Itsuka

Due to the kidnapping and murder of his classmates in his childhood, young Satoru blocked out his memories to survive the pain and survivor's guilt. Survivor's guilt is not rational; it is an emotional burden that torments those who are spared tragedy while others perish. In the adult Satoru, this guilt manifests itself at an extremely destructive subconscious level. At the beginning of the manga, Satoru sabotages himself. He doesn't allow himself to succeed as a manga artist, he doesn't deepen his relationships, and he lives precariously. Subconsciously, Satoru feels he has no right to enjoy a fulfilling life when the lives of Kayo, Hiromi, and Jun Shiratori were destroyed.

In Yashiro's psychology, the common barriers of morality, age, or gender do not exist; what attracts him is the purity of Satoru's soul and his ability to oppose him.
