This forum needs a favorite character thread; you can list as many as you want. For me:
Sanya V. Litvyak: I just really adore her, she's just the type you want to look out for. She plays the piano too, and I'm really appealed to that.
Mio Sakamoto: I love her warrior mentality. But while she's strict and disciplinary, she always shows it with love. She also has the best laugh ever!
Gertrud Barkhorn: Gotta love Trude! I'm just appealed to tsunderes, and she's about as tsundere as it gets in this show. On a side note, she and Erica are also hilarious together
