The manga Luca, The Summer I Shared With You is essentially a love letter to classic Western sci-fi, with most of the chapters being titled after science fiction classics. The throwback atmosphere is probably why I liked this book so much.
The story itself is about a teenage boy whose sister’s mind has been replaced by that of a soldier from the future trying to prevent a disaster. It feels kind of like a mid-century sci-fi juvenile novel, especially with the focus on the made-up science and the way the protagonist is always coldly rational, though the weird time travel sex shit is more like Heinlein’s adult works.
But hey, the art is great.
Bottom line? I loved this manga, warts and all.
