The y/n is the most powerful dragon slayer in the world, and one day faced the leaders of each faction, including ddraig and albion.
I'm not the owner of fairy tail and DXD high school, I'm just a fan of both franchises.
Y / N along with a Dying Issei teleport to Y / N's house, then Y / N takes the Dying Issei to his house door and rings the doorbell.
Y / N: * serious * "Well my work is done, * leave Issei at the door * if you show up alive tomorrow I'll tell you what happened today."
Y/N goes home.
Issei's POV [Dream]
I see three dragons fighting they were of different colors, one was red, another was white and the last was black and blue.
Red: * serious * "Acnologia you are going to die by my hand.
White: * serious * "Acnologia you must die for challenging us both in combat."
Then I see that the black dragon killed the others like insects. Then red got up and spoke to me.
Red: * serious * "What you just saw was my death, the dragon that killed me is called Acnologia and it has the ability to transform into a human"
Then he shows me the human form of the dragon called Acnologia.
Red: * angry * "He is Acnologia responsible for my death along with Albion's."

Issei: * amazed * "That acnology you are talking about looks like Y/N."
Then I wake up from the strange dream that Y/N is an ancient dragon that killed two other dragons.
Y/N point of view
I head to the academy in my car, I just arrive and see Issei talking to his friends about his date and Issei talking to me.
Issei: * asked * "Y/N, do you remember about the advice about my date with Yuma."
Y/N: * serious * "Yes, because you ask me that, maybe they didn't serve you." * thinking * 'I think she used memory magic on those who knew Issei and it didn't affect me she must be a novice on that kind of magic.'
Issei: * serious * "Y/N, I have another thing to ask about the day of my appointment, you appeared covered in fire and lightning."
Y/N: * serious * "I think the last part was your imagination, because I was on a date with a girl."
Issei: * surprised * "You were on a date with who."
(Note: the names of Issei's parents they are Gorou Hyoudou and Miki Hyoudou.)
Y/N: * worried * "Good about who he is."
(Narrator's Point of View)
The trio was surprised by the information, then everyone went to class, the class was boring, the bell rang and Y/N went to their favorite place to sing their song.
