‘It’s a warrior party in a fantasy novel, but it’s a role that has no presence than a villain, that’s who I am.’ After realizing his former life as a graduate s*ave, Cylon Hale, a wizard, tries to live an idle life, but he is reincarnated in a fantasy world where the demon king breathes, and mysteries run wild. As if on cue, he is chosen by the gods to be a companion to a warrior. If he doesn’t accept, he will become a traitor to his country. Cylon tries to resist his fate with his 21st-century democratic citizenship, which has infiltrated his mind with memories of his previous life. It’s, ‘become an extra colleague in a warrior party!’ I’m going to be a colleague who is not incompetent, not competent, and has no presence, and I’m going to sneak honey. The main character of the medieval fantasy is none other than the warrior, and since the warrior can’t be defeated by the demon king, he thinks he can only serve one person. Will Cylon be able to complete his adventure unnoticed?
