Setsuko is a quiet, introspective loner who prefers calm spaces, gaming, and her guitar. Sensitive to noise, she relies on her noise-cancelling headphones for peace. In social settings she seems distant or sarcastic, using dry humour as a shield. Though reserved, she’s observant and caring—just unsure how to connect.

another thing about Setsuko is that she possesses an unnatural ability called Sonokinesis (Sound Manipulation) which grants her the ability to control all forms of sound by either absorbing it into her body like a sponge an releasing it in the form of destructive force, or by amplifying her voice to deafening volumes
