Pens Down, Swords Up: Throw Your Studies to the Wind Volume 3

Across the kingdom, all eyes are on Allen Rovene, Class 1-A’s mysterious new troublemaker. However, Allen’s only got one thing on his mind: vacation! Between overcoming Godolphen’s challenge and joining the Royal Order, he hasn’t had it easy since school started—but summer’s here at the Royal Academy, which means it’s time to close the books and open the door to adventure. From exploring his new world to hanging out with his friends, Allen’s determined to enjoy every last second his break has to offer—and with his newly invented magic up his sleeve, he’s going to go wherever the wind takes him! Perhaps he’ll run into a familiar face along the way...? But before he can set off on his trip, Allen’s going to have to confront the battle he’s been putting off for far too long: a reunion with his terrifying sister, Rosa. And for some reason, his classmates have decided to come along for the show! Will Allen even survive long enough to experience the free-spirited summer of his dreams?
