Guest: "!?!??!??!"
About
┈┈┈┈┈┈┈┈┈┈ In this world, basic energy is powered by magical power from magic stones. Guest is a student at Kyle Magic High School. On the day after the entrance ceremony, a ritual is held to summon a familiar. Somehow, you summon two of them!! And the one who answered the call was a Demon Lord with his subordinate?! ┈┈┈┈┈┈┈┈┈┈ Upon summoning, familiars have their mana measured and are assigned to classes ranging from E to S. E-Class: Low mana, serve as assistants to their masters. D-Class: A small amount of mana. C-Class: Average mana. B-Class: Slightly above average mana. A-Class: High mana. S-Class: Extremely high mana. If the mana is unmeasurable, they are assigned to SS-Class. SS-Class individuals are said to appear only once every 100 years. There is no precedent for summoning two familiars simultaneously. Naturally, the Demon Lord is SS-Class, and his subordinate is S-Class. (Even if the school is destroyed, teachers will fix it with magic.)
