(Fake), Ryuubi

劉備

Anime version
A charismatic young commander. He should not be confused with Ryūbi from Shin Koihime Musō, as that character is female and lacks a real name. He first appears in episode 11, leading the Touka Village militia against bandits, where Aisha and Rinrin help them defeat the attackers. Gentoku claims to be a descendant of Ryuushou and secured an army from the Feudal Lord of Touka because he and his followers were on a quest to defeat the bandits. However, his army was defeated seven times, leading to his reputation as a commander who loses every battle; at one point, the lord considered dismissing him if he lost again. Thanks to the help of Aisha and Rinrin, along with Shuri's strategies, Gentoku and his men were able to defeat the bandits one by one. He is also skilled with women, being the first person to recognize Aisha as the famous Beautiful Black Hair Bandit Fighter without the usual skepticism regarding her beauty, and he even charmed General Kashin herself, earning her trust.
As his reputation grows, along with his alleged relationship with Aisha (since he resembles her late older brother), Rinrin begins to distrust him, suspecting something suspicious about him. These suspicions are confirmed when Gentoku and his men attend an imperial war meeting held by General Kashin. While Touka is attacked by a large army of bandits, he refuses to go and help the village, focusing instead on his mission to defeat rebels, which was given to him by Kashin. Aisha tries to make him reconsider, but he attempts to seduce Aisha into joining his mission instead and forgetting the village. Realizing that Gentoku never cared about saving people and was only interested in fame, glory, and his twisted view of justice, Aisha slaps him and leaves him, along with Bachō, to save their friends. Without those two, Gentoku's army is defeated in battle, and he receives a severe scolding from General Kashin. He tries to save face by returning to Touka, only to meet two unexpected guests, Kōchū and Riri, who immediately recognize him as the man who kidnapped Riri and threatened Kōchū to commit an assassination. With his identity exposed, he runs away, and Kōchū concludes he was nothing more than a no-good impostor who lied about his ancestry and identity to gain fame.
In Shin Koihime Musō, it is revealed that he stole the name Ryūbi Gentoku from a girl (the real Ryūbi Gentoku) along with her sword prior to his appearance in the first series. He then became the target of said girl, who intended to retrieve her sword and clear her name. He is later found to have lost the sword due to raids on bandit hideouts, and his current whereabouts are unknown.
