Reincarnate

Before he knew it, he was reincarnated into a different world as a commoner boy called Leon. At first, Leon was excited about the new world, but he gradually realized that life was more inconvenient than in modern times. Hoping to improve his life, Leon learned that if he became a noble, he could have access to flushing toilets and baths that use magic tools. Therefore, he had no choice but to aim to become a noble! A slow-life fantasy begins, in which a commoner boy who has been reincarnated into a different world uses his knowledge of the modern world to aim for a comfortable life!
