Description: She is an elf. Blond hair, armor on her chest and her shoulder. The symbol on her forehead means that she is the "chosen one".
Past: her whole family got put on fire and she believes that her brother, in order to save her life, he sacrificed his life for hers. She is out to find who killed her family, but before that she needs to learn to fight well enough. So she seeks out masters to teach her some fighting and defensive skills.
Family: She doesn't know that her brother is still alive and her parents are dead. So the closest thing to her as "family" is her friends.
Things about her: She dresses in different clothes to hide the mark on her head, also to surprise people that she is not some poor defenseless girl, but skillful fighter.
First time she meets her brother: Seitri is walking and meets a gang of 9-15 people. She is exhausted from fighting an earlier gang and decides to let them take her. Then her brother, Scythe, was the leader of the gang. They become enemies, but they still do not know that they are kin.

Description: She has marks on her body. (face, ankles, neck, and forehead) She's from a tribe, Ina. She has marks on her body because of the tribe. The one on her head means that she is the chosen one. She also has a cape that can block her from being burned. The thing she wears on her chest is an heirloom.
Past: She was banned from her tribe and travels w/ her best friend, Cliaf, that was banned w/ her.
Family: Her mother died when she was born and her father works very hard to keep the family alive.
Things about her: She still dresses in the same style from her tribe, because she doesn't want to forget the tribe even if she was banned.
How she meets Seitri: When Nirei sees Seitri hurt, she heals her using medicine from her tribe. Her tribe forbids them from even seeing an elf, because decades ago they were enemies w/ them and went to many wars w/ elves. She told Cliaf about the elf and he agreed to help her. The tribe found out that they wre helping an elf, so they got banned.
Tribe Life: Her hair is exotic because no one else in her tribe has blue hair, not even her parents. She also has the mark on her forehead so the people there mostly ignore her. She is thought to have a curse on her. She only has one friend. (before the other chosen ones) and that friend is Cliaf. They were friends since they were born. (later Cliaf falls in love w/ Nirei, but she does not think about him like that. She has someone else in mind.)

Rengi:

Age: 22
Height: 5' 5''
Weight: 130lb
Weapons: he has this ability to make any liquid into any shape he wants it to be and make it solid. But it will turn back into whatever liquid it was before.
Past: Rengi works for a very powerful demon, Ihsus (read it backward..). Why? Well I am going to tell u right now... He has always loved his parents very much, when he was 10, he killed his parents. His parents were controlled by Ihsus, a demon seeking for more power. The same demon he was working for. The demon transformed Rengi's parents into monsters, and he thought that the monsters took away his parents, so he killed them. When they died, they turned into their original form. Rengi was very confused and mad at himself that he wanted to die. He buried his parents then slit his wrists. Halfway dead Ihsus closed his wounds and promised him that no one he loved would ever die and he would never be sad again, under one condition... That he will be loyal to him. They demon wanted Rengi to be familiar w/ powerful people and then find out their weakness is so that Ihsus can suck their energy and become more powerful.
Family: ˇ°twin brotherˇ±
Things about him: He always has ^_^ eyes unless he is extreamly mad or very serious. He wears a headband to hide the mark on his head. (Ihsus told him to always wear that)
