Hina’s new high school is strange to say the least. She moves back to her old home town only to find that the high school is run by two opposing factors, and students identify themselves based on the color of their school uniforms: Black for the followers of the loud, violent Nishizaki, and white for the followers of quiet, clean-freak Isshiki. And then there are the “grays,“ who wear street clothes. Hina finds herself stuck between the leaders of the two factions, and it seems to be turning violent.
As one might guess from the girly art and the Ribon publisher, the plot develops a romance element pretty early on in the series. There’s a love square involved among the leaders of the groups. Who will Hina choose?

“Community News,“ by Saitou Emi and the Heisei Community Committee, is a 4-panel manga strip.
In “P=NP?,“ by Taroh Amaguri, Eriko wonders if Shino is just going out with her so that Eriko will do her homework for her.
“Ririka and Chihiro’s Exciting Life,“ by Otokuni Momo, is another 4-panel manga strip.
“Salyune,“ by Hashimoto Ikumi and Sarashina Mizuho, is a short, sweet science fiction story.
“Girlish Delights,“ by Mitose Noriko, is about a shop full of things that supposedly only girls understand.
In “A Cruel God,“ by Takano Youko and Shouya Toko, Kei is interested in a woman at the gym. Imagine her surprise when she sees her in a lesbian bar!

There are six members of the boy’s ping pong club. Two are relatively normal; however, the other four consist of an aspiring sexual deviant, two perverts, and a guy with lethal B.O. Add in a cantakerous girl as a manager, and you have the entire crew.
This series pushes the boundaries of good taste beyond anything the western world has experienced, yet somehow manages to remain vaguely charming. The antics of the ping pong club includes one member’s trademark “Protruding Pecker Serve,“ molesting cross-dressing members, and the infamous “Turtle Sequence,“ which is much too horrifying to describe.
NOTE: Full frontal nudity and tasteless jokes abound.
