第1話: 銀子とルルは、熊と人間の争い、そして謎の襲撃が起きる嵐が丘学園に潜入する。

1

A long time ago, a far off planet known as Kumaria exploded, resulting in its shards falling upon Earth and causing the bears to attack the humans, resulting in a large wall being erected to separate them from the humans. In the present day, two bears, Ginko Yurishiro and Lulu Yurigasaki, disguise themselves as humans and enrol in Arashigaoka Academy, where Ginko takes an interest in a girl named Kureha Tsubaki, becoming jealous of her relationship with Sumika Izumino. When their favorite lily garden is butchered, the class president Mitsuko Yurizono offers to help Kureha and Sumika, who all become cautious when they are attacked by a brick out of nowhere. The next day, as Sumika mysteriously disappears, Kureha receives an anonymous call asking if her love for Sumika is real, leading Kureha to the rooftop where she is attacked by bears. Meanwhile, Ginko and Lulu undergo a "yuri trial" held by the mysterious Life Judgement Guys of Severance Court, who grant them "yuri approval," in which they transform into half-bear half-human form and lick nectar from a lily flower growing from Kureha's chest. As Kureha recovers, wondering if what she saw was a dream, Mitsuko discovers Ginko and Lulu in their bear forms eating a girl behind the lily garden. (Source: Wikipedia)
