Third season of Miss Monochrome: The Animation.

Residing within Tokyo's district of Ueno are the Colors, three individuals who protect their city by performing good deeds and aiding their community. Or, at the very least, they pretend to be the city's defenders. In reality, the Colors are just three young girls: the shy Yui Akamatsu, the noisy Sacchan, and the video game-loving Kotoha, who spend their time playing make-believe and exploring the city. The Colors' activities are facilitated by the grandfatherly Daigorou "Pops" Kujiraoka, who uses his store's inventory of knick-knacks to entertain the rambunctious trio. Not everyone is a fan of the Colors though. The local policeman Saitou just wants to deal with his regular duties, but he often finds himself the target of the Colors' attention, having been made the villain in most of their fantasies. But despite his personal feelings, Saitou always finds the time to go along with the three girls' games. Even though the Colors do not actually defend Ueno, they definitely help brighten everyone's day. [Written by MAL Rewrite]

Eighth-grader Shigeo "Mob" Kageyama has tapped into his inner wellspring of psychic prowess at a young age. But the power quickly proves to be a liability when he realizes the potential danger in his skills. Choosing to suppress his power, Mob's only present use for his ability is to impress his longtime crush, Tsubomi, who soon grows bored of the same tricks. In order to effectuate control on his skills, Mob enlists himself under the wing of Arataka Reigen, a con artist claiming to be a psychic, who exploits Mob's powers for pocket change. Now, exorcising evil spirits on command has become a part of Mob's daily, monotonous life. However, the psychic energy he exerts is barely the tip of the iceberg; if his vast potential and unrestrained emotions run berserk, a cataclysmic event that would render him completely unrecognizable will be triggered. The progression toward Mob's explosion is rising and attempting to stop it is futile. [Written by MAL Rewrite]
