Puberty Syndrome...
A bizarre phenomenon rumored to be triggered by an unstable mental state.

After encountering various girls going through Puberty Syndrome, Azusagawa Sakuta's high school days have come to a close, and he is now a university student. He enrolls at a university in Kanazawa-hakkei alongside his girlfriend Sakurajima Mai, a nationally famed actress. Off campus, he stumbles upon an out-of-season miniskirt Santa.

"I'm surprised. So, you can see me."

This is a phrase he's heard somewhere before. This miniskirt Santa, who claims to be gifting Puberty Syndrome to people, tells Sakuta...

"My name... is Kirishima Toko."

Precognitive dreams, an anonymous online singer, poltergeists buzzing on social media... A mysterious tale with enigmatic phenomenons surrounding girls with wavering hearts starts again.
Puberty continues...
