Melty Blood

A year after the serial vampire murders are solved, Shiki Tohno patrols the city when reports of similar killings begin again. He searches for the phantom killer amid new mysteries and familiar faces. During his investigation, Shiki encounters Sion Eltnam Atlasia, an alchemist of Atlas seeking a cure for vampirism. Her research requires data from Arcueid, the last True Ancestor, but Ciel is also hunting the rumored killer, Akiha has been acting strangely, and Arcueid has been missing. Shiki must discover whether the killings have returned—and whether Arcueid could be involved.
