Magika no Kenshi to Shoukan Maou Novel

Fifteen years ago, humanity discovered magic and mythical beings from another dimension. Seven nations formed alliances with these beings, gaining their loyalty. On their fourteenth birthday, individuals are chosen by mythical beings and marked with a stigma, becoming summoners. Consequently, schools were established to train summoners and their bodyguards, magical swordsmen. In the present, Kazuki Hayashizaki is unexpectedly chosen as a summoner, a rare occurrence for males due to their limited mana. As the first male summoner, Kazuki faces intense scrutiny. His sister, a magical swordsman, opposes his enrollment in summoner school, as summoners often view magical swordsmen as inferior. Despite this familial conflict and his low E-rank status among peers who also belittle him, Kazuki is resolute. He is determined to excel at summoner school and prove his strength.
