Katte ni Kaizou

Katsu Kaizou is a former student of the Genius Cram School (Tensai Juku), but his childhood friend Natori Umi accidentally turns him into an idiot (and possibly insane) by injuring his head.

Kaizou's crazy ideas cause an explosion that forced the Genius Cram School to shut down.

Even years later when Kaizou is in high school, his former classmates have come looking for payback.

So, Kaizou, Umi, and the other members of their high school science club are in for quite surreal situations.

Note: The first and third episodes received a live webcast limited to 5000 viewers on NicoNico Douga which preceded their BD/DVD release dates by two days.
