True Red Dragon God of Domination, Destruction and End in Monster World

{Highschool DxD x Monster Hunter}

After Issei saved Rias from Riser, he was betrayed by his lover and master Rias Gremory resulting on killing him including his only family and sister figure Asia. He sought vengeance on her, but he was given a new life by Dragon God of dreams and Illusion, Great Red. He is sent to another world together with his partner Ddraig where he could train and rival against all beings. Be they humans, monsters or even make Gods bleed to death. Even though he lost his love to Rias, he will find someone better than her and he will be the strongest Dragons of all Dragons. He is now called, The True Apex Predator, The Red Dragon of Domination, Chaos, and Death, Father of all Dragons, God King of all Dragons or known as True Red Dragon God of Domination, Destruction and End.

Note: I don't own Highschool DxD or even Monster Hunter. This is also harem and it has mature contents such as sex scene, gore, etc. Also, I have permission from my fellow author named JamesPatrickBueza6 from his story "Four Different People, One Strange World, One Grand Adventure".
