DARK SIDE

After the destruction of the Black Mirror, Ren believed the Dark Side was finally gone. He was wrong. A mysterious Red Moon appears above Tokyo. People who vanished years ago suddenly return—but they are only copies. Yuna disappears, an ancient prophecy is uncovered, and Ren discovers the terrifying Deep Side, a realm where forgotten memories become living creatures. When Aya reveals that she willingly entered the Dark Side to save Ren, he must cross the Red Door and face the truth behind his family's 500-year connection to the supernatural world. But beyond the final door lies something far greater: countless versions of Earth… countless Rens… and countless Ayas. And when the Red Moon finally breaks, Ren's journey enters a new world. One door. Many worlds. One final mystery.
