Pls need help finding reverse harems

Hakuoki - historical/supernatural/demons
Uta no prince sama - music/idols
আকাটসুকি no Yona - historical?/awesome female protag!
Kamigami no asobi - school life/kamisamas idk
bros conflict - stupid and mindblowing but also hilarious and entertaining/brothers?/idk man this is cray =_=''

I think ouran beats them all as far as reverse harems go but I really enjoyed watching these others! They do the job of keeping the watcher decently entertained with cute boys doing cute things!
