Issei Hyoudou (The Dragon Rider of the Supernatural)

Issei Hyoudou, the current Red Dragon Emperor and being the member of the infamous Perverted Trio and world's biggest loser. He doesn't know anything about the supernatural until now after being killed by Raynare.

He believes that being a Devil is fun, meaning no human laws is keeping him from having fun and found out that he's the Red Dragon Emperor, he believes that he is the strongest being that ever existed and sees that this could help him of getting his dream of being a Harem King, but finds out that Kit and the Riders are more powerful and stronger than him since they experienced the hardships of life.

Personality:

He's a complete pervert and idiot and often get cocky whenever he thinks he defeats his opponents. Issei believes that life is hard that he couldn't suck breasts and prefers to take shortcuts in life rather than working hard and training hard, thinking that with the power of the Devil and having the powers of the Red Dragon Emperor on his side, he would be unstoppable, but seeing on how Kit and the Riders were stronger than him, he asked them if it's possible for him to try it out, but Kit told him that the Decks were DNA locked and can't be used by someone else that doesn't have the same DNA. He's also a kind person to some extent.

After being humiliated and seeing that the Riders are getting hot girls, he became jealous and angry at them and blaming their Master for not creating an Advent Deck of his own, he began to deluded himself that he's the most powerful being in all of existence
