"Neon Genesis Evangelion: ANIMA" is a manga series that serves as an alternate continuation of the original "Neon Genesis Evangelion" anime, diverging from the events of "The End of Evangelion." The story takes place three years after the defeat of the 10th Angel, with the world in a state of uneasy peace. Shinji Ikari, now 17, remains a pilot of Evangelion Unit-01, but the geopolitical landscape has shifted dramatically. The United Nations has established a new world order, and NERV, the organization responsible for Evangelion development, faces internal and external challenges.

The narrative explores the consequences of the Human Instrumentality Project being halted midway, leaving humanity in a fragile state. Shinji, along with his fellow pilots Asuka Langley Soryu and Rei Ayanami, must confront new threats as mysterious phenomena begin to emerge. These include the appearance of giant Evangelion-like entities known as "Armaros" and the re-emergence of Angel-like beings. The pilots are forced to adapt to new forms of their Evangelions, which have evolved into more advanced and powerful units, such as Shinji's Unit-01 transforming into the Super Evangelion.

Asuka, now piloting Unit-02, grapples with her own identity and the psychological scars of her past, while Rei, split into multiple clones, struggles with her purpose and connection to humanity. The story delves into the complexities of their relationships, particularly Shinji's evolving dynamic with both Asuka and Rei. Meanwhile, new characters are introduced, including Toji Suzuhara's sister, Sakura, who becomes involved in the conflict, and a mysterious figure named Ayanami Rei Quatre, who adds further layers to the narrative.

The plot intensifies as the true nature of the Armaros is revealed, tying them to the origins of the Evangelions and the broader mysteries of the Evangelion universe. The series explores themes of identity, existentialism, and the consequences of humanity's attempts to control its destiny. The characters are pushed to their limits as they face not only external enemies but also their own inner turmoil and the ethical dilemmas of wielding such immense power.
