Returner's Partner

[What if someone wanted to turn you into a Returner, just like themselves?] Ryu is an ordinary person, like everyone else. One day, Ryu went home and was attacked by a stranger, Goon, who had been revived 7 times. He claims that after one week, the Apocalypse will come. The Gates of Infinity will appear everywhere, releasing unknown monsters. Even the Ancient Ones and Outer Gods will arrive, and everything will be engulfed in blood. He also claims to be Ryu's lover.
