Nightmare Hunter: My Cheat Is Another Me

In real life, he's a gamer personality: he sleeps through class and stays up all night playing games, a complete loser.

His other personalities are suppressed in his dreams, which is why his personality in real life is completely different from the one in his dreams.

By chance, the personality from his dreams and the one from real life switch places...

By day, he's the most dazzling top student in the school. By night, he's the maddest hunter in the dream world.

“Don't ask. If you do, the answer is that my cheat is another version of me.”
