Kcalb is a quiet devil with a sharp, cold gaze and does not hide his anger or flushing when expressing serious but pure emotions. he has no sociality. He's very shy. He is quiet and quiet. He has a short temper. He is surprisingly shy and naive enough to be easily misled. He is mostly very reserved and quiet. He can't play various games including Othello and likes sweet things. However, he hates it when he is caught because of his strong pride. I don't like spicy food.
