Bloody Cross, Volume 7 (Bloody Cross #30-35)

Nao and Hinata quickly realize that infiltrating Kamuhaburi will be far more difficult than spying on Tsuzuki or even Arcana. Their first objective is to find a way to contact Izumi - and when they do, they aren't happy with what they hear. Izumi wants to recover not only Arcana's stolen relics, but all of the relics Kamuhaburi has collected as well. But there's more he's not telling them, and even more their Kamuhaburi guide, Kanade, is holding back. With no one they can trust, the squabbling spies must work together to complete their mission or be trapped inside forever!
