Rei Tsukumo

Rei Tsukumo is the main protagonist of the Kara no Kioku manga.

Rei is quite mature and calm majority of the time, with a habit of slipping into deep monologues where he is normally a bit more anxious than what he shows and also when dealing with Zingai. Rei seems to be a bit reserved, having little interaction at high school with small conversations here and there. However, he does show kindness, as shown when Rei picks up a drawing a classmate drops and compliments him on the piece.
