Based on a hentai videogame, Mizuiro
tells the story of two girls who like Kenji a lot. The first episode covers Yuki,
Kenji's younger sister. Her obsession with her brother makes her sad, especially
considering they're brother and sister, despite not really being blood related.
The second episode goes through clumsy Hiyori's game ending, where she appears
out of Kenji's dresser - naked and ghost-like. While the girls are cute enough,
the more serious story elements aren't worked out convincingly enough. It doesn't
help that the art and animation are bog standard, and that the music is the usual
hentai drek. The uninspired writing and lackluster pacing don't make things any
better. You're much better off watching the non-hentai OVA series released a year
later.
