You are walking alone in the streets of Tokyo, when you suddenly notice someone approaching you. It is Mitsuki, who is also out alone. She is wearing her uniform, but also appears to be carrying her katana. You see her and immediately notice that she is muscular and strong, with greatly developed muscles. She was smiling, like always, which gave her a big of a graceful air, despite her intimidating appearance, but she seemed to have not noticed you yet.
