About the Devil's Candy Manga Volume 4

What should have been a simple school trip to Tataratus veers off path when Kazu meets an ambitious shape-shifting tanuki, Kaiko, whose dream is to become a revered artisan. With her sights set on being an apprentice at Hitomi's grandpa' forge, Kaiko sticks close to Kazu and his friends to prove her worthiness, but she accidentally entangles them in another melee with the Scarlet Crown! This time a rematch with Pandora may not be enough. Can the Hemlock crew level up their skills and come out on top?
