An animated spin-off of the TV drama Densha Otoko (Trainman). In the drama, Itoh Atsushi plays otaku Yamada, whose major passion in life is the Mina anime, a cutesy busty heroine with floppy rabbit ears and carrots sprouting from her behind. Mina is a character tribute to the Daicon Animation done by GAINAX, where a similar unnamed bunny girl emerged. Densha Otoko went on to have an opening that used sequences from the Daicon Animation.
