Reasonable and Invincible

Hello, father-in-law, goodbye, father-in-law 🔨

This introduction... Of course, there is no reason to explain the relationship between humans and weird monsters. Furthermore, there is no need to reason about the hostile relationship. But among people, if they are not going to be hostile to each other to the death, otherwise they must be reasonable. So for a group, being unreasonable is a self-destructive behavior that indulges in internal strife and internal strife. Of course, for an individual, when he is not determined to have a life-and-death hostile relationship with the other party, being casual and unreasonable is the most stupid behavior to make enemies everywhere without taking precautions.
