A large-scale power outage hits the heart of Bayron City's Downtown. It was a D Hazard caused by a giant caterpillar-shaped Demonically Possessed. With detailed information on Demon Possession that he obtained from somewhere, Shu decides that this is a job that "must be done" and uses Ayano for insider info to pull strings. As Shu's company is about to win the bidding war at a discount, significant new information about the Demonically Possessed is revealed. Those who took the situation most seriously decided to suspend bidding and expelled Shu from hazard prevention measures.
And now he's the strongest Demon Exterminator
and the only demon-user in this city, huh?
وهو الآن أقوى مبيد شياطين ومستعمل
الشيطان الوحيد في هذه المدينة، صحيح؟
Und heute ist er der
effizienteste Dämonenbekämpfer
Y ahora es el mejor
Exterminador de Demonios
Y ahora es el mejor
Exterminador de Demonios

E agora, ele é o melhor Exterminador da
cidade e o único capaz de usar demônios.
А теперь он стал
сильнейшим охотником на дьяволов
