Review Detail of Seraphy64 in Mob devil's guide to surviving DxD

fic is about average for webnovel. non native English speaking writer, but the author doesn't do terribly. the best thing about the story is some aspects of the MC. he min/maxes the shit out of his new opportunity. the spells he creates initially to give him an edge are the perfect choices, thought acceleration, parallel thought processing, and memory repository. then he Rock Lee's the shit out of his life and becomes OP (for his age). only thing missing really is mastering structural analysis from fate.
