Out loveable reverse vampire Karin can't help it: classmate and coworker Kenta's unhappiness triggers her bloodlust. Although she's learned to control her urges around Kenta, when her excess blood becomes too much to handle, even Kenta isn't safe!
Karin just doesn't know how to interact with Kenta anymore, which makes for an unusually awkward second term of school. And when upperclassman Ayaha Ougimachi appears on the scene, things become more and more strange...
