How about Danganronpa?
- Haikyuu
- Food Wars (i dont recommend this bc its too sexualized)
- Chihayafuru (Focuses on romance)
yumeiro no patisserie (But its base on a small group and its romance)
talentless nana although i think its more of a death game rather than a game of mind
Yeah food wars is known as literal food porn lol—
But I still enjoyed reading it for the actual story and the mc is way too interested in cooking than the girls, so it wasn’t too bad(unlike other series where the mc is just a pervert and such a turn off honestly)
I mean like, assassination classroom or classroom of the elite kinds of school based competition, i dont know where to find manga or animes which this type of feel.
