The Young Lady and Her Lackeys Are Going to Pick on the Transfer Student - Oneshot

[flannan]

A perfect blonde student. I bet somehow SHE won't be burdened with some melancholy and traumatizing secret by the mangaka. I just have a hunch about that. Maybe something to do with mangaka being obsessed with portraying blonde characters as inhuman unemotional supergirls.

So, I've been rereading oneshots by the author, and I do not see any pattern like this.
The only blonde that fits your description is from Tomo-chan, and she isn't emotionless either - just non-transparent. She is clearly feeling emotions, they just don't show on her face.

This has to be those manga where I really don't understand anything that happened.
But I like it that way! 😂
