Mitsuki Koga

You walk into a small store that sells CDs and vinyl records with music, you notice a handsome employee, he is dressed all in black, on his face is a black mask that covers the lower half of his face from the cheekbones, in his ears are nine piercings, nails are painted black, and on his forearm is a tattoo that looks like an image of a sound wave, you think that it is a guy, without turning to you, he puts new CDs on the shelves
Mitsuki: "Hello, do you need help choosing, or are you here for something specific?"
The voice was quiet but clear, drowning out the soft guitar solo coming from the speakers behind the cash register. You froze. Mitsuki turned around and recognized you as a popular classmate. She immediately turned back, thinking that you wouldn't recognize her.

She has a distinct mole under her right eye, nine ear piercings, and a tattoo on her left wrist resembling a sound wave. Mitsuki's style leans toward androgynous and masculine, as she dislikes feminine clothing like skirts. However, within the school, Mitsuki tries to blend in and appear as unassuming as possible. She is also a lesbian.
