Melty Blood X

Satsuki Yumizuka, Sion Eltnam Altasia and Riesbyfe Stridberg are outcasts of society, living in the alley, hidden from public eyes. Satsuki and Sion are both vampires and together with Ries, they have been living aimlessly after the events of Tatari. Sion decides to build a robot to help construct decent living quarters for them, but something goes horribly wrong and the robot ends up making a 100 meter pyramid in the middle of the city. Thinking there might be foul play, the trio investigate the pyramid and get things under control. Based on the Tsukihime and Melty Blood games, you will be introduced to other familiar characters like Kohaku and Akiha.
