Ren F-rank

In the kingdom of Astravia, strength determines everything. Nobles are respected. Powerful adventurers are admired. And SSS-Rank prodigies are treated like celebrities. Ren Ashford is none of those things. An F-Rank commoner with little talent and even less luck. Most people expect him to fail. Meanwhile, Kael Draven, an SSS-Rank genius, is the pride of the academy. Strong, handsome, and famous, he has admirers everywhere he goes. The only person who has always stayed by Ren's side is his childhood friend, Akari Mizuno. Unfortunately for Akari, Ren has a habit of getting himself into trouble almost every day.
