Mangolia=Year 791

Natsu ran from the guild hall. He heard a powerfull roar of an dragon, familiar to the roar when his former father died. It was Agnolocia.

"NATSU! Wait for me!" a female yelled behind Natsu who turned around and saw Erza with the sleeping Happy on her hands. "Erza why are you here?!" Natsu yelled to her.

"We need to get away from here now!" She managed to say before an pitch black sword pierced trought her stomach and she fell on the ground. "ERZA!" Natsu yelled in anger after seeing who owned the sword. It was Zeref.

His eye's turned into pitch black before a fifty white points came in to his eyes and a powerful aura surounded (AN: fuck you english i cant spell but i guess you guys can get what i'm trying to say) him.

Erza looked Natsu in fear even if she was about to die. Before Natsu could do anything, Erza, Happy and he were in a room and that was the last thing they could see before they fell asleep.

In Erza's dream.

Erza looked around and saw an woman with beautiful dress on on her. "Hello Erza Scarlet." The woman sayed. "Who are you?" Erza asked. "My name is Athena godness of wisdom and war." She aswered to her.

"Why are you here?" Erza asked again. "I'm here to help you." Athena sayed before a magic circle appeared under her and a armor stand came up from it. "This is the Dragon armor it has the same abilitys that ur Dragon Slayer friends have." She sayed as the armor apeared on the stand.

It was black as midnight sky with a dragon's head looking helmet. The chest was thight and stong looking piece with on the back there came two wings made of scales from dragon's wings the legs were the most openned place from the armor. Only highsocks (hich shocks? High-shocks? idk) made of dragons tail and a tail looking sword handel cam from the place where her ass will be if she would use it.

"Me and my great aunt Aphrodite are giving you a gift with ur Earth counter part as well, mine is the armor while Aphrodite's is that ur breats will grow to MM size (Dont know if it's a real cup size) and u will be always tight as fuck but not to wide so you could handle a 10 inch long 2-3 thicks wide dick." Athena sayed while Erza looked at her in awe.

"I accept the gift's Lady Athena." She sayed

In Natsu's dream

Natsu looked around only seeing space until he heard someone speaking. "My name is Order or Chaosbecause of my two personality's of an female and male but I'm here to give you Natsu Dragneel a power called Infinity Primortal slayer magic with all of the God Slayer Magic's and Dragon and Demon Slayer magic's and all of the curse's." Chaos/Order sayed "Do you accpet this?" Chaos/Order asked. "Yes Lady Chaos." Natsu sayed before he woke up in a room with crimson heared and scarlet heared girls next to him.

Underworld in Earth

Rias Gremory was walking trought the backyard of the Gremory's family mansion until she saw a scarlet heared girl with salmon heared boy and a blue cat with white wings? She got the three of them in her magicall teleport circle and teleported them in her room to her bed as the boy just grapped her breast with the scarlet's breast as well and pulled the 2 closer as Rias just stripped herself and got next to him tightly thinking about Issei's and her break up before falling asleep.
