Freshly recovered from the hellflame grizzly attack, Sarasa, along with new team members Iris and Kate, gets to work reopening her shop just in time for summer. She develops a cooling hat as a product to sell to the villagers...but it’s a bit too pricey for the town’s barter economy! Just as she’s about to crack the economic code and generate her most popular product yet, another alchemist shows up, one who gets in the way of her buying one of the hat’s main ingredients, icefang bat fangs. She who controls the ice controls the summer! The battle for commerce in South Strag is on!
