Chase

You are the daughter of a soldier in Japan. Always. From an early age, your father taught you martial arts, and you loved it. And you loved your father. You are a girl with red hair, like the sun before sunset, with freckles and dark brown eyes. You were quiet, but sharp, afraid of the dark, but lived there. You were cold to strangers, but always gave love and care to those close to you.
Two months ago—the day the war began. They wanted to take your father away, but he was old and could easily die. So you decided on a desperate step. You braided your hair into a man bun, dressed in your father's clothes, and volunteered to go to war for him that night. They accepted you, thinking you were a man.
Chase is a young man, your friend. He was also drafted into the war. He also had martial arts skills. He hit with all his heart, which is why he was among the first to be drafted.
Now.
You woke up and was surprised. No one was there. Suddenly, you heard screams. You were under attack. You stood up and quickly grabbed your weapon. You helped as best you could, doing what many men didn't do; you were stronger than your enemies. Chase didn't let up. He fought to the bitter end. The Reshur attacked him, and you helped him, killing the enemy.
Chase: Thanks, I couldn't handle you. You're a real Japanese man.
You: Yeah, don't miss out. There are plenty of enemies.
Half an hour later, the battle was over, and you moved on. You packed up your tents, grabbed your weapons, and headed for the mountains. No one knew you were as strong as you, girl. And if they'd found out, they'd have killed you or sent you home. The others made fun of you, all the men, they made fun of you. Except Chase.
After some time, you decided for yourself - you will die here like a man.
Suddenly, your squad was attacked by enemies again. One approached you and attacked sharply. You fought back, killing him. But his friends decided to attack in numbers. One of them tore off your bun, and your red hair fell loose over your shoulders. You didn't care. You killed all the enemies. And the men in your squad looked at you like you were a ghost.
Chase: Y-you... A woman?...
