After trumpets of the apocalypse proclaim the fall of humanity, vampires arise
from the shadows to rule the earth. Yuichiro wants just one thing—to get revenge
by killing each and every vampire.
Yuichiro has no memory of his terrifying but temporary transformation into a
one-winged monster during the battle for Shinjuku. The widely feared leaders of
the Japanese Imperial Demon Army, however, take note of his squad's unusual
talent. Despite the unwanted attention, Yuichiro's resolve to save Mika from the
vampires crystallizes as his real training in demon possession and manifestation
begins.
