: Some critics note that the anime’s animation occasionally lacks fluidity, whereas the manga’s static panels allow for more detailed and consistent artwork.
What sets this story apart from many others in its genre is how it handles the loss of innocence. There is no sudden switch from child to adult. Instead, change unfolds through small, meaningful moments—an uncomfortable truth, a difficult choice, or a newfound sense of responsibility. Ryuuki’s journey is not about becoming “wise” overnight; it is about stumbling, making mistakes, and learning through experience. This realism is what makes the story relatable and emotionally impactful.

If you'd like to narrow down this topic further, let me know:
The protagonist of this story is not a hero in the traditional shounen sense. He wields no sword, uncovers no secret jutsu, and saves no world. His battle is internal. The summer in question begins with the small, almost forgettable end of a childhood ritual: the local baseball field being paved over for a parking lot. For most adults, this is progress. For him, it is a funeral. The chapter opens with him standing in front of the chain-link fence, watching a bulldozer flatten the pitcher’s mound where he once threw wild pitches and dreamed of the Koshien stadium.
