07-ghost. 9 - Yukino Ichihara

The paths of one evil god, two rival empires, three unlikely bishops and seven brave ghosts converge in the destiny of Teito Klein, a boy who vows to master a powerful artefact known as the Eye of Mikael in order to lay bare the secrets of the world's - and his own - murky past.

Entangled by the Kraut House's corruption, Teito finds himself imprisoned in an icy tomb with a strange girl who he swears he's met before. Learning the dark secrets of Labrador's past is key to surviving the sub-zero garden, but the trail leading to the gentle Seven Ghost's sad last days is anything but a primrose path.
