Delkira's Son (half Demon-Angel)

Another peaceful day in netherworld the demon king delkira was sitting in his favorite place where he can see the netherworld that he himself create but for delkira there something still missing to him that he can't even figure out what is it.
He decide to go to market place he thought there must be something that he can buy.
He found his people happily living with their family and children delkira envy them sometimes because he doesn't have any family nor child all the women in netherworld know about him being demon king so they trying to seduce him but no one succeed because delkira want to have a child to the demoness that he will love not just because he's a demon king but because who he was.
But for delkira that's only a dream because all around the netherworld know about him.

A few years later delkira decided to go in different places (realms) to fulfil the wish that he really wants all those years

Delkira visit many realms but he didn't find a realm that have right to bear his future wife and child

He dicide to go to angle realm (heaven) but since he was a demon the angles attack him after the long time of fighting against angles.
He decide to retreat and hide he didn't kill any angle but instead he just give them a injuries .

But he was more injured than he thought delkira found a cave and hide himself there.

He fall asleep

When he woke up he saw an angle who had sky blue long hair and eyes. She's so beautiful delkira fall in love with her even though they only met

The angel notice that the demon was already awake then she became wary to him she decide to watch the demon action so she remain close to him but not that close her wariness still remain.

The demon notice the angel who was sitting not too far away from him then he notice that he was full of bandage he also saw the the food that the angel cooked. She then started to speak.

Who are you? What are you doing inside of our realm? Why you didn't kill the other angels? Where are you planning to go? How did you manage to survive to our attacks? When did you came here? So many WH question has been ask to him

Delkira blick twice and the laugh as if he can't believe what she said the girl blush because she was embarrassed but she did not only blush because of that because she also found the demon in front of him was very handsome especially when he smile

The demon stop laughing and speak

My name is Del, and I mean no harm, I only came here a few days ago.... How about you whats your name? And why your helping me? Del said

My name is Mayumi Suzuki and I'm only help you because I'm a bit worried about you and because I don't want to see someone getting hurt. She hand the food to del and start speaking again I'm sure angel food was dangerous for a demon so I have to go to the human realm just to feed you.

Ohh thank you so much I appreciate your help del said

After a few months of secret meeting of the two of them both of them started to have a feelings to each other and start dating (of course they keep it secret) they became happy

Until one day someone discovered their secret and chase after them. While being attacked by the other angels Del was trying to protect Mayumi meanwhile Mayumi was trying to open a portal to escape. Del has so many wounds and can't keep it anymore Mayumi was succeed to open the portal then Del push Mayumi inside of the portal and close the portal Mayumi shout Del's name but Del only said one thing

'Iruma'

Mayumi started to cry meanwhile Del was smiling with a warm smile without looking at her

'Thank you' that was the last word she heard before the portal was completely close.

In other side Del remove one of his ring and throw it before he died

10 months later Mayumi was give birth of a boy

The child named Iruma
He has a pure blue hair
He was look exactly like her yet also somehow resemble to his father
But the problem was not because he was halt but because he had a weak body yet very strong mana its also getting stronger every time he eat(milk)

'if i let him having such a strong mana he might explode because of mana outcontrol/explosion i don't want that'

She decide to seal the child power after the sealing she suddenly cough a blood she use too much of her magic

'I'm going to die' she know that that's why she try to find a nearby house. When she found a place she put her son to the door and kiss his forehead she left a letter with her son

{please take care of my son his name was iruma kira suzuki}

Her body was slowly vanishing she then teared a silent cry her tear turn into small silver-blue ball that looks like a gem (only one tear)

She completely vanish
