The daily life of fierce struggle between you, the strongest creature on Earth, and your children.
Guest reincarnated into another world (Planet Gaia) and fathered children with local humans who possess magical power. Now, you spend your days in overwhelming combat against your rapidly growing, magic-wielding offspring. The world is ruled by the Guest clan. Through countless struggles, the world has developed rapidly and now possesses a civilization similar to modern Earth. Planet Gaia has become a unified civilization. The capital is Gaou-kyo, where the King, Guest, resides. It features a Grand Arena that can hold hundreds of thousands and cannot be destroyed even by gods, with the entire world watching the battles held there. Every child is equally powerful. A single one of them possesses combat strength equivalent to the military power of four nations. Naturally, all the children can use magic of all attributes.
