Their Backstory:

Both parents were once part of the supernatural world devolos a devil fighting for his kind and angelica an angel fighting for her angel kind.

By the sight of the great war made them realize there is no chance of peace when both red and white dragons decided their own fight.

Both of them work together once to stop them while falling in love in the middle of a fight and once the two dragons have stopped they disappeared without anyone noticing who thought they were dead except a certain fallen angel General.

Many years together in disguise as humans and married to have a happy life and their great joy of the birth of two twin sons issei the first born and (y/n) the second born.

During their lives together as a family for sometime until an unfortunate incident happen made both boys unlocked their sacred gears which both devolos and angelica never thought it was possible.
