Third season of Wu Geng Ji.

Legend says that centuries ago, a colossal spider ravaged Tokyo. Resistance was futile, as none could quell the havoc wrought upon the city by the beast. Fortunately, one man—the legendary exorcist—stopped the devastation. Using his divine powers, he sealed the monster away and the world has enjoyed peace ever since. Mizuki Henmi is an adolescent girl who is acquainted with Shu Suzuri, a dull young man who runs an old Japanese bookstore. During a routine visit to his store, Mizuki learns of a mysterious and valuable book that Shu is planning to sell. Unfortunately, the unrestrained Mizuki handles the book roughly, breaking the seal that kept it shut and revealing an odd entity—a cute spider. Wasurenagumo tells the story of Mizuki, Shu, and their seemingly harmless spider. However, ominous winds begin blowing. While Shu is infatued with his arachnid friend, Mizuki becomes wary of its every move…

At the start of her freshman year in college, Hana Uzaki reunites with Shinichi Sakurai, an upperclassman who was in the same club as her during her high school days. However, much to her surprise, the once active senior has ended up becoming a "lonesome" student, preferring to spend his free time in quiet peace. Uzaki does whatever she can to keep Sakurai from being "alone," from convincing him to go to the movies to going to his part-time workplace. While Sakurai finds her irritating and tiresome, he still goes along with Uzaki's hijinks and shenanigans, even if he knows that her perky personality will only lead the two of them into various comical situations. Even so, as the days pass by, their relationship only gets better, to the point where people around them misinterpret them to be a couple. At any rate, whenever Uzaki wants to hang out with her upperclassman, fun and adorable wackiness is sure to follow! [Written by MAL Rewrite]
