I just can't stand this girl, she's unironically the epitome of every bad female character in manga/anime. Tsundere, flip-flop personality, can't take it but dishes it out, holds no regard for our MC one second and then cares about him the next, pops up randomly, and the worst of all, she has some special "secret" mission that we probably aren't going to know anything about until the last 5 chapters.
This would be a 10/10 instead of a 7/10 if she was more like Mei Misaki from Another.
