1 Main Info!

This is a side project that I wrote a long time ago cuz I never saw anyone write something like this story, so I said why don't I do the job, so here we are, also I suck at description don't mind me.

what if....what if female Izuku was the twin sister of Katsuki Bakugou!! But here is the twist!! She doesn't want to be a hero! She wants to be a support hero!!

She always loved building things and machines!!

Honestly, this story doesn't follow a particular timeline, it's just a fluffy story about Izuku and her crazy creations!

If you are interested you can check it out!!

So here is some of the background to this au!!

-Female Izuku (deku) is the twin sister of bakugou katsuki,

THE APPEARANCE:

-They don't look alike, unlike her brother Izuku has short fluffy green hair that she inherited from her grandpa .

her eyes are red just like katsuki, she is shorter than him, and they don't have any shared appearance except the eye's colour, they have different auras surrounding them izuku aura was more of an angel( but a devil on the inside)

(I love saying this...this photo was made by me, I used an ai, so mine, and man she's so beautiful.)

PERSONALITY:

-She never cursed or yelled like her mother and brother,

Izuku is pretty chill, She took the calmness from her father, as they both always sit down and drink tea or coffee while discussing other topics when her mother and brother are yelling and cursing at each other.

but if anyone hurt katsuki she will be pissed, she will make sure to send them to avenge her brother,

while katsuki will sit down and laugh his ass out as Izuku is dealing with the people who hurt him,

QUIRK:

izuku have the same quirk as katsuki, explosions, their power was on the same level so when they train it always be a draw.

Hobbies:

Even though they don't look anything alike, they have the same hobbies and fashion tastes, they both like to wear dark colours clothes, most of their shirts have a skull on them,

katsuki liked playing the drums, while Izuku liked playing electronic guitar, they always play heavy metal songs and music, which suited katsuki but no one thought that the 'angel' Izuku would love too, they didn't keep it a secret but at the same time they didn't tell anyone about it except their family.

they both loved seeing something explode and pulling pranks in their middle school, so they were quite popular there, and if the twins are bored they will want to make something explode, so the school tried to entertain them as much as they could so they won't set anything to explode in the school, one-time izuku and katsuki were bored so the twins made their school lab explode for entertainment, the lab was beyond fixing, so the school made a note to never let them bored.

Making weapons and machines, she's the one making katsuki weapons and costumes, and he's the one complaining.

THE RELATIONSHIP BETWEEN THE TWINS:

they are super close and touchy,

they always hug and hold hands in public without feeling shame or embarrassment,

people that didn't know that they are twins mistook them for lovers which made katsuki quite pissed,

she calls him Kat while he calls her Izu those two names are specially for them alone no one is allowed to use them except them if anyone does he will be met with the bakugous twin wrath,

katsuki adore his little sister a lot he loves her so much that he can't even get mad at her, he never screamed at her or yelled, he just pampers her endlessly, he's so overprotective of her not allowing any kind of danger to touch her, not because she's weak hell no she's strong even stronger than him, but he as the oldest twin who was born a minute before her took the responsibility for her happiness and safety, his personality changes around her he became a caring gentle brother full of love for her always smiling gentle and lovingly towards her, patting her head with a gaze filled with love and care

DREAMS:

Izuku doesn't want to be a hero like her brother she found being a hero boring,

her passion was building weapons and stuff and she believed that katsuki was the most suitable twin for the job,

izuku loved her brother and she didn't want him to be alone in the future so she wanted to become his exclusive support technical building costumes and weapons for him alone,

so she decided to go to the support course so she can learn everything possible to help her brother, to make the perfect weapon for him and to his quirk, so he wouldn't get hurt while using his quirk and can get over his limits without hurting himself,

She was the one who made the katsuki's costume to surprise him, making sure to include everything katsuki liked, so when Bakugou saw his costume when all might come to let them train, he realized who made it and smiled softly, his sister knew him like the back of her hand,

Also, I'm not very sure about including ships, tell me what you think.
