Kamiki Kuroto, known as "Kuro-chan," has a close online friend.

This person, called "Gori-san," is a strong female gamer in both fighting games and FPS. She is also a high school senior, one year older than Kuroto.

Gori-san is generally polite and a kind, good person. However, only when playing against Kuroto does she trash talk freely.

Kuroto, for his part, would admire Gori-san's skill while enjoyably returning her taunts.

Kuroto consults Gori-san—who, despite everything, is his closest female friend—about his romantic feelings for a senior he's recently taken an interest in――.
