The world’s strongest Sage was bored of being the strongest. Being able to defeat the strongest of dragons, and the toughest of demons with ease, he decided to shut himself and create a new type of magic, Reincarnation magic, hoping that he will have another chance in life, but this time, to live a quiet peaceful life. However, the spell didn’t work as he intended, and he was reincarnated into another world. A world with no magic while technology and science advances the world, and onmyouji protects the world from ayakashi, monsters that come from the realm of hell to cause destruction upon this world. Retaining his memories (Barely) and ability to use magic, the reincarnated sage will do his all to live his desired quiet peaceful life in another world.
