Sadaharu Imao is a twenty-eight year old ero-game artist and writer who's the reincarnation of Sex Demon King Shadahl.
The origin's of Sadaharu are tied to another dimension in a fantasy realm. He was once the Evil Sex Demon King Shadahl (淫魔王シャダール, In-maō Shadāru), who was abducting all the beautiful women of the lands, with the aid of his bird-familiar, Sara; and raping them into submission with his sexual magics. Just as his plans for world domination were nearing fruition. The three warrior-heroines, Maria, Eclair, and Miina, discovered his hide out. Though he nearly broke their will with the power of his semen, their combined efforts defeated and nearly killed him. He was saved by Sara who sent his soul away to be reincarnated.
Shadahl was reborn into the soul of a human named Sadaharu Imao. He actually grew up with no memories of his past or magical powers and had an unnatural phobia of women. He cringed to even touch them despite his own feelings. After discovering ero-games, he was able to life out his lust in his fantasies. He was driven to become an ero-game designer but none of the stories he wrote on his laptop ever made it big. He eventually began to create a game that he was unknowingly basing on his previous life as Shadahl.
