Luck & Logic

In the year L.C. 922, a sudden crisis emerged as the defeated gods from Tetra Heaven, a legendary land where a century-long war had ended, sought refuge in Septpia, the human world, and launched an attack. ALCA, a specialized police agency tasked with defending cities from angelic invaders, relied on Logicalists who could enter trances with foreign goddesses to gain a combat advantage. Yoshichika Tsurugi, a civilian without the "Logic" ability, lived a peaceful life with his family until an attack disrupted their safety. Forced into a shelter with others, he encountered Athena, a goddess who possessed the "Logic" he lacked. Together, Yoshichika and Athena embark on a path toward an uncertain future.
