A meteor shower turns all bears violent, a wall separates two species, and somehow this becomes a love story that breaks you. The romance between Kureha and Sumika is not a subplot, it is the reason the entire symbolic machinery exists. What starts as absurdist genre setup becomes a genuine cry about loving someone across an impossible divide, and by the end you understand why Ikuhara needed meteors and bears and magical girls to say what he actually meant.

After a small planet explodes and its fragments fall to Earth as a meteor shower, every bear in the world turns violent and starts attacking humans. To end the bloodshed, a great Wall of Severance is raised between the two sides. Kureha Tsubaki and Sumika Izumino are two girls in love at Arashigaoka Academy. One morning, as they watch lilies bloom, a Bear Alarm rings out. Two bears, Ginko Yurishiro and Lulu Yurigasaki, have slipped past the wall and entered the school, and they seem to see the bear-hating Kureha as more than a meal. Their closeness to her starts to expose hidden secrets, and when these relationships draw the attention of the Invisible Storm, a group that enforces order at the academy, the girls must defend their love on the way to a promised kiss. The series blends fantasy, magical girl elements, psychological drama and romance.
