Digimon x Fairytail

BlackWarGreymon is given a Second Chance at life as a real Digimon by Azulongmon, but in another world called Earthland with a human Partner, a Boy named Seich, who has been unfortunate enough to be born with Black Hazard Magic, a highly dangerous magic that allows the mimicry of other magic in a more dangerous and powerful fashion, because of this he is an outcast to most, and a monster to others. BlackWarGreymon takes the offer, feeling a kinship with the boy. He's reduced to a Botamon, and sent to Earthland.

The digivice Seich and BlackWarGreymon will have is Called the D-Dial, its a pocket watch like Digivice with a twist gimmick like Ridewatches from Kamen rider Zi-O, you twist it to left once for Champion, Twice for Ultimate, and Trice for Mega. Plus a plug spot on the bottom to allow a DNA digivolution with another Dialvice, by linking and turning four times.
