Review Detail of FhailBhais in Highschool DxD: A new opportunity

Easily one of, if not the best DxD fanfics I've come across. The author plays with the canon and brings characters from other fandoms into the story in ways that actually make sense by adapting their powers and such to fit the existing power system of this world, and changing their race (species) to fit as well, but in a way that doesn't betray the core of the existing character. The MC is very well written, and isn't just OP for the sake of being OP. He struggles, he has to work and earn his powerups and even has drawbacks and penalties for overusing his abilities. Looking forward to reading more.
