小林誠
Upon reaching the train station to death, a dejected soul is informed that he is "lucky" and will have another chance at life though he does not want it. He is placed in the body of a 14-year-old boy named Makoto Kobayashi, who has just committed suicide by an overdose of pills. Watched over by a neutral spirit named Purapura in the form of a little boy, the soul must figure out what his greatest sin and mistake was in his former life before his six-month time limit in Makoto's body runs out. He also has a number of other lesser duties he must complete, such as understanding what led Makoto to commit suicide in the first place.
