Souichi Gotou
About
Then he came back to life. Souichi was actually being kept alive by the negative energy of demonic spirits. He stood a strong chance of becoming purely an evil spirit unless Tamaki, and a medium in training, could perform an exorcism; however, this would kill Souichi. Tamaki even contemplated exorcising Souichi without him knowing it, but dismissed that idea as showing Souichi no respect at all. Meanwhile, Souichi's mother comes on her own to Tamaki's temple and, fearful of her son's demonic power, begs for her son to be exorcised.
In the end, with his parents still unable to forgive Souichi for not being the son they wanted, unwilling to love him the way the butterflies did, Souichi confronts Tamaki, who has to exorcise his demons even if it means that Souichi dies again. Tamaki almost died himself, except that his girlfriend Asahi brought him the rosary that he had forgotten; Tamaki needed the rosary to protect himself during the exorcism. As Asahi put it, "I chose your life over Souichi's, so we'll just have to be unforgivable together."
