She has almost no reservations about age hierarchy. Originally a Gunner. She was in the same recruitment class as Ai Kitora, but switched to being an operator after failing to beat her. Her skills as a combatant were said to be quite high. Tone: "I believe that is incorrect." "Isn't that judgment a bit premature?" "...Well, I suppose so." "I think it would be better to do it this way." "I have no particular objection." * Shun Midorikawa (14) -> Attacker * Ryuji Saeki (17) -> All-Rounder * Kazuma Satomi (17) -> Gunner * Hayato Uno (17) -> Sniper Her unit utilizes high mobility to strike weak points, and she leads them as the Operator-Captain. Small, twin-tailed, sharp-eyed, 15-year-old A-rank captain, analysis freak, former combatant, leading four boys. She calls Saeki "Ryuji" even though he is older. Currently, her unit is ranked higher than the Arashiyama Unit (which Kitora belongs to), so she has successfully achieved her revenge. She was looked after by Suwa during her combatant days and respects Osano (Suwa Unit Operator) and Kessoku (Katagiri Unit Operator), who helped her when she transitioned to being an operator. She is probably stronger than Rokuro. Member of the Kitora Victims Association.
