A mind reader who can see every move coming before you make it forces the show to think faster than it ever has. Nao and Yuu can't fight what they can't hide from, can't plan around what's already been seen. The OVA compresses everything Charlotte does well, the supernatural problem-solving, the character chemistry under pressure, the moment where powers stop being advantages and become prisons, into a single perfect gear that clicks.

A clairvoyant kid, Takehito Kumagami, points his friends toward another child with supernatural powers: Iori Sekiguchi, a girl who reads minds. The catch is that her power makes her almost impossible to pin down. Every approach they plan, she already knows about it before they make a move. Picked by the club to take on the case, Nao Tomori and Yuu Otosaka have to find some way around her unusual ability before time runs out. This single OVA episode mixes comedy, drama and supernatural elements as the pair try to outwit someone who can hear their thoughts coming.
