MC seems to be a Mary Sue...
Author is lowkey tryna make mc perfect lmao, her only "flaw" is the "hardships" given to her by Ruri.
She's a mixed pretty girl with lapiz lazuli eyes and also pretty intelligent so she got into a prestigious university. Now she's in another world and is somehow, for god knows what reason, is beloved by all dem fairies and is powerful enough to affect the whole kingdom. Oh yeah, and she's also on her path to becoming (like she obviously already is tho with all those fairies supporting her lols) to becoming the most powerful magician.
Ohhh that's what you meant!!!! I apologise for assuming. She does come off as really OP. But that ties into the whole cliche of the shoujo genre. As, even her introduction to the story was comical, even though what happened would normally be treated as a serious situation. Because of this, I wouldn't expect much to change, but..eh.. if she doesn't run into situations where she's underpowered, then her main fault could be the fact that she's too overpowered, which may in itself draw in the story's troubles & dealing with it could be the MC's internal development.
Aww, I want to read more about the blondie
