In the continent of spooner, sorcerers, who are the continent's aristocrats, have begun to abuse their powers. Under the guidance of Big Momma (their boss) Carrot (who turns into a giant monster every time he's placed under a magic spell), Gateau (a bodybuilder), Marron (a mage), Chocolate and Tira (who can transform into dominatrix's at will) must stop the evil sorcerers from picking on the weak; however, none of them (except maybe Marron) have a clue to what's going on.

When middle school kendo champion Ayumu Tanaka begins his first year in high school, he does not take the expected route of joining the Kendo Club; he signs up for the unofficial Shogi Club instead. His sole motive is falling in love at first sight with Urushi Yaotome—the club's president and only member—and will do anything to get closer to her. However, Ayumu decides not to confess to Urushi until he can beat her in a match of shogi fair and square. Naturally, this self-imposed hurdle is a formidable challenge for Ayumu to overcome, as Urushi is far more experienced at the game and sees through his every strategy. Nevertheless, this does not stop him from praising her looks, her skill, or even her smile, which, coupled with Ayumu's expressionless face and direct approach, makes Urushi constantly blush beet red. Learning more about shogi and the charming player sitting across from him, Ayumu inches toward making his confession with each exciting round they play together—even if it is one pawn at a time!

Death City is home to the famous Death Weapon Meister Academy, a technical academy headed by the Shinigami—Lord Death himself. Its mission: to raise Death Scythes for the Shinigami to wield against the many evils of their fantastical world. These Death Scythes, however, are not made from physical weapons; rather, they are born from human hybrids who have the ability to transform their bodies into Demon Weapons, and only after they have consumed the souls of 99 evil beings and one witch's soul. Soul Eater Evans, a Demon Scythe who only seems to care about what's cool, aims to become a Death Scythe with the help of his straight-laced wielder, or meister, Maka Albarn. The contrasting duo work and study alongside the hot headed Black☆Star and his caring weapon Tsubaki, as well as the Shinigami's own son, Death the Kid, an obsessive-compulsive dual wielder of twin pistols Patty and Liz. Soul Eater follows these students of Shibusen as they take on missions to collect souls and protect the city from the world's threats while working together under the snickering sun to become sounder in mind, body, and soul.

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.
