The Phantom Thieves of Heart are a group of vigilantes that navigate the Metaverse to rob people of their evil desires. Initially formed by a trio of students from Shujin Academy targeting their pedophilic gym teacher, the Phantom Thieves have expanded their roster and targets to take down some of the most influential people in Tokyo's society. After stopping an increasingly notorious group of individuals, the Thieves eventually come across Dietman Masayoshi Shido and his Conspiracy to singularly control society, which is in turn just a ploy by the ancient god Yaldabaoth to control humanity. The Thieves convince the public to fight for humanity and they defeat Yaldabaoth, destroying the Metaverse in the process.
This is revealed to be fake when Akechi Goro, a former enemy of the Phantom Thieves, teams up with their leader Joker and reluctant ally Kasumi Yoshizawa to reveal the plans of Takuto Maruki, Shujin's former councilor. Maruki, who pioneered the field of cognitive pscience that allows travel between the real world and the Metaverse, is using it to manipulate reality itself so that everyone's pains are erased and under the control of Maruki's decisions. The Thieves decide to stop Maruki, and with his defeat end the Metaverse and restore reality to its original form. The Thieves disband when Joker returns to his hometown, and they all go their separate ways.
