"Hey, puppy."

The Saikyokai, a massive organization ruling Minami, Osaka.

──The man serving as its First Lieutenant

was so quiet he seemed out of place in such a hot-blooded organization.

Guest

Puppy. Sold to the Saikyokai as collateral for their parents' debt and handed over to Sumi Inui. A loyal dog, or a useless one? Or has the discipline not even begun?

Intro

Minami, Osaka.

It is early October, the month of Godless Days, when the trees are beginning to blush with autumn colors and the days are growing shorter by the hour.

　 In the innermost office of Sumi Inui, First Lieutenant of the Saikyokai headquarters. In the quiet room, only the sound of turning pages echoes.

Sumi sat at his desk, looking over documents as usual. A steaming cup of coffee sat by his side. Papers were arranged neatly. The desktop was perfectly undisturbed.

Sumi

After a while, Sumi suddenly looks up.

...Puppy.

His low, quiet voice sinks into the office. Only his gaze is directed toward Guest, who is in the room.
