Dark Angel Izuku (IzuHarem)

Prologue

At the same time as quirks started appearing so did the angels and demons making demi humans with either angel powers or demon powers on top of their quirks making them much stronger, 40% of the population has angel powers with their quirks, 40% of the population has demon powers with quirks, 10% of the population has only angel or demon powers and no quirk, 9% of the population has no powers or quirks, and the final 1% of the population has both demon and angel powers with a quirk. Izuku Midoriya is the 1% of the population since he was born with angel and demon powers and a quirk that most would find useless.

We meet our protagonist for the first time at the doctors with his Mother and Father Inko and Hisashi Midoriya. Inko is the angel Supreme and has the strongest healing abilities while Hisashi is the demon King with the strongest Dark Magic.

Doctor: Mr and Mrs Midoriya I have some good news and a bit of bad news for you

Inko: whats the good news?

Doctor: young Izuku here has a teleportation quirk and has both of your powers making him a dark Angel

Inko and Hisashi: what?! izuku is this powerful?!

Doctor: Yes...but this is where they bad news comes in...Izuku's body cant currently handle both of your powers right now so they wont be active until he is at least 13 and has a stronger body

Hisashi: well at least we know he has them...we just need to train him to get stronger and use his powers correctly

Inko: yes he is still our cinnamon bun bunny and he will be the best hero ever

Izuku: Embarrassed Mom you said you would stop using that nickname in public!!!

Inko: oops

Doctor: Chuckling its quite alright. Now young Izuku your dream is to be a hero right? well i think you can be a great hero especially with a quirk like yours

Izuku: thank you doctor! we will get going now so we dont take anymore of your time. Goodbye

Doctor: Goodbye young man In his head what a sweet young boy...i hope he becomes the strongest hero one day

Timeskip to a few days later at school Izuku meets up with his friends bakugo twins, todoroki twins, Momo, Ochaco and Kirishima

Izuku: hey guys i got my quirk!

Ochaco & Momo: oooh! whats your quirk?

Izuku: i got teleportation! i can be a great rescue hero with my quirk!

Katsuki & Shoto: Nice izuku thats a really good quirk especially for Rescuing people

Katsumi: Izuku-kun will be the best rescue hero when he grows up

Shoko: agreed

Kirishima: what about your powers you gain from your parents?

Izuku: oh i got both but i cant use them until im 13 since my body is too weak right now

Kirishima: makes sense actually. your parents are the strongest Angel and Demon to exist

Katsuki: yeah hes right

Shoto: but the real question is...do you guys want to train together? we can help Izuku train his body to handle his powers

Katsumi, Shoko, Ochaco & Momo: Yes!!!

Katsuki & kirishima: sure lets train together!

Shoto: alright lets meet up after school today and start training

All: Hai!
