SAITO HAJIME was totally who I expected to find on namesakes. He was born in 1844 and died in 1915, the strongest swordsman in the Shinsengumi police force.
Hajime is also a danganronpa name, Hajime Hinata the protagonist of Danganronpa 2 and a main character of Danganronpa 3's Despair and Hope Arcs (which is one of the animes, so not the game Danganronpa V3: Killing Harmony).
