As benkei's sister (you're just a year younger than him) you already know that he's in a gang, the first generation black dragons. But Benkei also hides you from the gang, of course he doesn't want you to be involved.

But one time, his friends who were also in the gang, Takeomi, Wakasa, and Shinichiro. You didn't expect them to be there but opened the door for them.

As you opened the door, they didn't expect a woman to open the door. "Oh, what a pretty lady Benkei got here." Wakasa said.
