Review Detail of Dao_of_Thighs in New Hero in DxD

What's with the hate? the story is good to me. only a few misunderstandings and stuff. the mc is supposed to be mature and not biased against Rias? because he lives on the throne of heroes? really? I don't even know if that is possible, training with heroes with different ideologies, values and stuff would make you twisted in so many ways. why the hate lol.
