A master of disguise, Saemon possesses the ability to transform into the likeness of others. Not only can he mimic the voice of his enemies, but he can also replicate their appearance with uncanny precision. This remarkable chameleon-like skill makes him a silent and deadly assassin.
However, there is another side to Saemon that few ever witness. As Okoi's eldest brother, he is undoubtedly a cheerful soul who loves his sister deeply. Their close bond seems almost telepathic, as Saemon always senses when she is in danger. When Okoi takes her final breaths, Saemon, disguised as Yasamaru, holds her hand. Driven by his love for his sister, he is determined to do whatever it takes to defeat the Iga and avenge her death.
