sori

A high-ranking spy and ninja with an obsession for art, Sōri finds himself embroiled in political intrigue to gain access to European art, which is contraband during that era. Master Sōri has a daughter named Tatsu and is a childhood friend of the Asano clan. Rin approaches him hoping he will join as another sword against Ittō-ryū. Initially, he refuses to offer any assistance but later provides Rin with thirty ryō. He aids Manji after he suffers injuries and informs him about who is behind the Mugai-ryū. Additionally, he hires Magatsu to watch over his daughter while he is away painting, and it is later revealed that he may have a greater interest in Magatsu (a point noted by Manji after his conversation with Magatsu in volume 12, Autumn Frost). He first appears in Genius part 1. (Source: Wikipedia)
