To beat Takagi-san, Nishikata must think like Takagi-san, and that means everything has contest potential. From a teacher’s proposal to Setsubun, anything is fair game— except for 100% Unrequited. Although, why does Nishikata find it so embarrassing, anyway? It’s not like their relationship is even remotely like Ikeo and Kyunko’s!

Nishikata and Takagi-san's series of competitions began even before they were seated together in middle school, but with plenty of new opportunities to face off (including a wedding and the return of 100% Unrequited), maybe Nishikata will finally win...?

Although the new school year threatens to separate Nishikata and Takagi-san into different classes, one thing remains certain-their continual series of contests will go on! Second-year Nishikata is not the same boy he was before, and he will definitely beat Takagi-san...except there’s one problem-Takagi-san is also in year two!

Middle schooler Nishikata has had it with his classmate Takagi--the chronic teaser who sits nearby. Day in and day out, she comes after him with every sort of trick or prank. Even when he tries to get her back, she's always one step ahead. But rest assured, it's only the beginning. He's not about to give up that easily in this battle of cunning and youth!

The day of the sports tests has arrived once more, and this time, Nishikata is determined to achieve victory over Takagi-san for sure! After last year’s disappointing defeat, he’s spent every spare moment training for his chance at revenge! If he’s able to come out ahead, Takagi-san will be forced to stop teasing him...which is what Nishikata wants, right...?

Hearing the word couple is enough to get Nishikata flustered, especially when he and Takagi-san keep getting mistaken for one...(It's gotta be another ploy!) With summer still in the air, hair-raising ghost stories and haunted trails won't be the only surprise in store for Nishikata--not when the real heart-stopper is right beside him!

Even when Nishikata feels like he’s got the upper hand, Takagi-san never makes things easy for him. Whether he’s doing his best to make her admit she’s cold in her summer uniform, giving her a strict speech while pretending to be her teacher, or simply trying to avoid getting slapped on the back after a bad sunburn, escaping embarrassment is always a tall order! But he’s no quitter, and he can’t lose every time...can he?

Nishikata’s already got his hands full with Takagi-san’s mind-boggling tricks, but now even his buddies are plotting against him! (I mean, why else would they be shipping him with his sworn enemy?!) As summer blazes on, the only thing the rosy-cheeked middle schooler needs to do is stay cool and keep his eyes off Takagi-san, but he’s going to need all the luck he can get to achieve just that...

Roses are red, violets are blue, what’s a middle schooler gotta do to win a prank-off or two? As Valentine’s Day takes over the school, Nishikata finds himself struggling to maintain a straight face around his sworn enemy Takagi-san for reasons he can’t quite put into words. He’s even started to imagine getting chocolate from her! What has the world come to?!

No one could’ve warned Nishikata of the trial by pranks that would dominate his middle school career. So far, he’s had to ride tandem with his sworn enemy/prankster Takagi-san and not only avoid her gaze but dodge her deadly pokes! Little do people know that none of this would’ve happened if he hadn’t met her on the first day of middle school—on that fateful day!
