Nobody talks about this one. Sawashiro Miyuki voices the entire cast, every character, every gender, every creature, and instead of being a gimmick that wears thin in five minutes, it becomes the actual joke engine of the show. The comedy lands because you're constantly catching the seiyuu's range, watching her flip between voices so fast and so seamlessly that the absurdity of watching one person perform an entire world becomes the funniest thing on screen.
A single voice actor becomes an entire cast. Sawashiro Miyuki plays every character in this comedy, male and female, human and non-human alike. Made as a collaboration between the studio ufotable and manga creator Yagami Yuu, the 2009 ONA ran for 26 episodes on BeeTV, a television service for mobile phones. Its standout feature is that one performer supplies every voice, which makes it a curiosity for anyone interested in voice acting.
