Kadokawa‘s Dengeki Bunko imprint launched the Sabikui Bisco novel series with illustrations by K Akagishi and world-building art by mocha in 2018, and published the eighth volume on January 8. The light novel series was the first to top both the overall ranking and the new work ranking in the same year of the Kono Light Novel ga Sugoi book. Yen Press is releasing the novels in English.
The story is set in Japan after a “Rusting Wind” has corroded everything. People live in fear of the rust that corrodes cities and life in general. A boy named Bisco Akaboshi from the despised Mushroom Guardian tribe embarks on a journey to obtain the “Rust-Eating” mushroom — a miracle drug that purifies all rust — to save his dying teacher.
During his journey, Bisco encounters Miro Nekoyanagi, a good-looking young doctor at Imihama, and together they search for a countermeasure against the rust consuming Miro’s beloved big sister.
The light novels inspired a 12-episode television anime that premiered in January.
