Goshintou Series

The delicate edge of a perfect sword can slice through flesh without a sound… but only the rarest weapon houses an apparition-battling spirit, too! Two warriors – one naive and one experienced – must wield their special blades with great care in order to conquer their opponents. Elsewhere, a clumsy young scientist and a cautious priest feel the sharp pangs of desire...and an ancient monster lashes out for the one he loves. Will the fates of these men fuse together powerfully, or will they splinter into nothingness? (Source: Juné)
