[S.A= Seyri Ai] ➡Highest rank= #1 in assassinationclassroom (11/25/19) ➡A well trained assassin that's only in her teens, she's already established a name for herself, that being "Ghost". She moves so quite the target didn't know she was moving around them until she talked, but she'll make it so that she can hide and pop out again. After a recent kill she has been called to go to Kunugigaoka, to be a undercover student who will kill Koro-sensei. See how she'll go on about in her day to day lives making new friends, and possibly a romance blooming.
