One lonely, gloomy fifth-grade girl is the target of her classmates' relentless bullying and teasing—that is, until a new kid arrives on the scene. Friendly Takada is as clueless as he is well-meaning, but somehow he possesses the magic ability to start drawing "Grim Reaper" Nishimura out of her shell. As the elementary schoolers experience all the fun of a childhood summer together—from going to the pool to picking sunflowers to watching fireworks—an unusual friendship blossoms!

In his past life, he was known as Demon Lord Varvatos, an all-powerful magic user and ruler. But he was lonely after the loss of his friends and loved ones during his rise to power, so in his dying moments, Varvatos cast a reincarnation spell so that he'd get a second chance at just being a normal guy. At first it looks like that's going to work – he's reborn thousands of years later as villager Ard. Unfortunately for him, his memories are still intact and he's not aware just how much has been lost over the time he spent not existing, and it looks like that's going to cost him his normal life.

Puberty Syndrome—a rumored, mysterious syndrome that only affects those in their puberty. For example, a bunny girl suddenly appeared in front of Sakuta Azusagawa.

In the course of revealing the mystery behind this phenomenon, Sakuta begins to explore his feelings towards Mai. Set in a city where the skies and seas shine, Sakuta unfolds the meaning behind his bizarre encounters on women with the said syndrome.
