I don't remember much of my childhood.  My mother died while giving birth to me.  I was raised by my father until he fell in love with the human woman Eva.  Now before I go any further some background.

My name is Izuku, I am the oldest son to the dark Knight Sparda who is a devil.  Like I said earlier my mother died giving birth to me, she was from a race called dark nephilim, or devil human hybrids.  That being said I am 3/4 devil.  Ever since I can remember my father has taught me to defend myself.  He tried to teach me the art of the sword, but when he saw my skill at hand to hand combat he told me to focus on that.  By the time I was 4 dad had meet a woman named Eva and they soon fell in love.  When she moved in with us she immediately starting treating me like her own son.  Not long after my 5th birthday when mom and dad dropped some interesting news.

"Izuku come here please" I heard dad call from down stairs.

Upon arriving in the main living room I saw mom, dad and a couple I didn't recognize.  The man had dark green borderline black hair with freckles.  The Woman had bright green hair with emerald eyes.

"Mother, father what can I do for you" I asked.

"Well first let me introduce you to our long time friends the Midoriyas.  The woman Inko is a friend of mine from before I met your father"  mother replied happily.

"The husband Hisashi is one of the first humans I became friends with after i rebelled against the underworld."

Before I could speak the woman, Inko I think her name was hugged me while rubbing her cheek against my own.

"Oh my god he's so cute!" Inko squealed while hugging me.

"Now Izuku the reason we called you down here" mom said with a soft smile.

"Yes mom?"

"Your going to be a big brother" she said while waiting for my reaction.

"Big brother?" I asked which got nods from all the adults.  I couldn't help the smile that split my face.  After that the Midoriyas stayed for dinner, during which I found out I was named after Hisashi's older brother who passed away do to an accident.  When our guest left I really threw myself into my training so that I could be a protective older brother.

I went to school among humans during the day.  When I got home I would spar with dad before doing homework.  After dinner I would train my stances and fighting styles, and like that time passed.  As days turned to weeks, and weeks to months mom began to show that she was carrying a baby.  When dad found out it was twins he was ecstatic.   Without realizing it 9 months had passed and I was holding the older of the twins.

"Dante" I said towards my brother.  Looking over at dad who held the younger of the two.

"Vergil.  I'm so glad I get to call you my little brothers."

Short I know but this chapter was meant to build the setting.  I want to thank my friends over on discord who helped me really think this out.  You guys rock!  Next time things get stylish please look forward to it.
