It's time for some fun in the sun! Our heroes head to Auguste's Vanera Beach for the grand opening of Sierokarte's new shop, and take a well-deserved vacation at the local resort. They reunite with Jin, a wandering swordsman they had met on Sable Island.

Jin saved a fisherman named Kaz who had collapsed in the street, and for Kaz's sake, took up the challenge of searching for the secrets needed to reel in the mighty Bonito. Eugen and Soriz, impressed by Jin's resolve, join the fray. The crew also decides to lend a hand, even though they're busy helping out at Sierokarte's seaside house. Everyone's heating up! Get ready for a blazing summer!
