Kokoro Connect centers around five high school students who form a club called the Student Cultural Society because they don't fit into any existing ones.
Their seemingly normal school life takes a bizarre turn when they begin experiencing strange supernatural phenomena, starting with random body swaps.
These incidents force them to confront not only the strangeness of their situation, but also their own vulnerabilities and hidden aspects of their personalities.
As they navigate these challenges together, the bonds of their friendship are tested, and they must learn to understand and support each other while facing the unknown.
