The possibility of worldbuilding and new species amongst her classmates, friends, and teachers could even happen. As of right now, only Ruri is the only mixed species character. If she is the only one that is fine too, but the worldbuilding possibilities are an interesting point the mangaka could build upon.
The characters are sweet, Ruri's mother seems supportive and her friends are very sweet and understanding, though because there are only 4 chapters currently, not much else can be said about them.
I think this could make for a very sweet slice of life manga that could have a lackadaisical viewing of the charming yet lazy Ruri's journey of self discovery and surviving high school.
