A mysterious ninja girl who often appears unexpectedly. Agiri is a calm, friendly, and laid back individual. She is from the same organization as Sonya, and transferred to her school for some assignments. She stays at a former ninja club room without the school's permission. Agiri often perplexes Sonya and Yasuna with her dubious "ninjutsu," often calling the common way of dealing things as her "special ninja techniques." She is able to perform those tricks without ever letting Yasuna or even Sonya know how she did it and how to do it. Though Yasuna is often fooled by Agiri's dumb logic, Sonya considers her untrustworthy. Her parents are farmers, while some of her other relatives own a theme park of their own. She seems to come from a lineage of ninjas, considering the sheer amount of ninja-themed object and 'ninjutsu' she has. she often sells items to yasuna advertising them as ninja techniques, only for them to be a scam, she often has her eyes closed yet can still see perfectly.
