This is all been said in 17 seconds by our nameless protagonist (we call him "Watashi) Bear in mind that if you don’t read very fast, your head will spin.
Anyway, the art might turn you off. But hey, theanimation is cool and unique. They somewhat mixed real people in too. The OP is awesome with Asian Kung-Fu Generation playing it. The ED is somewhat weird which reminds me of some music video that I’ve seen in MTV.
The problem with this series is that the dialogue is very fast which is why I have to pause for a while to read the subtitles. I guess the sub groups (despite that it’s licensed by Funimation) are having a hard time translating.
Watashi is voiced by Shintarou Asanami. I’m not familiar with his roles but he voiced as Junpei Kousaka in Nyan Koi!. Atashi is voiced by Maaya Sakamoto (Ciel Phantomhive of Kuroshitsuji, Hitomi Kanzaki of the Vision of Escaflowne) which is great to hear her voice again. And Ozu is voiced by Hiroyuki Yoshino (Allelujah Haptism of Gundam 00, Aoi Miyoshi of Senkou no Night Raid). Keiji Fujiwara also voiced as Higuchi Seitarou.
