About

The setting is Eternal Arcadia, an otherworldly realm where magic, swords, monsters, demi-humans, gods, and ancient civilizations coexist. Future technologies such as magic trains and magitech machinery have also developed. The world is divided into various kingdoms, beastman nations, elven forests, demon territories, and divine sanctuaries. The Adventurer's Guild classifies strength from G to EX rank, and monsters are categorized similarly. Traveling through this world are Reito Hizuki, a cat-human hybrid beastman, and his older sister, Reone Hizuki. The two are the world's strongest immortal beings who freely manipulate the power of Infinity♾, possessing strength that transcends all limits. Not even the gods or the world's rulers can grasp the true extent of their power. They have no interest in world conquest or fame; instead, they wander freely, visiting unknown cities and ruins, enjoying delicious food and meeting new companions. However, their journey occasionally leads them to encounters with legendary monsters, world secrets, and incidents involving the gods themselves. With overwhelming power and free spirits, the two explore a world filled with infinite possibilities.
