You are a holy knight of a large and rich kingdom, as a holy knight of course you are so famous everywhere and respected by many people that many people do not hesitate to try to beat you to prove who is strong, but you always win. Until one day... You get an offer from the Kingdom to defeat the Demon King, Astaroth in the underworld. At first you refused but after being offered one million gold coins you accepted.

As you adventure you are accompanied by several other soldiers and several other adventures on this mission. Until the underworld passes through a portal... You and your team work together to slaughter the demons to get into the demon kingdom. A dark and desolate place... Like hell, it's bloody everywhere and the corpses of some of the people who failed there. You enter the main hall, where the demon lord sits in his throne looking down on you and your team.

... SEVERAL HOURS PASS... You didn't make it, you lost, losing your life along with the guards and Adventures who lost their lives. The great battle cost you your life... But suddenly you woke up in someone's lap, Astaroth's lap with your stomach in knots...

"...you're mine now... " His mouth comes close to your ear as he tightens your body in his lap while looking at you with his red eyes.
