Gestapoko cameing to the school and the headmaster lets get make a special punishment for the student with the worst score at that nights exam. Mayumi Takahashi is doing a test but falls asleep so Toenail Of Satan and Teacher Ben Kiyoshi start punishing her with Gestapoko whipping her but she's saved by Kekko Kamen before her undies come off. Kekko kamen drops some undies belonging to Yuka Chigusa. teacher ben kiyoshi overhears Yuka Chigusa chatting with Mayumi and he sees big toenail at a sexy club with babes saying he found its yuka chigusa's undies they have as he knows all the smells of al the girls undies in the school (good f--k man! that's sick!). he tells big toenail his plan and they compliment eachother on being really purvurted. the next day Big Toenail has an assembly to punish the one who broke the rules by interrupting the punishment. as no one steps up, he has mayumi crucified on a giant swastika w/o a top so her b00bz are showing(oh japan!). shes embarrassed by everyone seeing her perky t-ts and if the rule breaker don't step forward, more clothes come off! which gestapoko does(but stops her skirt from coming off after the undies come off). but yuka steps up to stop it but sez it wasn't her who did it. gestapoko sends her Nazis after her but the real Kekko kamen comes in and busts a55. Teacher ben gets beat with nunchaku and big tonail gets a face full of Kekko kamen krotch.
Here he talks to Big Toenail about Shuwarutsu Negataro and Toenail's plan to use him to beat Kekko kamen even though Shuwarutzu is gay. Toenail tells him no busty babe can resist a big buff muscle man. So he goes off to train. At the end of the ep he comes in and he's really jacked despite it only being like what, 9 hours? But Mayumi Takahashi and Kekko Kamen are more into each other than big buff ben. What is this? Card Captors? everyones either yaoi or yuri!
Here he's mostly in the sidelines with Big Toenail as they comment and cheer for Mizutamari Tsuyokaro. He suggests going after Mayumi Takahashi again st flush out Kekko Kamen again. Later when Mizutamari Tsuyokaro fights Kekko Kamen, He and Toenail show up and lust after her open thigh jump. But whine when Mizutamari Tsuyokaro blocks it with an umbrella. After Kekko Kamen leaves, they string up Yuka Chigusa and Mayumi Takahashi from a tree. He sez he's getting tired of doing stuff to Mayumi and wants to try stuff with Yuka. The chicks complain but he gives em da bird and tells em off. Kekko Kamen shows up again and fights Mizutamari Tsuyokaro but He and Big Toenail say not to ice her as they like seeing her open thigh jump. Kekko Kamen spins her Nunchaku and makes a tornado like its freakin Digimon and blows away Mizutamari Tsuyokaro's umbrella. Then crotches his face. The blows he bad guys away with the tornado seemingly for good. The End.
