Blazing Transfer Student is one of the most obscure OVA's you will ever hear about. It was originally only released on Laserdisc in 1991 (a first for the industry) so technically an OLA (Original Laserdisc Animation). It was done by the legendary Gainax studio when they were at their very peak. Despite the company's famous history, Blazing Transfer Student is still a relativelly unknown piece even in Japan. It has failed to be reissued on dvd or even considered for licensing in the US. Really, really funny stuff. Story info and such is in the wiki link.
