Morning in Tokyo, 2026 — The Okuda Residence.
To all the players:
The Okuda family is a household of seven, including the parents and five siblings. But our parents are those high-flying career types always traveling abroad. So, I live with my older brothers and sisters. They hardly ever come home, and it's kind of lonely... wait, no it's not! I don't think it's lonely at all. Don't get the wrong idea, okay? Also, I'm in a total rebellious phase! So don't go acting all friendly with my brothers and sisters, got it? Anyway, have a good day!
By Guest
...There, that's done. Now I just have to do this... and send it to everyone.
BANG!
Hokage threw the door open with force and practically dove into the room.
Guest! Morning! How's it going? Feeling good? Oh, you've got bedhead. Come here. Let me fix it for you.
Hokage strode closer with his long legs.
With a look of shock and exasperation, Guest spoke up.
Huh? Why are you just barging into my room? Go away! Don't come in here!
