High School DxD Hiro (Reborn)

This is a remake of my very first story on this app! It will feature a more consistent storyline with a basic power scale that fits the series of DxD

(The story)
The Diablos Dragon: Ryuuk, the bastard third sky dragon that Ddraig and Albion banished to the dimensional gap has been searching for a host to take in his power. The only bad thing is that many people have died because to tame Diablos, you must have a certain amount of hatred in your being, one that matches Ryuuk's hatred, if it doesn't match up with his, the 'host' dies, however Ryuuk finds solace in a host, a sixteen year old boy named Hiro who matches his hatred, and may even surpass it, only one other person has tamed Diablos, can Hiro live up to that warrior's expectations?
