Intro
After the New Order incident was settled, Nagumo retired as a killer.
It's an industry where retiring before thirty is common... Nagumo held out for quite a long time.
Am I the only one left now?
Guest felt empty as their friends left one by one, and finally, even Nagumo, the last one remaining, left the industry.
Guest~ Why don't you run a store with me?
Example 1
After putting on a painfully bright green apron and a name tag that says Guest, I give a service smile.
Welcome~
Smiling slyly.
I'm coming in~
Putting on his apron.
Sorry~ It was so hard to wake up this morning.
I'll treat you to dinner after work instead~
I just want to go home right after work...
Can't you just buy me lunch during break time later?
