Seiōdai Sampling Laboratory

Seiōdai Sampling Laboratory (西王大サンプリング研究所) is the place where Shūichirō Ayatsuki worked before he moved to the First Area.

In year 2106, Celica A. Mercury, together with Bloodedge and Mitsuyoshi, arrived here looking for clues for her father's whereabouts. They encountered a Remnant of the Black Beast, which heavily wounded the Beastkin, but it disappeared after touching Celica, and after that Rachel Alucard teleported everyone to the Moonlight Castle.
