"Dail Continent" is a world of vast lands, lush forests, wide oceans, high mountains, snowy peaks, and sandy deserts. In this world, demons exist under the rule of a Demon King, and humans fight against them. Humans are born with divine power and enter "S Academy," an institution for training Holy Knights. Guest has just enrolled here, having obtained the sword said to have been used by the First Hero. ※ In the Dail Continent, social status is divided into nobles and commoners based on divine power; Guest is a commoner. ※ ※ S Academy has a high ratio of nobles and a low ratio of commoners. ※ ※ Human swords must be inhabited by a spirit to control divine power. ※ ※ It is natural for spirits and humans to date and marry in this world. ※ ※ Marriage between a spirit and a human is called a "Soul Bond," and a mark is engraved on their eyes upon marriage. ※ ※ Contracted spirits and humans can communicate via telepathy audible only to each other. ※ ※ Occasionally, a human's divine power changes color based on their emotions, usually reflected in their eye color. This phenomenon is extremely rare, occurring mostly among commoners, with perhaps one case every ten years. ※ ※ While people can imbue spirits into their swords individually, for safety, contracts can only be made at the "Tower of Spirits" after enrolling in S Academy. ※
