Kanna who usually enjoys being at the top of her class is outscored by one point on the first aptitude test of her high school career by the high-level kuudere/low-level dandere Yuu. Unlike Kanna, Yuu is naturally talented and couldn't care less about getting high scores, so she throws away her test immediately after after getting it. This incredibly bothers Kanna, who then in front of the class, scolds Yuu for throwing away her "symbol of how hard she worked". This gesture of kindness(??) causes Yuu to fall for Kanna. And of course, all unbeknownst to Kanna, who's all about herself anyway.

When discussing conquest, Il Palazzo's motto would most likely be "start small." ACROSS, a group devoted to carrying out and accomplishing the ideals of absent-minded yet bishounen Il Palazzo, feels that the first step in conquering the entire planet would be conquering a single city. This city just so happens to be Fukuoka, where our story takes place.
Along with the "help" of overly energetic Excel and oft-dead Hyatt, the leader (and self-proclaimed Lord) of ACROSS strives to make the planet better through domination. Elgala, whose personality constantly irritates Excel, joins ACROSS in volume 8.
Meanwhile, Dr. Kabapu (the Dr. part is very important!!) starts the Department of City Security, in hopes of protecting the city from people who would want to conquer it. Watanabe, Iwata, and Sumiyoshi, three slackers, join his staff, and are later joined by Misaki Matsuya, who missed the introductory staff meeting.
Helping Dr. Kabapu is Professor Shiouji, the most brilliant scientific mind in all of Fukuoka (who just so happens to be a VERY blatant pedophile). The professor creates Ropponmatsu, an android modeled after a female human. After she explodes in a bomb crisis (accidentally caused by Excel and Hyatt), he creates a second model more to his tastes (if you know what I mean).
With intelligent humor that (most of the time) is anything BUT random, well developed characters, an amazing storyline, and actual action, this isn't like the anime, and that's not a bad thing.

This is a walkthrough of life (a shitty videogame)!

Life is a bad video game. This cliche phrase is, sadly, a reality.

However, life doesn’t have simple, easy rules. What it does have is irrationality and inequality. The strong say that they have a lot of freedom, but the weak have no choice but to live an overwhelmingly disadvantaged lifestyle.

Therefore, it’s a shit game. There’s no mistake because I, the best gamer in Japan, declare it to be shit.

— However, that person, who is on the same level as me, goes around saying “Life is a great game.”

The school’s perfect, strong-willed heroine, Hinami Aoi. Furthermore, “I’ll teach you the rules of life (game)”?

…Normally, I wouldn’t believe in those words. However, Hinami Aoi is a character that doesn’t even fit in a normal frame at all!

From the winner of the 10th Shogakukan Light Novel Award for Excellence. A jaku-chara takes on life’s strategy guide, but with instruction from a bishoujo!

An excellent and very educational series. About a newlywed couple who are virgins and their comedic ups and downs in learning how to have sex. Not really a hentai, though there are scenes which can be called hentai. Tastefully rendered taboo themes. A funny "how to" guide for sex illiterate and experts.
