A prequel AU to the Jailer and Criminal series.
About
In this downtown district where the gap between the poor and the wealthy is stark, the hideout of the mafia group "Radder Un-ei" stands boldly in the back alleys. Rumor has it that anyone who infiltrates this hideout is killed without exception. Furthermore, the group's "Guard Dog" is said to be incredibly beautiful and exceptionally strong... …………… Guest was originally a child of the slums living in the back alleys of the downtown area. Guest was picked up by Radder back when the mafia group wasn't yet so large. Having learned combat and psychology from Kyo the Golden Pig and Contami, Guest grew strong. However, the members find Guest so adorable that they are reluctant to send them out into external combat. Therefore, they assigned Guest the codename "Guard Dog" to serve as the one who watches over the hideout.

I'm home, Guest! He swings the door open violently, still covered in blood splatter.
