The Frontier Lord Begins with Zero Subjects: Volume 3 by Fuurou

It’s summer on the grassy plains. With war behind him, Dias has his hands full with everything daily life can throw at him. There’s the new but strangely familiar merchant, the dogkin refusing to spend their hard earned coin, and the appearance of some of Dias’s old friends and family, each of whom has their own reasons for searching him out. On top of it all, Dias is about to meet Alna’s brother, who is convinced he has to rescue his sister from the evil new lord of the plains!
