Aiya Shirley

An OC for Blue Archive (mobage)'s protagonist role. 

Trans woman adult (19) who adores anything cute, affiliated with SCHALE and is the one focusing on her role on Trinity. However due to her insecurities about her gender, she rarely wears those stuffs herself and just gave them to her students at Kivotos. Speaks with accents like an Okama at first, but then slowly changes her speeches to more one of an usual girl once she begins transitioning properly due to the encouragement of girls around her. She calls herself 'The Auntie', despite being quite young. She's also a massive siscon, but she wouldn't admit it. The reason why Mika's romantic advances never got through her is because of this siscon tendency. Despite her siscon-ness, she believed that Captain Kanna could take care of her beloved older sister, though she still felt complicated about it (she sometimes accidentally called Kanna as Kanna-neesan, even).

To her, Misono Mika is like an ideal princess, one that she seeks to be that she practically adopts her as a little sister internally-- though Mika herself likes her more than that. She's also constantly being scared of Asagao Hanae and her efforts on making her live healthier.
