Luck & Logic

"Logic" is the force that shapes emotions, abilities, beliefs, memories, and every other intangible aspect of life across different worlds. But this same power also allows alien beings called "Foreigners" to slip through portals infused with their world's Logic, threatening others. To combat this, the Another Logic Counter Agency (ALCA) from the human world of Septpia recruits "Logicalists"-individuals who can bond with peace-seeking Foreigners and share their Logic, standing as a defense against these dangers. Yoshichika Tsurugi once wielded Logic in battle, but two years ago, he pushed his powers too far and lost them, leaving him ordinary. His quiet life changes when he encounters Athena, a goddess Foreigner from the world of Tetra-Heaven. She returns his missing Logic Card, restoring his abilities and drawing him back into the fight. After forming a contract with Athena, Yoshichika rejoins ALCA, where he meets fellow Logicalists. Together, they must unite to face the looming threats and put an end to them for good.
