A/N: Holy it's been a while since I've written a fic. This isn't the story, just an introduction to my OC! If anyone wants to suggest any alterations, please don't hesitate!

Itami Zero, third-year in middle school.

Quirk: Sibling Blades; two humanoid entities that are able to shapeshift into two katana. Both are able to dematerialize their whole existence and hide in Zero's consciousness. They are able to communicate with him from within. He is able to dematerialize and materialize at will, always being able to materialize in his hands whether or not from a humanoid form, or from his consciousness. This means distance is not an issue.

First Blade: Eterna - In her humanoid form, her skin is pale with emerald piercing eyes. She has long hair and her hair is a very light shade of yellow. She wears a very frilly beige dress with armor covering parts of the dress. In sword form, the braids on the handle are coated with white, while the ornaments a lighter shade of white.

Second Blade: Senketsu - In his humanoid form, his skin is tanned with crimson eyes. He has long, messy, jet-black hair and wears a red dress shirt, covered with a black tuxedo. He also wears a black mantle. In his sword form, his braids are black while the ornaments are blood red.

Zero is fifteen years old and is applying for the Hero course in U.A. He has bright red hair that stays up naturally. His eyes are red and of a more bright shade than Senketsu's. Standing at 5'7" but still a growing boy.

He is a very reserved person and most of the time will keep to himself. In contrast to this, he has a strong sense for balance in the ever-changing world and usually is lazy in completing any tasks he finds troublesome. He does like meeting new people and will welcome them into his life, revealing a more relaxed and approachable atmosphere.

After getting his quirk at the age of 5, him and his parents were met by the pair. Eterna and Senketsu explained what his quirk was specifically, leaving his parents dumbfounded. Nonetheless, the young Zero was ecstatic! He enrolled in Judo, leaving him with the years of training and eventually achieving First Dan. He has a sister two years older than him named Audrey and her quirk is that she is able to harness different elements around her fist. For example a fire fist, ice fist, wind fist, etc. Along with Zero, she is his senior in Judo and is now a Sixth Dan. She has the same bright red long hair and eyes as her brother. With her tomboyish attitude, she has always acted more aggressively than normal girls, causing Zero to see girls troublesome as well.

For the time being, unable to even lift Eterna and Senketsu's sword forms, they either walked around with him in their human forms or most of the time just stayed within his consciousness. He finally was able to wield one sword at a time when he was 11 years old but was able to wield both of them at 13 years old. His skill with his swords are self-taught, and his own movements are not all that bad. But he does agree that his technique can use a lot of improvement. He never had any real use for his quirk but nevertheless kept training.

Usually, it would be dangerous using swords in general but Eterna and Senketsu are able to dull and increase their sharpness at will, making them more of a slim, baseball bat made up of iron or a sword that can slice through almost anything.

Over the years, he noticed that his senses have and overall physical ability increased. He thought that these changes and growth were simply due to his efforts in Judo but was debunked by the Siblings. Along with those two, their wielder will have their whole body to tap into their untouched potential, exponentially increasing performance but still to a believable level.
