I was living a life of a NEET, and I was supposed to have died suddenly because of my daily indolence - but when I woke up, I had become a baby. It seems that I was reincarnated in another world where magic exists. I was born the son of a lord in a remote village, and began to lead a second life with my beautiful mother Kara, my big-breasted maid and nanny Ruina, and my beautiful sister Amelia, who is not related to me by blood. As a teenager, I've grown up and enjoy my daily life in a different world using my top-level magical ability and modern knowledge...?
