Yagen Toushirou is one of many Awataguchi siblings in Touken Ranbu: Hanamaru.


In Touken Ranbu, Yagen has an aloof personality. He is also described as confident and brave most likely due to the influence of Oda Nobunaga


In the 15th century, his owner Hatakeyama Masanaga attempted to commit ritual suicide using him, but the wound wasn't severe enough to end his life. Frustrated, Masanaga threw the sword and it pierced straight into a medicinal stone mill -- a yagen.

Being strong enough to pierce stone but not enough to kill Masanaga led him to believe that the sword would never injure its master. From there on, Yagen gained the name of this object, and the legend that came with it.
