Name: Ryoma Kuroyami
Species: Ajin
Gender: Male
Age: 19
Powers: Ajins are also known as monsters that can't be killed. Ajin limbs can be cut, they can be poisoned or anything can happend to them, but when they die, their body resets and any injuries or poisons or other effects on body dissapires. Although decapitated Ajin can 'die' as he lose memory about himself and personality (he may think about old memories as some dreams). They can also be defeated, if someone shots tranqualizer at them, they simply fall asleep (But if Ajin kills himself before falling asleep, then it has no effect). Ajin limbs regeneration is also able to destroy objects, no matter from what are they made, although Ajin needs to cut off his arm (They still feel pain and its painfull as hell), place their lost limb at wall or something they want to destroy and then kill themselfs. Antimatery appears for a second before new arm appears and destroy any object on a way, but for example, wall will be as destroyed as big was the limb (so it could just make small hole).
If any of Ajin body part somewhere exist and aren't too old, while his entire body stopped exist (By explosion or something) Ajin can regenerate from the place of this part (But if his old head stops exist, so it may count as decapitation). Due to Ajin's short existence in the world (They started to appear few years ago) its hard to say if they are aging and if they could or couldn't die from the old age.
Invisible Black Matter abbreviated as IBM, are the main source of an Ajin's powers. IBM cannot be seen by people who are not Ajins. As theorized, IBM is what allows the Ajin to replace any lost body tissues or nutrients, when an IBM oozes from the body of an Ajin when they're fatally wounded or when they're manifesting their Black Ghost. The origins of IBMs are still unknown as are their composition; IBM's are made up of intangible unknown matter that originates from an Ajin's body. Each Ajin has a different amount of IBM but nonetheless they all regenerate at the same rate - the only difference that the IBM concentration makes is how frequent they can manifest their Black Ghosts. Without training, it is usually 2-3 times a day for around 5 minutes.
Black Ghosts are Pitch-Black coloured Humanoids made out of IBM. They usually are 2 meters long and have extended physical abilities, as black ghost strenght is equal to how strong would be a person using 100% of their muscles strenght, without worry to destroy them. Black Ghost is really endure, fast and strong. It is also really hard to destroy as you need to destroy their head for Ghost to dissapire, however the easiest way to destroy black ghost is to use another black ghost (As Invisible black matter is a quite hard substance). More than one black ghost can be created, but then Ajin have to sacrifice either time of how long black ghost exist or daily amount of manifestations. If Ajin lose consiousness as their Ghost is still out, the ghost may go rampage or something before it dissapires. If an Ajin dies when experiencing a one in a life time heightening of emotions, they are able to cause a "flood" of IBM's and cause havoc by summoning multiple Black Ghosts that they can't control. 10-20 IBMs are generated depending on the density of the Black Ghost of the user. Such black ghost are usually agressive to the cause of emotions or everything that lives in general (Including their creator too) However, this is a very rare occurrence.
Of course black ghosts also have a weaknesses, without training you can't use them often due to a daily manifesation amount and time limit, also for some reason, Black Ghost seem to extremly slow down when they touch water (rain, river etc.) losing around a half or maybe even more from their amazing speed, their reaction is slowed down too and if something severe connection between Ajin and the ghost, then ghost will vanish. Ajin also need to have at least some space to manifest ghost and of course Ajin can't do much if it is immobilized. Ajin also can die from starvation or dehydration, they will ressurect after this of course, but they still will be hungry and gonna die again. They will live in endless cycle of dying and living untill someone help them and feed them in the same time they ressurect.
Backstory: Ryoma was living a normal live, he didn't stand out and had happy, loving family. Ajins weren't seen as a good beings. Unknown by humans, immortal monsters. They were experimented on every day with various weapons and new methods of killing. However, it was impossible to tell, if someone is an Ajin unless they die for the first time. Ryoma had an accident as he was hit by a car, the driver escaped and didn't see Ryoma ressurection. It was late at night so nobody saw anything too, Ryoma was lucky. As he know what was happening to Ajins, he hid evidences of his death and escaped from his hometown to live in the forest away from people. He was scared of what could happend to him and always remember this inhuman pain when car hit him. Ajins couldn't die, but they felt pain as much as humans. They do everytime they die...
Appearance: Ryoma has short, a bit curly black hair and red eyes. He has an average, a bit slim build and he is 5'7 tall. He usually wears black coloured clothes and leather boots. He also used to have slightly longer hair, but due to a fact that he could be hunted by goverment, he cut it.
Other: If something is wrong and he is too op in your opinion, please tell me.
RP Example: Ryoma woke up again in his small, forgoten by the world shelter that he built in a middle of the forest. Nobody should be searching him here, it was a good place to hide, river was nearby, he managed to find food, everything was okay. He sighed as he thought about everything that happend three days a go and wondered what to do now. Stay here until he dies? Could he really do this? He kept wondering about what to do and finally decided to go to a nearby town, buy a newspaper or something and quickly get back to his small hideout. He checked his wallet, that was almost empty and he could proudly say that he had enough money to buy a newspaper. He headed to the town and quickly found a small shop with newspapers, he brought one and saw his face on one of the first pages. 'This man is suspected to be an Ajin. If you see him, immidietly tell it to the goverment for the Ajin to be found and to give him a country protection.
"Country protection?.. Yeah, good joke. I am lucky that I decided to cut my hair earlier" Ryoma whispered to himself and escaped quickly to his hideout with his new newspaper.
