Shuri Oumi

Oumi Shuri is a character introduced in Shinyaku Toaru Majutsu no Index as a competitor for the Natural Selector tournament. As a member of the Kouga School of ninjutsu, she is a queer-looking woman seeking interesting supernatural persons to help her school's prestige, she becomes an unwilling key character in the distortion in Baggage City as she tries to survive in the bloodbath and at the same time accomplish her goal.

Despite her being 30 years old, due to her disease, Shuri looks like a young girl barely out of elementary. The oldest of the three girls (Kumokawa Maria and Saflee Opendays), she is the most serious of all them. This maybe due to her advanced aged, and the unwavering dedication to her mission. When she was with the similarly strangely dressed Kumokawa Maria, she acted as the straight man to Maria's funny man, giving snarky comments regarding her quirky behavior, amongst other things. As a member of the Kouga School, she is works best with teamwork, as exemplified with her work with Maria, and later including Saflee Opendays.
