Yuuka Amato

Yuuka Amato (also spelled Yuka Amato in some translations) is a supporting character in the Maken-ki! anime. She's a third-year student at Tenbi Academy and serves as the treasurer/accountant of the Student Council's Security Division (Maken-ki).

In the anime, Yuuka is portrayed as generally carefree and laid-back with a bright, cheerful demeanor, but she's also quite cunning and clever. She often comes up with schemes or activities—frequently with a playful or mischievous twist—that help generate funds or get tasks done, like organizing unusual "matches" or events that double as work. She's especially known for teasing her close friend Furan Takaki (the Security Division president), often in cheeky ways like flashing or messing with her.

She's revealed to be a skilled ninja (from a family lineage serving as oniwaban/guards), which ties into her resourceful and tactical side. Additionally, she's the younger sister of Tomiko Amado, Takeru Ooyama's homeroom teacher, and the two share a similarly warm and friendly personality.

Overall, she brings a relaxed, optimistic, and slyly manipulative energy to the group while supporting the main cast in her role.
