Kuranosuke has reached his 30th birthday, becoming a ‘wizard’ (sadly) and ‘celebrating’ with his 2D waifu Kanata. Then a bishoujo who called herself ‘maou’ came out of his monitor! It appeared that he could become the legendary ‘most powerful wizard’ who is greatly sought after by the four maou who wished to unite the demon world. In order to become the ‘most powerful wizard’, he needed to train his vitality by having lots of sex.
