Fukunaga Koharu

Bust like a cow, big ass.

A shy female student whose overly prominent breasts draw attention whether she wants it or not.
She's the only one at the academy who treats the protagonist kindly, often supporting him when Arisa isn't watching.
Though she has a complex about her overly large breasts, she's also notably sensitive in that area.
Her actions come from genuine goodwill, without deception or hidden motives.
However, this kindness is actually the result of Arisa's mind control.
She is being used as a tool to help control the protagonist, maintaining the dual role of being both his 'outlet and his persecutor'.

"…Um… I don’t… think you need to worry about it…"
