Mythical beast becomes the lesbian maid of a possibly asexual japanese salarywoman.
But it's still a damn funny series.
Flat-chested schoolgirl swings gigantic scythe around on behalf of the Grim Reaper, along with a total idiot and his ninja-weapon partner, and the Grim Reaper's son who has an unhealthy obsession with symmetry. Oh, and did I mention the goddamn sword?
