Ore no Kanojo to Osananajimi ga Shuraba Sugiru, Inou-Battle wa Nichijou-kei no Naka de Recommendations
Both anime has a male and female character with chuunibyou or used to have chuunibyou. In Oreshura, the male is embarrassed of it whereas in Inou-Battle, the male is proud of it and vice-versa for the female characters.
The romance is really similar in how the main girls has feelings for the male protagonist. Additionally, Oreshura is a harem and contains a bit of ecchi whereas Inou-Battle doesn't. Instead, Inou-Battle has supernatural aspects.
Anyways, the series both give me very similar impressions!
Both have a MC male who is Chuunibyou and has a harem (or harem situation)
"Inou- battle" however has real super powers and action in it, where as "Ore no Kanojo" foucuses more on the harem and "romance" in it.
