On the first day of school, the state distributes spirit beasts according to grades. The squad leader with the best grades chose the SSS-level nine-tailed silver fox without hesitation, while I, who was ranked last, was only assigned an F-level brown bear. But not long after, the extremely cold apocalypse came. I signed a contract with a brown bear and gained his cold-resistant talent. However, the nine-tailed fox chosen by the monitor froze to death on the first day of the apocalypse before he could grow up. He went crazy with jealousy, led other classmates to sneak attack on my brown bear, and cooked bear meat hot pot in front of me to feast on. I was filled with grief and anger and vomited blood and died on the spot. When I woke up again, I found myself back on the day when the spirit beasts were assigned.
