Please Save Me.

The Sole Survivor.

Alice and Lucy was dispatched into a mission to accompany the army in killing the Beasts down the land. They were the weapons of the army, no wonder why they were dispatched. It didn't take long, but Alice had collapsed in battle. The Carillons are weapons that take their users life force. Lucy came home carrying Alice on her back, they were exhausted and took a rest.

The next day, Alice was so full of energy that she is even able to shout after waking up, seeing her like this, I asked her a question.
"You're feeling better now, I take it? Why don't you tag along for morning exercise?"
From morning exercise, what I mean is, training with swords, dueling using the Carillons.
"Alice, let's see how good you are at handling these weapons. Bring it." William said.
"Huh? We're the only ones who can wield the Carillons, you can't..." Alice said and confused.
"I wouldn't be so sure, maybe I can use it better than you" William answered immediately,
"Oh really? I won't hold back." Alice answered back.
The fight was clearly one sided. She was on the offensive and I'm on the defensive, but it didn't matter because after all, I was one of the strongest warriors before the humans were wiped out. Our duel took about 2 minutes long, and she wasn't even able to land a hit on me. Lucy was watching our battle, after our duel, I suddenly became dizzy and collapsed on the floor and she saw me cough up blood while I was unconscious.
Lucy brought William to the clinic and tried to heal him with magic, she was surprised when she examined his body. There were full of scars, so many broken bones that his body can no longer keep up, his organs were barely functioning too. Two days had passed and he finally wakes up.

"Oh you're awake now? What happened to you? I examined your body and it was full of scars and almost all of your bones are broken and your body cannot keep up with it anymore, your organs are barely even functioning. You will die if you keep abusing your body, you don't even have to fight because the girls are the one's responsible for the battles against the beast." Eleanor told William.

"I didn't mean to keep it, but I am from the human race. The human race that turned all races against ours, the race that kept fighting other races, and then we were wiped out, along with the life on the surface, and I'm the sole survivor." William answered.
