Such a manga would likely be considered inappropriate and creepy. It's not a common or positive theme in manga.
This kind of manga could potentially be in the thriller or horror genre, but it's not a typical or widely accepted storyline. It might raise ethical and moral concerns.
I can't think of many mainstream manga with this theme. Usually, manga focuses on more positive, inspiring, or adventurous storylines rather than something like a guy stalking a girl.
I don't know of one off the top of my head. Maybe check out some popular manga series that deal with darker themes and see if any fit the description you're looking for.
Common themes in stalking girl manga could include the psychological impact on the girl, the stalker's motivations, and the social reactions to the stalking. These themes explore the darker side of human behavior and relationships.
It could potentially refer to a manga involving themes of someone following a girl in a disturbing or inappropriate way within the context of hentai.
Maybe it's a mystery manga where the guy follows the girl to solve a puzzle or uncover a secret related to her.
It could be a manga that focuses on the guy's moral struggle or internal conflict about not harming the girl. Maybe there's some external pressure or temptation pushing him to do it, but he resists.
There are different possibilities. It could be a fantasy manga where their love story is intertwined with magical elements. Or perhaps a school-life manga centered around their daily interactions at school.
It could be a romantic comedy manga where their childishness leads to funny and heartwarming moments.
It could also be a fantasy manga where the height difference plays a role in some magical adventure or quest. The contrast in height could add an interesting dynamic to the story.
Such a manga could involve a magical or sci-fi transformation. Maybe it's a story of self-discovery and identity exploration for the character.
It could be a fantasy manga where the character has some magical or supernatural ability that makes them half of each gender.
