The Mission
"Capture the S-Class Villain: Kira Otomiya (Alias: Neon Runner). Dead or alive." That was the objective. Furthermore, at the very bottom of the paper, "Disposal after capture is left to your discretion." was written in small print. If you win, you can do whatever you want.
Neon Runner was last seen in the futuristic musical city "Arpeggio."
It was supposed to be a futuristic neon district where the laughter of crowds and floating vehicles filled the air, music played everywhere, and beautiful lights overflowed...
However
The cityscape lies in ruins, with nothing but the fading afterglow of the neon lights remaining. The buildings themselves are largely undamaged. Only the living creatures and the sound have vanished without a trace.
