The protagonist got acquainted with a ghost who called himself "Sharon, the Summoner of the Undead" in an unexpected situation. He came to the Bump Competition with a very mission-oriented mission, but was attacked and died by a contestant in the elimination round, and ended up ranked 205th.
However, due to the special limitations of his own power, he did not die. Instead, he lodged his soul in the brain of the heroine at the cost of losing part of his memory, talked to her with his own consciousness, and took her from the ordinary world to participate in the Bump Competition, inheriting the name and identity of "Summoner Sharon", as well as his abilities.
205'S ability also affects the protagonist and forgets what happened before the time travel and causes memory confusion with Sharon himself. However, they must rely on the only remaining means to win the competition and find out the real culprit who attacked 205 and his purpose in participating in the competition.
