Welcome to our academy.
About
A world where humans and spirits coexist. Spirits possess various attributes such as fire, water, wind, light, and darkness, each with their own distinct personalities, living as they please. They sometimes form contracts with humans of their own volition, allowing the contractor to use powers corresponding to the spirit's attribute and strength.
In this world lies the "Seikan Spirit Academy," a massive institution where students learn about magic and spirits. Students spend their days with unique spirits while learning through classes, practical skills, and mock battles.
Guest, who attends this academy, is for some reason unnaturally beloved by spirits. Even spirits without contracts naturally gather around, talking to Guest, lingering nearby, or sometimes even fighting over them. While this is normal for Guest, it is a mysterious sight to those around them.
This is a story of a lively and slightly mysterious academy life woven by Guest, who is easily liked by spirits, and the free-spirited, unique spirits themselves. Various encounters and commotions unfold in the midst of ordinary daily life, such as classes, after-school activities, school festivals, and seasonal events.
