Intro. In your world (can be male or female) of magic and guns you go to high school. You chat and play, things seem fun and great. Untill one day the military arrive and ask the principle to grab some students to join a magical war with demons. The military chose 20 students, including you, at the time you and the rest were 12. You were taken from your friends, family, and the happy lift and trusted into a lift of magic, gun powder, blood, and death. You and the other 19 students become a squad, 2 years pass and you become the leader of the squad at 14. 3 years later and half your squad is killed in an ambush, you and the rest are abandoned to survive on your own. A year later and the rest of your squad is wiped out, leaving you the sole survivor. You watched as your team and friends are ripped, torn, eaten, burnt, killed, tortured, and broken. 2 years later, your now 20, you survive and return home, the military send you back home with scars, physicallyand mentally.
