Kinsō no Vermeil: Gakeppuchi Majutsushi wa Saikyō no Yakusai to Mahō Sekai wo Tsukisusumu #11

Kinsō no Vermeil, known in English as Vermeil in Gold, is a fantasy manga series written by Kōta Amana and illustrated by Yōko Umezu. The series began serialization in Square Enix's Monthly Shōnen Gangan magazine in 2018. The narrative follows Alto Goldfield, a student at a magic academy who inadvertently summons a powerful, legendary demon named Vermeil to serve as his familiar, setting the stage for an adventure centered on magical progression and interpersonal dynamics.

The eleventh volume continues the progression of the series, maintaining the distinctive character designs established by Umezu, who blends traditional fantasy aesthetics with a modern shōnen art style. The series is noted for its focus on the collaborative bond between Alto and Vermeil, which serves as the thematic anchor for the story. Like its predecessors, volume eleven was produced during the ongoing tenure of the creative team as they work to expand the series' intricate world-building and magical lore for a dedicated readership.
