Seishun Buta Yarou wa Santa Claus no Yume wo Minai

Sakuta Azusagawa has finished high school and entered university alongside his girlfriend, actress Mai Sakurajima, but Puberty Syndrome has not stayed behind with his school days. Off campus he sees a girl dressed as an out-of-season miniskirt Santa, and she greets him with a question painfully familiar from his past: 'So, you can see me?'

She calls herself Toko Kirishima and claims to give Puberty Syndrome to others. At the same time, prophetic dreams, an anonymous online singer, and strange incidents begin spreading through social media. Sakuta searches for the connection, only to learn that university has not made life any simpler and unsettled hearts can still distort reality around him.
