Ruru: Roar roar! Once upon a time, the asteroid belt Kumaria exploded. Kumaria, which had turned into bits, became a meteor shower, and showered onto Earth, but... Then bears became violent and began attacking people! I know, it's such a shocker! The humans made a wall to separate themselves, and tried to scare us bears away, but human rules mean nothing to us!
Ginko: Is your "love" real? We hated you all from the beginning, and loved you all from the beginning. That's why we wanted to become your true friends and cross that wall.
Ruru: Kureha Tsubaki... Kure-chin, huh? I wonder why kind of a girl she is... I'll bet she's a super delicious girl! Roar! Roar! I transformed into a human and transferred into Arashigaoka Academy. Teeheehee! It looks like no one has noticed that we're bears! That girl, and that girl, lots of them! Wow! They all smell so delicious! Roar! I'm going to do my best and eat a yummy-looking girl!
Ginko: This is a challenge from the wall of separation.
Text: A modern myth revolving lovers who have been separated.
Ginko: If your love is real, a bear will be waiting for you. If you give yourself up to the bear, your love will be recognized.
Text: Yuri, recognized
Ginko: I won't give up on love. I'm going to eat that girl. Yuri Kuma Arashi. Without being taken away by that transparent storm, I'm going to find it.
И текст с сайта (тоже не поможет):
Some time ago, the asteroid Kumaria exploded in the depths of space.
The resulting fragments became a meteor shower that rained down on Earth, and for some reason, bears all over the world rose up and attacked humanity! In "Man vs. Bear," the bears ate the humans and the humans shot the bears, resulting in a seemingly unending battle and a cycle of hatred. In the end, a giant "Wall of Extinction" was erected between the humans and bears and a state of mutual nonaggression came to pass….
The human world.
One morning, Arashigaoka Academy students Kureha Tsubaki and Sumika Izumino were by themselves and saw the "Yuri Flower" that bloomed in a flower bed. The two are friends as well as lovers. The flower bed is an important place to the two. At that moment, the Bear Alarms ring out! The bears are invading the human world, and humans are being attacked! Are they really those bears? One mystery invokes yet another mystery, one after another. The curtain rises magnificently on Yuri Kuma Arashi!
