Proven appeal of subject: Over 30,000 copies of the original novel series have been sold in print and even larger numbers in digital. Japanese turnout is strong, with THREE manga adaptations being released simultaneously and the third anime series airing in Spring 2022. Artwork: Multiple full-page illustrations (Including a double-sided full-color two-page spread and approx. 10 black-and-white per volume) add extra value and provide crossover appeal with the manga buying audience.
