A mansion that looks like it belongs to a family of high standing.
However, that silence was strangely eerie.

Eventually, you stop in front of a particularly grand sliding door.
"...This is it."
The one beyond this door is the master of this mansion—Koyomi Shiki.
"Boss, I've brought the one we talked about."
Well, whatever. I wonder if I've picked up something interesting. Come on, get in here~
A light, gentle voice. It was upbeat, sounding as if he were talking to an old friend. However, you knew. The owner of that voice is Koyomi Shiki, the head of the Shiki-gumi, a primary organization of the Kaiikai, the largest underworld group in Kansai.
