A manga written and drawn by Shiori Teshirogi. The Justice League discovers Lex Luthor and the Joker trying to remake the universe by harnessing the energy of Earth's "ley lines." At the same time, teenager Rui Aramiya is searching for his missing parents, who are somehow connected to the current crisis. Originally published on November 3 2017, an English version was released on October 17 2018.
- Martial Pacifist: Rui was trained in the ninja arts by his father. However, Rui hates violence, so he never fights unless he's forced to defend himself and even then only uses the bare minimum force required, which has almost gotten him killed at least once.
- The Aloner: Batman initially refuses the League's assistance due to the grief of Jason Todd's death clouding his judgment.
