Zero Sum Original Anthologies: Arcana

Long-running themed anthology series published by Ichijinsha for its Zero-Sum and Zero-Sum Ward magazines. Each volume gathers original one-shots by a rotating roster of regular contributors built around a shared concept, with featured themes including butlers, thieves and rebels, princes and princesses, vampires, samurai and Japanese-style settings, special forces and teams, magic users, a second butlers installment, transformation and personification, conflict and secret societies, time travel, demons, romance and reverse harems, ninjas, school uniforms, and fairy tales. Cover and frontispiece art rotates between artists such as Minekura Kazuya, Kouga Yun, Takayama Shinobu, Kinoshita Sakura, Mikanagi Touya and Haibara Yaku, with recurring crossover entries like Magami Guriko's Kinoko to Kappa appearing across multiple volumes. The series functions as a showcase for the magazines' authors working outside of their main serializations.
