[1] It stars Tsumabuki Satoshi as Tojo, Christian Storms as Mr. Robert, Ayase Haruka as Hoshi, and Arai Hirofumi as Itadaki.
The action in the classroom is centered on: Tojo, who is not paying attention, wakes up when he realizes a girls' gym class is running the hurdles outside.
Using the five-stroke Chinese character "正", Tojo keeps a running tally of when the girls readjust their buruma (literally "bloomers", roughly the same as the spankies cheerleaders and female volleyball players wear).
After Mr. Robert looks out the window, who is astonished by the girls' beauty at the first sight, he throws Tojo out of class and tells him in English and Japanese to "get out in the hall".
The girls' gym class comes back into the building and Hoshi flirtatiously confronts Tojo, who sprouts a nosebleed when he sees her adjust her bloomers.
