Soul Eater NOT! is a spin-off and side story that takes place one year prior to the events of the original Soul Eater. At the Death Weapon Meister Academy, humans born with the power to transform into weapons and those with the power to wield these weapons (Meisters) train to hone their natural talent. The characters of the main series are enrolled in the Especially Advantaged Talent class, where they train to become warriors of justice capable of defeating what threats prey on innocent lives—or even the entire world. Other students at the DWMA are less talented. Members of the Normally Overcome Target class focus less on being warriors of justice and more on controlling their powers so they don't hurt themselves or anyone around them. Tsugumi Harudori, a new halberd-transforming student, meets Meisters Meme Tatane and Anya Hepburn and quickly grows indecisive about which of the two new friends should be her partner. As they learn to use these powers and settle in, their lives as everyday students will be far from normal.

In a world on the verge of a great disaster that began five years ago, heroes who, with the help of a device called HxEros, use the power of Ecchi (H) and erotic power (Ero) to save the planet from libido-devouring monsters! Enjou Retto and Hoshino Kirara are childhood friends who have drifted apart from each other. One day, they're caught in a battle against a "Censor Bug" that feeds on human's sexual energy to evolve. After successfully taking down the enemy, they join a group of heroes like them, using the erotic power of the HxEROS force to fight off monsters. (Source: MU)
