SC with Jay Onrait - S01

On her first day of junior high, Mato Kuroi crosses paths with Yomi Takanashi. Yomi is surprised by Mato's blunt personality at first, but the two quickly grow close, spending every day together. To mark their friendship, Mato gives Yomi a matching blue star phone charm-just like the one she carries. But when their second year begins, things shift. Assigned to separate classes, Mato starts hanging out more with Yuu Koutari, a girl from the basketball team. Before long, Mato and Yomi drift so far apart that Yomi seems to vanish entirely, leaving no trace. Meanwhile, in another world, Black Rock Shooter hunts down Dead Master. Though the two are enemies, their bond mirrors Mato and Yomi's. As their stories intertwine, the blue star charm-and the legendary gunslinger-might hold the key to Yomi's disappearance.
