Shu is always in trouble with money but manages to live thanks to the support given by his ex-girlfriend Ayano and the ever-devoted Kisara. The same goes for his job as a PMC. With Ayano's cooperation, Shu won a bidding war at a discounted price to participate in the "D Hazard" prevention operation that occurred in a casino. At the scene of the demon extermination, he planned to rely on Kisara's demonic powers, but she is nowhere to be found due to the money situation ruining her mood. As a last resort, he works with Ayano's leading, major PMC and confronts the Demon, but bit by bit, the battle becomes something suspicious...
If you really put your heart into it, as a genius,
you'll never lose against anyone!
!إن عقدت عزمك بالفعل، بما أنّك عبقري، فلن تخسر أمام أحد أبدًا
Eres un genio, así que si te esfuerzas,
no hay nadie que pueda ganarte.
Eres un genio, así que si te esfuerzas,
no puede ganarte nadie.
Sei un genio e quando fai sul serio,
 nulla può sbarrarti la strada.
Quando se dedica de verdade,
você é um gênio incomparável.
Настоящий гений — если берёшься
за дело всерьёз, никому не уступишь!
