Episode 02 covers the introduction of Tsukai, Makoto, and Ito, as well as the arrival of a new teacher, Minamino Youko. Meanwhile, the threat of the Kamakura Mad Dog's return looms closer.
A few side notes. I was quite pleased they kept Saejima's infamous pencil nose attack. Just makes him more badass (here's to hoping for an Ino-Head Gargoyle adaptation someday). Meanwhile, Kunihiko Ida, who played Teshigawara in the '98 version of the GTO Live Action series, cameos as the principal of Tsujido High.
