COOKING UP A NEW ADVENTUREDennis is one of the most popular members of the Silverwing Battalion, the world's strongest party. So popular, in fact, that the party leader expels him from the group out of spite. Stripped of his home, Dennis decides to start life anew following his true calling-as a chef! His life as an adventurer might be over, but his new life as a cook is just beginning. He teams up with Atelier, a young girl who has been similarly exiled from her home, and opens up a restaurant for adventurers.
He's finally able to live out his dream, but he'll need use of more than just his cooking skills to take care of the problems of his eclectic clientele!
