Arimura is not only politically adept but also brilliant in both strategy and tactics, and as a result, has many enemies.

Because of this, there are rumours that she is, in some way, lacking as a person.

According to the protagonist: “In the presence of General Arimura, I feel a kind of tension I have rarely experienced.”
