The story focuses on the 16-year-old Protagonist after he is transferred to Shujin High School in Tokyo. Staying with friends of his parents, he meets up with two fellow students, problem child Ryuuji Sakamoto and withdrawn Ann Takamaki, and a talking, shape-shifting cat-like creature known as Morgana. During his time there, feeling suppressed by their environment, the four form a group known as the "Phantom Thieves," working together to carry out heists and encountering mysterious phenomena along the way.

The Phantom Thieves were successful in reforming the heart of Masayoshi Shido, the politician behind all of the disturbing cases. Yet, the public’s response sharply differed from what they had expected. To correct the corruption of society and to achieve the justice they strongly believe in, Ren and the Phantom Thieves embark on their final battle. Source: Crunchyroll
