幸坂 小鳥

'Little sister who wants to be treated like an adult' Shuuji's kid sister, she's gotten to the age where she tries to act mature and speak like an adult. Around the same mental age as Iroha, she quickly befriends her and tries to show her the ropes. Though she can sometimes be selfish, Kotori is a kind girl who is considerate of others' feelings. "Well, duh! I am a lady, after all!" [From Denpasoft's Website]
