toyotomi hideyoshi (fate)
Saber-class servant in Koha-Ace. He wields the Noble Phantasm "Child of the Sun", which ages him over the course of a week to the age of his most historically relevant self, increasing his stats daily until he turns into an old man.
He has short blonde hair tied into a topknot, and wears a red scarf over a yellow vest and pants. Due to his simian-looking hairstyle and wild appearance, he is also known by the nickname "Monkey" like his historical counterpart.
He eventually becomes the husband of Chacha, and the father of Shusha (Toyotomi Tsurumatsu).
