Reincarnated as the Piggy Duke: This Time I'm Gonna Tell Her How I Feel! Volume 3

Kirsch is in an uproar. Who should come to visit but the upcoming queen of Daryth, Carina Little Daryth herself? Due to Slowe’s recent accomplishments, he ends up accepting the job to take care of her while she is here at school. He follows the free-spirited princess everywhere; during classes, during breaks, and— “Slowe, won’t you go explore the dungeon with me?” Princess Carina reveals the real reason why she is here at Kirsch: to look for a dragon hatchling, which would bring extraordinary military power to Daryth. Slowe heads off with Princess Carina on an expedition into the dungeon. But in his absence, the unexpected happens and the whole school is thrown into chaos. “Charlotte, I swore that I would never, ever lose you again.” Will Slowe make it back in time to rescue Charlotte and the school from the crisis they’re facing?!
