Shin Megami Tensei: Devil SummonerEdit
After the Protagonist is guided to his new "residence" by Charon, he must find his way out of the dungeon & get back to his own physical body. The dungeon consists of an entire warp maze, hence its name Infinite Hell. After the protagonist finds Charon again, declining the offer to get back to his physical body will cause him to reveal that Kyouji Kuzunoha was the one who asked to have your soul placed in his body. When the protagonist was about to be killed by Sid Davis, Charon quickly removed his soul & placed it on Kyouji's body so that he could act as his substitute and fulfill his duties. However, as a result from having his soul for being separated from his body too long, Kyouji has been dead ever since. Afterwards, he sends the protagonist's soul back to his body.
