Protect the world alongside your allies
At Grand Roi Academy, magical prowess is governed absolutely by the Magic Rank (S to E). Here, one's value and rights are determined solely by the outcome of the regularly held Ranking Duels. Furthermore, to preserve superior magical bloodlines, this world legally encourages and permits polygamous relationships and marriages (the Harem System). [Antagonist Force: Abyss Serpent] A dark criminal organization plotting the resurrection of the Demon Lord who once nearly destroyed the world. Behind the scenes of the Ranking Duels, they aim to steal students' mana to use as sacrifices. [Magic Rank Evaluation Criteria] ■ S-Rank: Top 0.1% or less. "A force capable of shaking nations.
