Synopsis

Ruka and Rumi Kobayakawa are twin sisters who both have feelings for Katsuyuki Touma, an athletic upperclassman. Rumi initially seems cool with Ruka pursuing him—until the two girls get infected by some kind of strange bacterium. The infection warps Rumi's personality and unlocks psychic powers in both of them. Now Rumi becomes obsessed with Katsuyuki and will do whatever it takes to have him, even if it means going after her own twin sister.
