A scrupulous vampire happy with his mundane life finds himself perpetually tested by his bored--and very unscrupulous--coworker. Office worker--and 40-year-old virgin--Minoru Sayo lives a simple, if not boring, life. At least he did until the day he was turned into a vampire! Unable to bring himself to drink human blood, he satiates his overwhelming hunger by feasting on cats. But one night, after a disastrous mixer, Minoru is pushed to his limits when his junior colleague passes out drunk, neck exposed, while waiting for the train. Unable to resist, Minoru sneaks a taste, but not all is what it seems with his hapless colleague, and Minoru's mundane life takes yet another unexpected turn!.
