Morishige likes to leave a good impression on other people while hiding his inner personality. He acts stoic and collected, taking situations like his best friend's transfer and being encased in Heavenly Host Elementary School in his stride. Sakutaro takes great pride in his family heritage and reacts violently when other people make fun of his name. Unlike the rest of the characters, he is neither disgusted nor horrified by the excessive gore and decaying corpses he finds them comforting.
