Demonbane

Kurou Daijuuji is poor detective. When he is given the job of finding a powerful grimoire by Ruri Hado, he accepts the money almost immediately. But is he prepared when a cute girl falls on him and claims she is a grimoire?

With the help of Al and Demonbane, Kurou is able to defeat Doctor West. After the battle, Kurou tries to escape from Al but Al won't let him go so easily.

While Al and Kurou work to recover Al's pages, Doctor West is planning for revenge.

Members of Black Lodge's Anticross invade the Hado estate. With the Anticross drawing closer to Ruri, can Kurou and Al make it in time to save her?

It's a day at the beach. Although it seems like paradise for Kurou, Al's jealousy makes it a living nightmare for him. But will that compare to the series of disappearances and what happened to the people?

During a rain storm, Kurou and Al find a girl named Ennea, who's memory has been lost except for her name. She could be the key to finding Nero.

Master Therion initiates Black Lodge's master plan. Will Kurou and Al be able to defend the city from this new threat?

With Al gone, Kurou can no longer pilot Demonbane. When all seems lost, an old enemy reappears... but he's here to help. But will it be enough to stop Black Lodge?

Claudius has come to get revenge on Kurou for Caligula's death. Can Kurou and Elsa stop him?

With Claudius defeated, peace seems to have returned... That is until Tiberius arrives with Ruri as his prisoner. Could the return of a dear friend turn the tables of the battle?

Kurou and Al head towards the now dormant Black Lodge Base. Upon entering the base they are confronted by a stronger Augustus...

Kurou prepares to enter the gate for the final battle. What he isn't prepared for is Al wanting to break their contract and head through the gate alone. Will Kurou allow her to do this?
