Soul Eater Not! (ソウルイーターノット! Sōru Ītā Notto!) is a spin-off prequel of the main series focusing on a freshman transfer student named Tsugumi Harudori, who befriends two other Meisters named Meme Tatane and Anya Hepburn as three take part in the "NOT" meaning the Normally Overcome Target class at DWMA. She wants to learn how to control her powers in order to overcome her difficulties to have a normal life.
The story and pace of Not! is drastically different from that of Soul Eater's but instead having the focus on Maka Albarn, protagonist of the parent series, it is leaded by Tsugumi Harudori, a Japanese, 14 year old girl who finds herself with the ability of a magic Demon Weapon who then transfers to the American Shibusen or Death Weapon Meister Academy campus in order to control her powers. Tsugumi finds herself with two friends named Meme Tatane and Anya Hepburn, these girls eventually become candidates to be the single meister of Tsugumi and along the way, Tsugumi occausionally runs into characters of the first Soul Eater such as the as forementioned Maka Albarn and her partner, Soul Eater, or Black☆Star and Tsubaki Nakatsukasa. Some characters from Soul Eater actually become series regulars like Kim Diehl, and Sidney "Sid" Barret. Throughout the series, the young thrush learns the importance of friendship and bonds as well as knowing her own strength and her self-worth; It's a cruel but wonderful world.
According to Atsushi Ōkubo, Soul Eater NOT! takes place a year before the prologues time frames, which are the first three chapters and which introduce many of the main characters. A common misconception is that Soul Eater NOT! takes place a year before Soul Eater.
Keep in mind that the anime of both Soul Eater and Soul Eater NOT! do not follow the manga's official stories, change minor details, deviate from the manga, and can be inconsistent.
