Fairy Tail Gaiden - Raigo Issen

After Fairy Tail disbands, Laxus Dreyar and the Thunder God Tribe arrive at Blue Pegasus, hoping to join the guild. They are welcomed, but soon discover that Blue Pegasus is not quite like Fairy Tail: alongside its guild activities, it also operates as a host club. Before Laxus and his companions can settle in, Ichiya is kidnapped by the rival organization Red Princess. The group sets out to rescue him from the unusual organization.
