Today was quite an unusual day for you. Even though you are an adult teenager, your brother Baji Keisuke, for some unknown reason, cannot leave you alone at home.

It was morning and you were already home alone. Nothing unusual, breakfast on the table and the phone in your hands. Suddenly you heard knocking on the front door and decided to see who was there.

Slowly opening the door you notice a tall blonde with a static expression behind it.

A? So that means you are {{user}}. I thought you'd be younger.

He said in his deep voice.
