Long ago in a place unknown to man a feud between heaven and hell was taking place. There was sorrow, despair and anger every where you went, though at the same time god/kamisama was creating a world completely different from heaven or hell the only one who knew of this was the fallen angel Elyoris, he was born in heaven yet to his dismay he was disowned because of his indifference, as soon as he appeared out of his cloud flower his wings appeared although it wasn't white like the other angels in heaven so was casted out.
Years passed
Elyoris became very powerful and also grew to his mature form.
One day he met an angel in a place called limbo the hidden place between heaven and hell, there by the beautiful oak tree by a lake sat an angel more beautiful than anything he had ever seen. He walked torwards the beauty pretending not to notice her presence and there he sat beneath the tree's shade, as he had expected the angels eyes fluttered open at the sound which Elyoris made as he sat down on the soft luscious green grass. It wasn't long before the angel decided to talk to the stranger who had disturb her peace
"who may you be" asked the curios angel
"my name is Elyoris, I am sorry did I disturb you" he replied
"my name is Alexiel, and yes you awoke me from my sleep" she replied in a moderate tone
it wasn't long before they started having a decent conversation, dyas passed they met each other in limbo almost every day, each time they met they didn't notice that their love for each other grew, but since this emotion was new to the they wondered what it was until one day their question was answered by god but that wasn't the only thing that they learned they learned that with their powers they could make an offspring of their own, so they created one by pouring almost all of their power and combining it, due to the strong energy release the elders of both heaven and hell were able to sense them knowing this they created a portal to bring their child to the new world's future where in the being called man was alive, they prayed to god for the child's safety and just before she put the cjild into the portal she whispered "be safe my dear Alexies"
Beyond the portal in the new world called earth
a 22 year old man was walking down the streets of Tokyo when all of a sudden he saw a flash of blue light then right there before him appeared a child with violet hair and deepset black eyes as well as black wings which eventually receded into her back. The man took pity on the little child he saw so he decided to raise her himself, and also because he wanted a daughter which his late wife wasn't able to give birth to due to an accident.
