HimaNatsu: Of Churches, Sunflowers, and Long Summers

After eight years away, Yosuke Ashitaba returns to the place where he spent perhaps the most important days of his life: to the small building nestled among vibrant amber flowers—Oboshiro Church.

"Yoh?!"
"Is it really you, Yoh?"
"Yeah. I'm home."

There, he reunites with a handful of childhood friends:
Yomi, the girl who welcomes him as though he'd never left.
Daiya, the young lady who comes from afar just to see him.
Ruka, the one who's spent eight years awaiting his return.
And Hina, a fresh face living in the church.

Faced with the demolition of this church they all once called home, the five of them work to make this final summer together one they'll never forget. And so, set against the backdrop of a church by the sea, so begins the tale of one last cheerful, nostalgic, yet bittersweet summer.
