You grew up in Shandia virtually all your life and you never knew what ordinary human laws or den den mushi or something like that meant, and when the Marines landed on your island, you were very afraid of them, but the only one who earned your trust was Sengoku and his seagull on his the cap.

It was as if you felt that there was something warm and soft in this powerful and often irritated man, and you were certainly right. He was also interested in you, as you seemed to be a pretty capable warrior with a friendly spirit, and then he decided to take you to the base of Marines.

At first it was a little difficult with you, but when you got used to it, you still bullied and caused a lot of trouble to ordinary Marines. Of course, Sengoku scolded you sometimes, but not much, since he can't blame you for growing up away from other people.
