Asumu Adachi (安達 明日夢 Adachi Asumu) is the main character of Kamen Rider Hibiki. For a long time, he was called "boy" by Hibiki, as he was his apprentice. By the end of the season, Hibiki called him by his real name.

Character History


Asumu met Hibiki on the way to the memorial service at Yakushima Island before his high school entrance exam. Asumu met Hibiki on a cruise ship to Yakushima Island where he saved a young boy from falling off the ship. On the island, they meet once again before parting ways. Asumu later left his family and traveled by car into the mountains for sightseeing, only to be attacked by Tsuchigumo. Hibiki saves Asumu but afterwards, he saw Hibiki transform into an oni and he was interested in Hibiki ever since. But, after the incident, Asumu had little confidence in passing his exams to get into Jonan High and often seeked advice from Hibiki. After graduating from East Shibamata Junior High School, he enrolled in Jonan High School. He was placed in the same class as Hitomi Mochida and Akira Amami.

He would come to know the secret of the "Takeshi", because Hibiki said he is not willing to disciple, and did not have the feeling that he could after thinking he could do something else, "Tachibana" he only work part-time in the days with no activity.

He had begun training with the introduction of Kyousuke Kiriya, who also wanted to be an Oni. He finally succeeded in apprenticeship under Hibiki. Hibiki had them compete with each other to decide which of them Hibiki would take under his wing. Becoming an Oni can only be learned through training with Hibiki, defeating the Makamou.

Eventually, Asumu realized that being an Oni was not for him. He also quit his part-time job at Tachibana, aiming to be a doctor.

After that, he had communication with Takeshi, Only to reunite with two Oni (Kyousuke and Hibiki) a year later. He was training to be a doctor with knowledge of the courage and training obtained when he was an apprentice. He was able to reconcile with Kyousuke finally, a new teacher-student relationship in the rest of his life with Hibiki.

Kamen Rider Hibiki & The Seven Senki

He was saved by Hibiki when they faced a Makamou which causes Hibiki being injured. This leads Asumu in reading the book that contains the history of the said Makamou and entangled with the history of the Takeshi and the Oni. Learning that his meeting with the Oni is no mere coincidence.


to be added


In the Hyper Battle Video, Asumu was able to assume the form of Kamen Rider Hibiki with the help of the Disc Animals.

In this form, Hibiki is a purple demon. This is his basic form and the easiest form for him to reach. To become this form, Hibiki simply needs to tap his tuning fork against a solid surface, the vibrations from the fork causing his body to be engulfed in a fiery purple aura. Hibiki also gains a second "oni face" which is a crest that forms on his forehead. Unlike most Kamen Riders, Hibiki does not wear a suit, rather his demon form is his true form.

The third and final form Hibiki was able to reach is known as Hibiki Soukou or Armed Hibiki. Unlike Hibiki Kurenai that simply changes colors, the armor equipment effects here are much greater. To reach this form, Hibiki must use the Armed Saber, the Armed Saber also serves as a weapon in this form. When initiating the call Hibiki automatically assumes Hibiki Kurenai, he calls upon the power of the Disc Animals to fuse with him, each becoming armored for his form. Finally, his oni face is covered with a samurai like shield, his horns expand, and the little oni face on his forhead is covered with the character for Armed, 甲. Hibiki is able to destroy most lower level Makamou with little to no effort in this form.

Behind the Scenes



  • Initially, the idea was that the apprenticeship of Hibiki for five episodes. He was apprenticed at the discretion of the Takada Temple. The film also saw the completion of the pilot version of the first two episodes.
  • The words that make up Asumu's name (明日夢) can be read as "tomorrow" (明日 ashita) and "dream" ( yume).
  • A producer's blog posted around the conclusion of Hibiki stated that Asumu was originally supposed to become an Oni after all, but almost literal last-minute rewrites (which came in during the filming of the final battle) changed these plans. The producer claimed that there was a fully completed "Oni Asumu" costume, but it was scrapped in order to make Kyousuke Kiriya's Oni costume look better.
