One day, the wind-manipulating Alchemist Lyle is suddenly notified by the party that he is out of the force. Alchemists, who are neither the vanguard nor the rearguard, were once regarded as important positions in the party, but due to the changing times, their evaluation as a halfway class has become decisive. There was no recruitment for the guild, and when he was about to decide to close the business, the one who appeared in front of Lyle was Teresa, a magician of fire. She asked Lyle to be her escort, and a new duo was born here.
