Kanan is a demon who descends upon the human world with one goal: to feast on the sweetest delicacy of all—young human souls. Disguised as a high schooler, she sets her sights on her first target, an unassuming boy named Youji Kyougi. But just as she prepares to claim her meal, things take a very unexpected turn. Instead of devouring him, Kanan ends up forming a "romantic contract" with Youji. For someone who's lived for millennia without experiencing love, navigating high school romance proves more terrifying than any hunt. Between awkward dates, hand-holding mishaps, and feelings she can't quite name, the once-proud demon finds herself flustered at every turn. A supernatural romcom about a lovestruck demon and the boy who was supposed to be her prey—sweet, chaotic, and full of firsts. (Source: MAL News)

Meet Takuya Seo, an otaku who sits behind the popular gals in class, Ijichi and Amane. Since they're people from different "castes," you wouldn't expect them to have much in common.

She says she's not a fan, but her familiarity with the series suggests otherwise. Could she be...a fellow geek?! (Source: Yen Press)

As the year nears its end, the time for final exams arrives at Rigarden Magical Academy. Despite being the only student without any magic aptitude, Will Serfort aims to score perfect grades in every subject, which would allow him to ascend to the Wizard's Tower and reunite with his childhood friend, Elfaria Albis Serfort. However, Will's hard work comes tumbling down when he fails the very last, biased exam, disqualifying him from entering the Wizard's Tower. Meanwhile, Elfaria and the other Magia Vander—the five most powerful mages—perform the annual ritual that protects their world from the dangerous Celestial Hosts. As the ritual temporarily leaves the Magia Vander drained of magic, a large army of monsters suddenly appears and begins attacking mages and civilians alike. To make matters worse, the mages are unable to hold off the invasion due to the monsters' special weaponry that nullifies their magic. Refusing to let the world end in despair, Will and his masterful swordsmanship quickly become a cornerstone in stopping the attack. [Written by MAL Rewrite]
