The Oni girl is more deredere. If you mean the tengu, then it probably the one that's outright violent to the object of her affection. Or else the tengu doesn't care about the MC at all and it all has to do with the oni girl.
Wow, @JasmineTea !
Where did you find this manga?!
I'm loving this vibe; mMC is just a mensch, doing what he can in life, communicating better than the average 18-y.o. boy... and fMC is the SAME!
It is Best; thank you.
