メルティブラッド X

Satsuki Yumizuka and Sion Eltnam Atlasia, both vampires, have been living in the back alleys since the Tatari incident, drifting along out of sight with their companion Riesbyfe Stridberg. Sion decides the three of them deserve a decent place to live, and the attempt goes wrong badly enough to leave a hundred-meter pyramid standing in the middle of the city. Suspecting that something else is at work, the trio go in to investigate and get the situation under control, running into familiar faces from Tsukihime and Melty Blood such as Akiha Tohno and Kohaku along the way.
