Nameless Roundabout

After a lifetime of suffering, Taira Mokawa came to a different world after his death. He was surprised to find that the people around this world were slow to absorb magic power and didn't even know that the magic power needed to be absorbed! As a person who traveled to another world, Taira Mokawa achieved what others achieved decades earlier at the age of twelve! A pair of diligent hands creates a gorgeous magical world, and a firm and cold heart squeezes into the master's position. As a human being, he resisted the demons with a lifespan of hundreds of years, and left behind a story that will last forever. (Sword and Sorcery, Madonna, single heroine, no system,)
