Plot
Characters
- Alto Goldfield (アルト・ゴールドフィルド)
- First year at the Ortigia Academy of Magic, he is an A-grade student except in summoning class. At risk of repeating a year unless he performs a successful summoning, he discovers a grimoire in the school library. Performing the spell within, he succeeds in summoning a naked demon girl named Vermeil. His blood possesses a high degree of mana, making most summoned spirits avoid him despite his calls. Vermeil on the other hand likes "potent" mana, hence why she answered. Despite her high degree of power, she agrees to become Alto's familiar. His childhood friend, Lilia, is head over heels in love with him, but he never loved her in the slightest, and is often annoyed and even creeped out by her, making him avoid her at all costs.
