Ok so I would recommend for;
Comedy/Magic/Romance: Familiar of Zero (beware this anime has 4 seasons)
Romance/Comedy: The Pet Girl of Sakurasu (pardon my spelling)
Action/ Comedy: Assassination Classroom
Demons: Higurashi, Another, Corpse Party (very scary)
Adventure: akame ga kill
And must see animes: dragon ronpa, a certain scientific railgun, and a certain magical index.
