Yatsuka Itsuki

Itsuki is the protagonist’s childhood friend and also a student council member. She appears to be a serious and dignified girl but she actually has a lot of daydreams and delusions about the protagonist, whom she cares about dearly. She also swaps between being tsuntsun and deredere. Her family lives in a dojo so she’s been trained in the martial arts ever since she was a little girl.
