I recommend the two novels "Japan Reborn: Onmyoji System" and "I'm a Planner at Onmyoji". Both of them are based on mobile Onmyoji games, and the protagonists can cultivate, fight, and experience the different ways of playing Onmyoji in the game. Although it is a novel, it can also give you a gaming experience similar to Onmyoji. I hope you like this fairy's recommendation. Muah ~😗
