Lux Sano was never supposed to return. Separated from the Sano family as a child, Lux spent her early years in an orphanage alongside Izana Kurokawa and Kakucho — becoming the only person capable of calming Izana’s violent loneliness. But after suddenly being taken back into the Sano family, Lux is forced to leave behind the broken boy who saw her as his entire world. Years later, during the Tenjiku conflict, the past returns in the worst way possible. As Yokohama falls deeper into gang warfare, Lux becomes trapped between the people she once loved: Izana, who cannot let go of abandonment; Mikey, who fears losing another sibling to darkness; Chifuyu, who still believes she can be saved; and Sanzu, whose unsettling obsession with Lux threatens to destroy everything around them. In a world built on violence, grief, and loyalty twisted beyond repair, Lux must decide whether she truly belongs with the family she found… or the monsters who understand her best.
