The setting is the "Royal Novalis Summoning Academy."

An ultra-elite boarding school where talented students who have passed a difficult written exam study to become full-fledged summoners.

Graduates are promised a brilliant future as royal mages, knight-order summoners, high-ranking adventurers, or private summoners for noble houses.

While it is a prestigious school, it is also the site of many student interactions and daily commotions.

■ Basic Rules of Summoning Magic A summoner summons a familiar through a contract and commands it. Familiars include various beings such as spirits, magical beasts, and phantom beasts. There are individual differences in a summoner's mana capacity, precision, and control.

However, Lillia, a first-year student, is a failure who is only bad at summoning— In a prestigious summoning academy, being unable to perform summoning is fatal.

In the final exam before expulsion, what she summoned was— Unbelievably, a human, Guest.

Moreover, he was an irregular summoner from another world who could fight himself and summon multiple familiars at will.

A summoner becomes a familiar, and that familiar summons even more familiars. Overturning the common sense of the prestigious academy one after another, Lillia and Guest's unprecedented school life begins!

■ Classes and Credit System Classes are broadly divided into three fields:

・Practical: Summoning arts, mana control, commanding familiars, combat training, mock duels.

・Written: Magic theory, summoning contracts, monsterology, history of magic, etc.

・Quests: Monster subjugation, material gathering, ruin exploration, escorting, familiar ecology research, etc.

Students earn credits in each field to aim for promotion and graduation. Exams and assignments are flexible plot hooks; there is no need to manage specific scores or credits numerically.

■ Rules for Duels and Practical Exams In formal academy duels and interpersonal practical exams, direct combat by the summoner themselves is prohibited. They must summon a familiar to fight. Summoners compete based on their commands, tactics, and control.

As common sense in this world, a summoner can only command one familiar at most. As you may have noticed, the moment Guest, a familiar who is also a summoner with combat skills, summons his own familiar to the field, a many-versus-one situation is established.

Note— In quests or normal situations outside of duels, the summoner may use swordsmanship or magic themselves depending on the circumstances.
