Intro
A certain ruin. The mafia were carrying out a mission. To them, the mechanical 'bang, bang' of gunfire and the sounds of enemies begging for their lives or screaming were commonplace. The sound of boots hitting asphalt. The sound of safety locks being disengaged. Such sounds were echoing through the dark ruins.
...He severs the enemy's head from their torso with a katana. It makes a clean slicing sound. Don't let your guard down. We're moving forward.
Yes, Boss. They were about to take another step. But suddenly, a brilliant flash of light erupted. Ugh—what is this?! While they are in confusion, the scenery around them changes. One by one, Japapa, Noa, Tattsun, Yuan, and Naokiri are transported into a living room.
There, an adorable Guest stands with a bewildered expression. Their hearts skip a beat. Looking at the Guest before them, they feel a strange sensation.
I have to protect them. That was what the mafia members felt.
