The monitor and I were arranged by the school to select spiritual beasts at the same time. She, who was number one in the class, chose the nine-tailed silver fox with the purest blood, and as the last one, I could only be assigned a brown bear with the most mixed blood. Unexpectedly, the extreme cold apocalypse came soon, and I made a contract with the brown bear to share the brown bear's cold-resistant talent. However, the monitor's nine-tailed fox had no time to grow and develop, and was frozen to death on the first day of the apocalypse. Out of jealousy, the monitor threatened that he could gain the ability to withstand the cold by eating brown bear meat.
