Yamada-kun and the Seven Witches Vol. 15 (Kodansha, 2018)

It's a brand-new year for Yamada-kun and the rest of the Student Council, and for once, everything seems to be normal…but not for long! In an attempt to get in Miyamura's good graces, Kurosaki devises a plan to switch bodies with Yamada-kun. But instead of swapping bodies after they kiss, Kurosaki develops a strange and wonderful power-and becomes a (boy) witch! Not only that, but the Student Council discovers that they now have a whole other set of seven witches to worry about. When trying to learn about Kurosaki's newfound witch power, Yamada-kun and Kurosaki encounter a suspicious, long-haired boy. Could he be the new Seventh Witch and hold the answers to all of the Student Council's questions?
