It tells the story of a squirrel facing a group of powerful and perverted non-human attacks.
Shou is not considered a weak person, but he encounters people who are stronger than him. Strength is respected, and he will grow from a strong person to a stronger person.
(The main attackers in this article are sadistic, possessive, and angry with both humans and gods. There are also two or three inefficient bastard attacks, so don't enter with caution.)
