>>281276957She went from a mischievous scheming ara ara maid with some playful genki tendencies as part of it to full LOLRANDUMB mode in Kagetsu Tohya and on, constantly switching between poor gimmicks like acting like a mad scientist/gamer/Chinese stereotype/witch cosplayer (inexplicably treated like a separate character) and just being overly excitable about everything instead of being the teasing mastermind she was in the original VN. At least the remake offloaded that shit onto Arach instead and stayed faithful to Kohaku's original personality, also giving her a new voice that's not ridiculously high-pitched like the one from Melty Blood was.
