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...
Without Miss Kisara, I am nothing
but a rock on the roadside...
...من دون كيسارا-سان، أنا لا شيء سوى صخرة على جانب الطريق
Ohne dich, Kisara-san,
bin ich so nutzlos wie ’n Stein.
Sin mi Kisara soy
inútil como una piedra.
Sin mi Kisara soy
como un pedrusco inútil.
– Sans toi, je ne suis qu’une larve…
– Capitaine.
Senza Kisara, io non sono altro
 che un inutile scarto...
Sem você, ó, Grande Kisara, eu sou
apenas uma pedra no meio do caminho...
Без вас, госпожа Кисара,
я всё равно что камень на обочине!
