I like Mio's struggles. She face the difficulties alone and never let the fear came in her way. It's very difficult to survive when you know there is death in the door. A very few people fights. I read the story and wondered how can someone is so strong that doesn't frightened from anything.
The torture she gain the brutle behavior she survive, the question came in the mind how is it possible?

The all I got to knew the advice that whatever we got stuck in situation we should face it with braveness...
