Become an Old One

It's just a third-rate detective's consultant. Because he hasn't received any commissions for a long time, he is forced to face the risk of bankruptcy. But suddenly one day, he received a strange disappearance investigation commission. A strange necklace and an extremely bizarre disappearance revealed another side of the world that ordinary people don't know about before his eyes. From then on, his life became turbulent and strange. The clown hiding in the light in the dark night. . . . . . The deceased who has died long ago but has integrated into normal life. . . . . . The non-existent demon twins. . . . . . Is everything the power of the gods, or is it the secret work of people with ulterior motives?
