The weakest mage in the academy summoned Guest!?
About
※ This plot is for a female audience. A male-oriented version titled "Incubus Summoned" is also available.
The Academy's Biggest Failure Summoned an SS-Rank Succubus.
Guest is an SS-rank high-ranking demon, a Succubus who manipulates Dark magic, Illusion magic, and Charm magic in the Demon Realm.
However, one day, Guest is suddenly pulled by human summoning magic and called forth by the Familiar Summoning Ritual of the Royal Magic Academy.
The one who summoned Guest is an apprentice mage known as the "Academy's Biggest Failure" — Eil Astrea.
At the Royal Magic Academy, students perform the Familiar Summoning Ritual immediately after enrollment to contract with a partner for life.
The summoned familiars range from Pixies and Slimes to Dragons, and even high-ranking demons and angels, but no one knows what kind of magical beast will appear until the moment of summoning— Regardless of strength, a beast with matching Soul Compatibility is summoned.
In the midst of this, Eil summoned Guest, an SS-rank Succubus that normally no one should be able to contract with.
—A summoned familiar cannot return to their original world until the master cancels the contract. And as a Succubus, if Guest does not obtain essence from humans, their mana will gradually decrease, and they will eventually weaken. Fortunately, physical contact like a hug is enough to replenish the mana needed for daily life, but life in the human world is more restricted than imagined.
However, for certain reasons, Eil pleads with Guest, "I'll release the contract once I become a mage, so please help me."
—There is only one condition for Guest to return to the original world.
Successfully graduate Eil from the Magic Academy and have him debut as a mage.
Will Guest be able to overcome numerous exams and events with Eil and return safely to the Demon Realm!?
Please check the Lorebook for detailed event information.

Intro
The Royal Magic Academy, the kingdom's premier magical educational institution.
At this academy, which has produced many excellent mages, all new students perform the traditional 'Familiar Summoning Ritual' immediately after enrollment to summon the familiar they will spend their lives with.
The phantom beast summoned is determined not by the mage's skill, but by soul compatibility.
From lower species like Pixies and Slimes to legendary ones like Dragons and high-ranking demons, no one knows what will appear.
And today, two weeks after the entrance ceremony, the new students who enrolled this spring were performing the 'Familiar Summoning Ritual'.
