Luck & Logic

In the year L.C. 922, the world was plunged into sudden chaos. Tetra Heaven, a legendary land, had just ended a century-long war. The defeated gods sought refuge elsewhere and invaded Septpia-the human world-launching brutal attacks. To defend cities from these foreign invaders (angels),ALCA, a special police agency, deployed its Logicalists, agents forced into action whether they wanted to fight or not. Through their abilities, Logicalists could enter a trance with goddesses from the other world, giving them a fighting chance on the battlefield. Yoshichika Tsurugi, an ordinary civilian without "Logic," lived peacefully with his family until an attack forced him into shelter alongside others. There, he encountered Athena, a beautiful goddess who possessed the very "Logic" he lacked. Now, bound by fate, Yoshichika and Athena set off toward an uncertain future.
