Tanya, a mage who was exiled from her adventurer party for the unreasonable reason of "because she is a woman", accidentally breaks the seal of the great witch Laplace, and decides to form a new party together. After having her job changed from being a mage to being a magic swordsman, Tanya powers up and joins the guild ranking battles with Laplace to get back at the party that had banished her. It may be sudden, but the strongest tag team proves to be a great success! (Source: Sunday Webry, translated)
