Kotoha is an exceptional member of the Covert Squad who excels at using shurikens as her weapon. She initially views Kuon with suspicion and sees her as a threat when her true identity is exposed, but later comes to accept her leadership once more. Despite not smiling often, Kotoha did so towards Kuon at the end of episode 16. Additionally, she has mastered unarmed combat and disguise, successfully posing as the caretaker of Gokujou-ryou during a soccer match between the Gokujou Seitokai and another school's student council in episode 11. Despite being behind by a significant margin early on, Kotoha single-handedly won the game for her team.
