Luck & Logic

In Septpia, “Logic” is a fundamental force that shapes emotions, powers, ideals, memories, and other intangible aspects of life across many worlds. Portals infused with a world’s Logic allow alien beings known as Foreigners to cross over, endangering other realms in the process. To respond, the Another Logic Counter Agency (ALCA) recruits “Logicalists” who can bond with peace-seeking Foreigners and wield shared Logic to confront emerging threats.

Yoshichika Tsurugi once pushed his abilities too far and, for the past two years, has been unable to use Logic in battle. His return to the front lines begins when he encounters Athena, a Foreigner goddess from Tetra-Heaven, who brings him his missing Logic Card. With his power restored, Yoshichika forms a contract with Athena and joins ALCA, where cooperation with fellow Logicalists becomes essential to stopping the dangers spreading between worlds.
