Also known as: Tchaiko
A character reimagining of the historical composer Tchaikovsky, except she's been transformed into a beautiful girl who speaks in a thick Tohoku dialect—a pretty wild departure from the original. She's part of the idol unit CLASKEY:KLASKY (usually shortened to CLA:KLA), alongside Bądarzewska.
What makes her stand out is her rare ability to actually understand what Bach meant by his musical terminology, something fans often note sets her apart even among the classically-minded cast. It's one of those oddly specific talents that works surprisingly well for her character.
