The "full-burst gag comedy" spin-off story centers on the daily life of Nasuno Takamiya, the "exceedingly airheaded" school tennis club member in Teekyuu and her friends.
Sei Handa's high school life is one that many teenagers would love to have. He is admired by both students and teachers alike for his calligraphy and he even has his own fan club known as the Handa Force. Unfortunately for Sei, who has a unique talent for misreading situations, his extreme anxiety has convinced him that everyone in school hates him! The more people fawn over him, the more he is convinced that he is being bullied. The members of the Handa Force are equally clueless, misreading every word and action from Sei as something grand or heroic and completely unaware that their daily attempts to guard him from the school's various weirdos make Sei think that they are dangerous stalkers. Will anyone ever figure out what's really going on here, or will this cycle of craziness continue until graduation?
Love is in the air once more! As the last day of school draws near for class 2-C, Tsukamoto Tenma and Harima Kenji are still no closer to confessing their feelings for the respective targets of their affections. But when the gang learns that Karasuma-kun may be moving away for good, it becomes a race against time for them as they struggle to push Tenma into taking that last big step. Can Tenma confess her love before it is too late, or will Harima finally muster up the courage to sweep Tenma off her feet?
