou.

Asumu SP 08

They thought they might have a chance to defeat Orochi now and asked Asumu and the women to take them to their village. When they arrived, Tobee agreed to switch Hitoe out with Ibuki in order to draw out the Douji and Hime. The villagers enacted the sacrifice procession and placed the Kago on the altar. Asumu and Hitoe was watching from above a cliff as the villagers left hastily when the castle appeared and the Douji and Hime asked for the sacrifice. The Douji and Hime flew to the altar and knocked the Kago apart, but when they removed the sacrifice's shroud, they were shocked to see it was Ibuki. The Oni told them Hitoe was not coming and that they should go to the afterlife. The Douji and Hime backed of as he transformed into his Oni form. Kabuki and Touki ran up to his side, and told the Makamou that they would defeat them. They transformed into their Oni forms and stared approaching the Douji and Hime. The Makamou became furious and uses their powers to cause explosions around the Oni. Asumu, Hitoe, Tobee and the villagers watches in despair as the Oni faced overwhelming powers. In the end, Touki used his blizzard technique which forced the Douji and Hime to retreat. The Orochi then attacked them and they were easily overpowered. Ibuki fired his Ongekikan at the Makamou but the Orochi was unphased and sent a fire blast at them which undid their transformations. They were forced to retreat which despaired the onlookers.

Asumu SP 09

The Douji and Hime summoned the village leaders and demanded to know why they had brought the Oni. The Makamou suspected they might be opposing them but one of the villagers said that they would never do such a thing. The villagers blamed the Oni for everything that happened. The Hime then said that Hitoe would get sick soon due to the mark, which upset Tobee. Asumu and Hitoe were hiding behind a few rocks when she started to feel the sickness. The Hime told the villagers to hand the girl to them in a month and if they broke the agreement again, the sickness would spread to all the villagers. The Douji told them to remember the agreement and their place. Hitoe became more in pain as the mark on her hand turned red.

The Oni and Asumu attended a village meeting with Tobee and the other leaders. The other leaders blamed Asumu for putting them in trouble as the Oni never had a chance in the first place. Kabuki asked what they meant and asked Asumu to say something to the leaders. Asumu said nothing and looked down on the floor which irritated Kabuki. The leaders told the Oni to get out as they would only bring them trouble now. They reluctantly agreed and left the village.

Asumu SP 10

Asumu followed Kabuki, Touki and Ibuki as they talked about how they had underestimated the Orochi. Kabuki stopped and asked if it really was okay to leave the villagers with the Makamou. Touki said that it could not be helped as they were lacking in power. Suddenly Kirameki came flying on a kite, and thanked them for waiting on him. He was enthusiastic to defeat some Makamou but Ibuki told him that they had already lost to it. It was a let-down for Kirameki who had been on his way as soon as he heard that Oni were gathering. He said they should try again as it would go well with him there. Kabuki agreed but Touki was opposed as Kirameki was a coward. Kirameki became nervous as Ibuki asked what Touki meant. The monk told him of how he had fought an Ittanmomen with him in the past, and Kirameki had run away in the middle of the battle. He tried to make an excuse so Touki asked why he never came back, but the Oni said he simply got lost. Kabuki got tired of their squabble and said it was enough, as it nevertheless was better that he was there with them now. Kirameki agreed and said they should gather more members. Kabuki exclaimed it was time to fight again.

Asumu SP 11

Asumu followed Kabuki, Ibuki, Touki and Kirameki to Nagoya where he accidentally bumped into several Rōnin who became angry and tossed him aside. A woman tried to stand up for Asumu but was hit as well. Just as they said they were going to skin Asumu, they were doused in water and Asumu got a bucket on his head. An unknown man challenged the Rōnin and easily defeated them. He disappeared before Asumu was able to get the bucket of his head, and the woman came back to see if he was alright.

Asumu SP 12

He lost track of the Oni and returned home in defeat. Eventually Kabuki came back with several more Oni such as Nishiki, Habataki and Todoroki. Asumu ran in to the communal house and was happy to see that they had returned. Kabuki was happy and said that they would be able to win this time with so many comrades. The village leaders continued to protest, but stopped when Kabuki, Kirameki and Touki glared at them. The villagers changed subject and headed out to find Hitoe and proceed with the sacrifice. The seven Oni were sitting in the community house in the evening when the villagers had lit fire to the house. The villagers yelled at them to come out which they did after breaking down the doors. Tobee tried to stop the villagers and yelled at them for what they had done. Asumu and Hinako watched as the house burned down.

Asumu SP 13

The next morning the house was all burnt down and the villagers had armed themselves against the Oni. Kabuki demanded to know why they had intended by burning them alive. One villager told him the Oni were killers, and several more agreed. Tobee stood in between and said the ones who lit the fire were the killers and demanded to know what the villagers meant. They revealed that several villagers had been attacked by an Oni, and Hitoe had seen it all. They also found a weapon at the scene and threw the Ongekitriangle on the ground. Ibuki recognised it as Nishiki's weapon, and the Oni did agree that it was his weapon. Asumu asked what was going on as Nishiki said someone had stolen his weapon. Nishiki would steal, but never kill people. The villagers called him a liar and said they were an enemy of the humans, just like the Makamou. Kirameki yelled at them when suddenly he was forced to deflect a bamboo spear. Another villager stabbed him in the leg, and the other villagers started attacking the Oni. Touki was stabbed, and Nishiki was cut which made him angry and he started to punch the attackers. Kabuki told him to stop and reminded him of their duty to not hurt humans. The villagers started throwing rocks at them while telling them to leave. Hinako and Tobee tried to stop the villagers, but Kirameki and Touki had had enough and were going to punish them. The villagers became frightened and Nishiki started approaching them in anger. The three were stopped by the other Oni, and Kabuki reminded them that they were not allowed to hurt the humans. All seven Oni transformed and started attacking each other. Asumu was trying to tell them to stop fighting, but it fell on deaf ears. Suddenly Hibiki came riding on a horse and rode straight into the fight, blocking everyone. He wondered what was wrong with them and jokingly said he got lost on a walk and ended up there. Hibiki greeted Asumu when he saw the boy. Kazue suddenly came running and told Asumu that Hitoe's condition was getting worse.

Asumu SP 14

The mark on Hitoe's hand had grown larger and was causing the girl more pain. Asumu and Kabuki told her to hang in there. Kabuki said he should call for Hibiki, but Asumu refused. Kabuki retorted that Hibiki might be able to do something as the sickness was from the Makamou's curse. Kabuki yelled that it was for her sake and Asumu reluctantly ran of. The Oni tended to her and told her it would be okay.

The Oni had gathered outside the village and Kirameki commented how stupid it was for them to fight amongst themselves. Touki agreed and said his training was clearly lacking. Asumu came running and begged Hibiki to come and help him with Hitoe.

Asumu and Hibiki came running in and saw Kabuki strangling Hitoe, but let her go when he realised they were there. The boy wondered what was going on. And Hitoe revealed that it was he who killed the villagers. Hibiki demanded to know what was going on, but Kabuki laughed. Kabuki revealed that he was trying to make the villagers hate the Oni even more so that the Oni would start fighting amongst themselves. If Hibiki had not arrived he would probably have accomplished that. Hibiki did not understand and asked what his objective was. Kabuki revealed that he was to kill all of the Oni in order to become a Makamou. Hibiki was confused, and Asumu reminded him of the time they first met and Kabuki was fighting a Makamou. Kabuki vaguely remembered it and he introduced them to her once more. Behind them appeared the Kaendaishou, and the Oni revealed it was all an act, as he had grown tired of the foolishness of adults. No matter how hard he had worked for them they always looked down on him and mocked him. To get revenge on those corrupted humans he would become a Makamou. Asumu was in disbelief and Kabuki told the Makamou to attack them. The Kaendaishou attacked and Hibiki started wrestling with it. Asumu grabbed Kabuki and demanded to know what he meant by attacking them. The Oni scoffed at him for thinking they were on the same side and pushed him against the wall. Hitoe tried to intervene but was pushed aside as the Oni said he hated humans. Hibiki threw Kabuki away but was knocked through a wall by the Kaendaishou. Habataki and Todoroki came running so Kabuki and the Makamou ran away. Hibiki made a concoction for Hitoe which cured her of her sickness, but the mark remained.

Asumu SP 15

Asumu and Hitoe were out walking when he remarked that he still could not believe that Kabuki had tried to attack him. He jokingly said an Oni was an Oni after all and not a human. Hitoe said that it was not so, as she was saved by Hibiki from the curse. Asumu was unsure as he thought it was Hibiki's fault for his brother's death. Hitoe then recalled a dream she had about Takeshi. In the dream he pointed her towards the cave by the sea. Asumu and Hitoe went there, and the boy revealed that it was his and his brother's secret hideout. They would hide their treasures there, he said as he went around while looking. They found a rolled up blade and brought it with them. When they came outside, some of the villagers came and dragged Hitoe away, accusing her of running away. Asumu tried to stop them but was pushed aside.

Asumu was convening with Tobee and was unsure of what they could do next to save Hitoe. Tobee said there was a gap between Oni and humans that could not be filled yet, and it was due to human foolishness. Tobee saw the dagger Asumu found who revealed that it was probably his brother's treasure. The village leader concluded that Takeshi must have made a katana for his teacher Hibiki. It was however unfinished so he had not been able to give it to Hibiki. The katana had Takeshi's soul and feelings for Hibiki imbued in it.

Asumu SP 16

Asumu decided to give the blade to Hibiki and headed of to his house. As he arrived he saw that Kabuki and the Kaendaishou was attacking Hibiki, but his arrival interrupted the battle. He pulled out the blade and walked towards Hibiki. Kabuki found it interesting that the boy would take his revenge for his brother. Asumu won over his anger however and gave the blade to Hibiki. Kabuki was surprised as Asumu told Hibiki to fight, as it was what his brother Takeshi would have wanted. Hibiki then noticed that his name was inscribed on the sword. Kabuki called it foolish and attacked them. Asumu told Hibiki to fight and he eventually had a change of heart and transformed. He started dueling with Kabuki and the Makamou. He eventually suceeded in disarming the Kaendaishou, but the Makamou took ahold of his arms and held them down with overpowering strength. The Makamou was about to bite him when Hibiki used his Kihōjutsu: Onibi which blew the head of the Kaendaishou. The Makamou crumbled to dust as Hibiki prepared himself for Kabuki who said he was not as weak as the Makamou.

Asumu watched as Kabuki sent out his Charcoal gray Crow Disc Animal, which turned giant and dragged Hibiki along the ground and of a cliff. The Oni used his own Rock crimson Lion Disc Animal which brought him safely down, which allowed him to send out a giant Madder Hawk which was able to defeat the crow. Kabuki grabbed a hold of Hibiki and pulled him of the lion. He was able to slash Hibiki with his Onsaken, and as Hibiki tried to retaliate, he blocked him with an umbrella, which allowed him to stab and slash Hibiki. The Echo Oni made some space between them as blood dripped from his wound. Kabuki charged at him to give the final blow, but while Kabuki repeated his block and thrust attack, Hibiki dodged it and hit Kabuki with several whacks of his Ongekibou. Kabuki untransformed as he fell to the ground, defeated. Hibki untransformed as well and ran to Asumu who was calling him and they both left to save Hitoe.

Asumu SP 17

Hitoe was praying to the gods as the Orochi descended upon her. The Makamou was suddenly knocked aside by a Kibōjutsu: Rekkadan fire blast from Hibiki who came galloping on his horse. Hitoe was happy to see Hibiki, but the Douji kept her in place. The Hime and Douji then summoned the Makamou Ninja Group around them. Hibiki transformed as he was riding and went to rampage among the Makamou. As the Oni fought, Asumu ran to Hitoe's side, but they were surrounded by the Makamou. Hibiki came to aid them and sent several fire blasts at Makamou. They tried to make a run for it but was stopped by the Douji and Hime. Hibiki did his best to fend of the Douji and Hime when suddenly Kirameki appeared. The Nagoyan threw his Ongekicymbal at the Makamou while saying he had had enough of running away. Habataki descended from the sky as well and said he had to fight, as otherwise he would not be able to face his wife. Nishiki and Touki came running as well, while the former said he would atleast dream of the treasure he had been promised, and the latter said he heard Buddha's voice saying it was time for battle. Todoroki and Ibuki then arrived and together they all joined in a circle around Asumu and Hitoe. Todoroki said he would have to fight for the humans after all, and Ibuki said it was something they had to do. The Makamou charged and a full out battle ensued. One after another they defeated the Ninja Makamou, as well as the Douji and Hime. Hibiki told Asumu and Hitoe to run away when he suddenly stood face to face with the young lady. Asumu watched as the lady turned into the Makamou, Hitotsumi and it engaged in battle with Hibiki. Hitotsumi suddenly disappeared but a giant version of his arm appeared and snatched Hibiki away. The six Oni went to help Hibiki and together they managed to defeat Hitotsumi. The Oni lined up on the beach as the Makamou was destroyed, when Orochi suddenly started shooting fireballs at them. Hibiki used his Snow white Ape Disc Animal which wrestled with the Makamou. As the Disc Animal grabbed a hold of the Orochi, Hibiki brandished Takeshi's blade and jumped at the Makamou. He was however knocked aside and the blade flew into the water. The other Oni came to his aide as the Orochi started shooting fireballs at them.

Asumu SP 18

It is unknown how the Oni defeated Orochi as the pages containing the story was missing. After Orochi's defeat, the Oni gathered at the village and smiled at the villagers as they said goodbye and left. All of the villagers bowed to them as thanks. Hitoe said that one day, humans and Oni would surely be able to understand eachother. Tobee proposed that they would create an organization that would help them, which the villagers agreed to. Asumu decided that the name of the organisation would be Takeshi, just like his brother.

Asumu and Hitoe would afterwards pray at Suzu's gravestone and hold hands as they ran on the beach.
