Games Like Guardian Beast

A commercially published Japanese SF-fantasy novel, rebuilt as an interactive bilingual reading experience

Guardian Beast is a reading-first interactive edition of the Japanese SF-fantasy novel commercially published in 2015. In 2026, author Takahiro Yonemura extensively revised and reconstructed his original work with full-story illustrations, manga-style scene direction, sound, animation, and meaningful choices.

From a bookstore novel to an interactive digital book

The story began as the Japanese book Guardian Beast, commercially published and distributed in 2015—years before today's generative-AI boom. The physical edition reached bookstore shelves and was promoted at author signing events. For the Steam edition, Yonemura substantially revised the published manuscript. The novel's flow remains central, while light branching, music, video, and scene direction deepen the reading experience. This is interactive reading software built for enjoying a story, rather than a large-scale adventure game.

What this Steam edition includes

A boy, a dragon, and the bond between people and their Guardian Beasts. As war and an approaching catastrophe close in, the story moves from quiet encounters to fierce battles, heavy loss, and a final spark of humor.
