Natsu no Arashi! - S01

The summer of a boy's fading childhood lingers. Stuck between youth and adulthood, he shares a bond with the ghost of a young woman from World War II. Alongside other spirits of that era, she and her fellow ghosts embark on adventures with their living partners, uncovering secrets and journeying through time thanks to their eerie connection. While he pines for her, his feelings remain unfulfilled-even as his friend, a girl his age disguised as a boy, quietly vies for his attention.
