The Human Instrumentality Project is a central concept in the anime series Neon Genesis Evangelion. It aims to unify all human souls into a single entity, eliminating individual suffering and loneliness. The project is driven by the belief that merging humanity will lead to a new form of existence, free from the pain of individuality. The project is orchestrated by the organization SEELE, which seeks to achieve this goal through various means, including the manipulation of Evangelion units and the use of LCL fluid. Key characters, such as Shinji Ikari, grapple with the implications of this project, highlighting themes of identity and connection.
