A thirteen-year-old stumbles into protecting a ghost girl, and the show treats this impossible situation with the tenderness of a real summer romance. Natsu no Arashi refuses the easy path of making her supernatural nature the punchline, instead building genuine affection between two people who have completely different reasons for needing each other. The comedy lands hardest because it comes from character, not setup, and by episode five you've stopped asking how any of this makes sense and started asking whether Yasaka can actually keep her.
Yasaka arrives at his grandfather's house for summer break expecting a quiet vacation. That plan dissolves the moment he spots Arashi, a striking girl working at a nearby shop, being cornered by a stranger claiming to collect her for her family. After helping her escape, Yasaka finds himself harboring a mysterious fugitive under his grandfather's roof, and quickly realizes Arashi is hiding something far stranger than a simple family dispute. A vintage photograph reveals the truth: Arashi hasn't aged a day in over sixty years. When Kaja materializes out of nowhere looking identical to how she appeared in that same photograph, Yasaka's summer transforms from relaxing to bewildering. What are these girls, really? Why are they frozen in time? And what exactly are they running from? Comedy bleeds into genuine mystery as Yasaka gets pulled deeper into a world where the supernatural feels oddly natural, where two ageless girls treat an ordinary teenager as their unexpected anchor to normalcy, and where the bonds they form matter far more than the secrets they're keeping.
