Dream : Fantasy World

I was someone in some one's body.
A girl with long hair and all the attractions she wants from her school.
The school have lecture halls equivalent to university.
The teacher is teaching magic subject....
I don't understand any of it.
I don't know who she was.
Then, the bell rang...
Off she go from the isolated seat, she's like a snow queen.
Walking off alone, out to the forest...
She sense something off the bat, rushing in and destroying the demons in no time.
I couldn't even react to it.
Right in front, the scenery of my life - beautiful lake stretches across crystal clear..
There lies a mystical beast...
