Ruri Hijiribe''s been injured by her stalker, whose delusions seem to only grow stronger by the day. With a warped plan to inflict harm on the people around her, the stalker sets his sights on his first target--the black rider''s beloved underground doctor, Shinya Kishitani! Holding a wounded Shinya in her arms, she''s so furious she loses her head--well, despite having no head, that is.

Seems Ikebukuro is as hectic as always with these shady characters lurking in the shadows!
