Erytheia Ashmedai/Tropes

A-G
Alternate Universe Counterpart: It's quite possible that Erytheia is the alternate universe counterpart to Lilith from Fairy Tail: Vice. Given both of the series are having crossovers, and Fairy Tail (and Dawn itself) has established and abused the existence of alternate timelines, the Sun Trilogy and Vice may exist on opposite ends of one timestream. Wibbly Wobbly, everybody.
