Serial middle school girl murderer Girl A escapes from the facility where she's being held.
Mirai's group deduces that in order to lure out other God candidates, Metropoliman gave her Wings and an Arrow so she could escape.
Mira despises Metropoliman's willingness to play dirty and do whatever it takes to become the next God. Eventually the first victim is found at the Grand Tower in the city, and the situation rapidly worsens. Mirai's group chooses to act to stop Girl A's murders.
Which means we have an opportunity 
to shoot Metropoliman with a Red Arrow.
مما يعني أنّ لدينا فرصة
إصابته بالسهم الأحمر
Das gibt uns die Gelegenheit,
C’est donc une chance inespérée
de l’atteindre avec une flèche rouge !
