Yoko Minato

"I've finally found the qualified one who can guide us to the future."

- Minato's opinion on Kaito's leadership during an-all assault over the armies of Inves

Yoko Minato (湊 耀子) was one of Ryoma Sengoku's subordinates who would later become one of Kaito Kumon's faithful followers after noticing his leadership during the Helheim Invasion. As a member of Yggdrasill Corporation, she uses a Genesis Driver and the Peach Energy Lockseed to transform into Kamen Rider Marika (仮面ライダーマリカ).

Personality
Yoko was a quiet soul, but she had a tendency to use excessive force, as seen by beating Kaito down when he loudly got up in a rage during his talk with Ryoma Sengoku, with Kouta soon joining him.

She seemed to be loyal to Ryoma Sengoku, though this was implied to be a facade. She had some kind of personal interest in Kaito, which Ryoma notes as strange, as she usually didn't involve herself with others. After Ryoma abandons her, she revealed that her loyalty to him was surface-level and that she sees more potential in Kaito.

She had no personal interest in obtaining the Forbidden Fruit, preferring to see ambitious people like Kaito reach for its power.

Past
Prior the event where Yoko was recruited into Yggdrasill, she was a former spy working for a certain organization. She infiltrated Yggdrasill, getting the files from a lab computer, until she was caught by Ryoma Sengoku. Instead of Yoko trying to fight him, Ryoma gives her an offer, to work with him in Yggdrasill as his assistant and bodyguard in which she eventually accepted.

During the testing period to realize a functional Sengoku Driver, she thought highly of Takatora Kureshima and Ryoma Sengoku. However, to her confusion, Ryoma tells her to not forward the images of an higher-intellect Inves to Takatora, but to him directly, instead.

Yggdrasill Saga
When Gaim attempts to stop Ryoji after his descent to an Inves, she along with the other Yggdrasill members transform. She spectates Sigurd as he kills Ryoji. Serving as a bodyguard for Ryoma Sengoku, she easily defeats Kouta and Kaito, both trying to escape and also take back their Drivers without Ryoma realizing. During Gaim and Baron's escape from Headquarters, under the guise of Marika, she stops Sigurd's fatal shot towards the two Armored Riders. After Mitsuzane Kureshima became the company's newest member before his first task, Minato and Ryoma were told by Sid about Mitsuzane's inner darkness, and thus reveals to be true as Sid suspected. Yoko assists Mitsuzane, with the help of the Charmant owner, Oren and the former Beat Rider Jonouchi to retrieve the Sengoku Driver from Kouta by kidnapping his sister, Akira Kazuraba. The plan fails when Oren reveals he'd rather use a clean way of kidnapping Akira, which also sabotages Hideyasu on switching his Donguri Lockseed with a fake one when he's about to transform and torture Akira while posing as his patissier assistant. After Bravo is beaten by Gaim in Jimber Lemon Arms, she appears to fight him. As she manages to evenly match Gaim, Mitsuzane, who transformed into Ryugen shoots Marika and telling her that he will protect Kouta.

Helheim Saga & Over Lord Saga
After hearing an opinion of Kaito's new decision to fill an absolute power like the Helheim's power merging with the Earth, on the next day, Yoko informed Takatora that Sid was attacked and almost killed the day before by the same unknown assailant who somehow produced Helheim power and identity unknown, and attacked/killed most of the Kurokage Troopers if they found every single Helheim plants surround them all the sudden. In the second day of the morning, Yoko found a Helheim plant trail that ended in the dark power engineering room, where she soon learned it might be a trapped by the assailant. As she sensed the assailant is nearby, she dodge the assailant's attack, who later revealed the identity as an Armored Rider who can produce Helheim's power. Surviving the attack as Marika, she was able to fight back until the Helheim powered Armored Rider escaped, she is able to confirm both Ryoma and Takatora, the assailant's identity as an Armored Rider who can produce Helheim's power.

Yoko, along with numerous Kurokage Troopers defended a Crack from Rampant Inves. However, when Gaim also joins the fight to protect Zawame City from burning to ashes, he takes the opportunity to steal Yoko's Lockseed. Yoko, powerless, watches Kouta run off to Headquarters as he is determined to stop Yggdrasill.

As Ryoma decides to kick Kaito off their team after analyzing the Over Lords' data, Yoko asked him to give Kaito one more chance. Surprised at her request, Ryoma decides to give him one more chance as he gives Yoko a Genesis Driver and the Lemon Energy Lockseed. Mitsuzane enters Ryoma's office as he hasn't told Takatora about the Over Lords yet. He also told them that they could find the Over Lords easily if they follow his plan.

Later, Yoko delivers the Genesis Driver to Kaito before she leaves. In the Helheim forest, Yoko gave the location of the Over Lords to Kaito and later as Marika, she attacks Gaim, but Ryugen blocks it as she continues fighting Gaim, following Mitsuzane's plan. Overpowered by Gaim, the Armored Rider leaves as Mitsuzane was surprised that Yoko was easily defeated.

Later, an alarm is triggered, Yoko, along with Sid enters Ryoma's office as they suspect that the Over Lords made their move.

However, Sid back-stabs Ryoma and Yoko as he destroys the equipment that keeps the Crack open and leaves as it starts to close. As the Over Lord, Demushu enters Zawame, Ryoma ordered Yoko to capture the Over Lord. However knowing the Kouta was there, he then ordered her and the Kurokage Troopers to eliminate him. Marika arrives just in time to stop Gaim from finishing off the Over Lord as the monster mercilessly attacks them, resulting in rendering Kouta unconscious. Before she could eliminate Kouta, Baron stops her and retreats as he told her that Kouta could help them. As the Kurokage Troopers were badly beaten by Demushu, Marika called Ryoma that they should retreat, however he still wants to capture the Over Lord for the Forbidden Fruit.

Seeing that Ryoma has become obsessed about the Forbidden Fruit, Zack and Kaito appears to aid them. Seeing the two Riders over powering the Over Lord, Yoko and the Kurokage Troopers were ordered by Ryoma to interfere and let Demushu escape. Later, she was abandoned by Ryoma when the Inves started to invade Zawame as they appeared from the tower. She receives assistance from Kaito, Zack, Oren, and Jonouchi to battle the Inves as she was amazed by Kaito's leadership.

However Demushu overpowered them all with his evolved form until they were saved when Kouta uses his new Kiwami Arms to defeat the Demushu. Yoko then cooperates with the Beat Riders as they would defend Zawame from Inves without any help from the government outside of Zawame.

When searching for the Over Lord, Yoko tells Kouta that there should only be one that obtains the Forbidden Fruit and that he cannot beat Kaito. Before they can finish their conversation, Dyudyuonshu interferes, leaving Kouta to chase after the Over Lord.

After Kouta now realized the Zangetsu Shin he saw recently is not Takatora and siding with the Over Lord, thanks to Oren's sense on the impostor's fighting ability, Yoko soon realized from the beginning after her betrayal of Takatora that Mitsuzane took his older brother's Genesis Driver, helped Sid after he betrayed Ryoma and Minato are related to Over Lord's invasion when Ryoma recently escaped. With Mitsuzane returns to Team Gaim's garage, Yoko is about to go to Mitsuzane until he is stopped by Kaito, who noticed what Yoko realized to threaten Mitsuzane to talk to her outside in private.

Later, Kouta decides to plan on attacking the Inves in the Tower, which Yoko agrees as they also plan to is save to kidnapped civilians from the Inves. Once arriving to one of the entrance on the tower, the entrance was guarded by Inves as Kouta thinks that Mitsuzane would be needed. However Kaito and Yoko tell Kouta that he was completely manipulated by him, but he refuses to believe them until they got their cover blown by an Inves.

When Takatora survived and made it return to an infested Zawame, Yoko told him what happened when Takatora was gone and staying in Helheim for a bit, thus being forgiven by him because she was only follow orders. When Ryoma is suddenly return after Takatora disappeared again, only left is his Sengoku Driver and Melon Lockseed, most of the resistance needs to think back about Ryoma as Yoko had a feeling and tells the resistances to stay sharp that Ryoma may soon betrayed the resistance, once he got the Forbidden Fruit like how he did to Takatora.

As Ryoma returns to Zawame, he inform to the group that they can enter the tower by a secret pathway that the scientist used before, however Yoko started to sense that he might be lying. Yoko would follow the Armored Riders to the secret pathway to reach Yggdrasill tower. However, once they reach to the pathway, Ryoma forgot to turn off the security system as she, along with Kaito and Zack hold off the Suika Arms Armors and the Tulip Hoppers.

In the aftermath of the Over Lords' extinction, Yoko stays alongside Kaito, who discovers during an encounter against Inves that Kaito is dying from the wound infection caused by Redyue. She stands besides Kaito, still wanting to be by his side until the end. Her Genesis Driver is later destroyed by Ryoma when she and Kaito intend on killing Ryoma for murdering Mai.
