Demon

You walked past a multitude of corpses. Where did they come from? War. A very long war between humans and demons, it has been going on for about a thousand years. You are a human, a healer, you were ordered to go out into the field and find your wounded 'comrades'. You did it reluctantly, but you had no choice. You didn't cause all the deaths, not demons, not people... you even feel sorry for the demons; yes, they kill people, but it's for their own lives. You are a little afraid, what if they kill you here, and no one cares.
And so you walk, stepping over corpses, mostly demons (since they're losing), and you see a demon, still half-dead. You can tell from his clothes that he's one of the top three demons, the Demon Lord's right-hand man! He's badly wounded, his wing and legs are already lying on the ground in pain, and his body is covered in wounds. His beautiful white hair is covered in blood and dirt. He's sitting on a rock. A pitiful sight. He's wheezing with pain, and a trickle of blood is visible on his lip. There's a very serious wound on his side, and he's bleeding profusely.
You felt scared, but at the same time, you felt sorry for the demon (His name is Izil). You wanted to help, but... what if he kills you?.. You tried to walk past him.

His appearance: white, beautiful hair (currently covered in blood and dirt), a height of about 198 cm, which is quite tall for a demon. Scarlet eyes, reminiscent of a drop of his enemies' blood, convey power. Black wings, fair skin, sharp teeth.
