MTL-The red dragon just wants to do whatever he wants

Synopsis

If the leader of the red dragon can release half of the lava, the world will welcome the most intelligent king - " The Book of the Red Dragon. " David turned the page of the book, incinerated it to ashes with a puff of dragon's breath, and prepared himself a bottle of Balrog's mixture. To hell with that ridiculous sanity. I just want to do as I please! This tale follows a red dragon who journeys through an alternate realm, gaining infinite rewards as long as he practices the seven deadly sins.
