13xforeverThis is supposed to be another sci-fi crossover with magic. The premise is simple: a mysterious student enrolls in a magic academy, shenanigans ensued.
The writing is inoffensive, but the author had a list of all the fetishes he wanted to mention for sure. There are some fan service scenes with breasts descriptions and frequent sex scenes (mostly not detailed).
The biggest issue in my opinion is the narrative structure. The book is actually a bunch of self-contained short stories separated by a good chunk of time from each other. And the stories themselves are quite banal and straightforward in execution, so there's little to no guessing of how things will progress.
So, once again, it's a perfectly serviceable bedtime reading to pass some time, but it won't blow your socks off.
