@Dyuu
you want to know something?
I did not see this anime yet,and these words came out of my mind without thinking!! I don't know about her or how to thiking!!
The luck came! Haha!!

Hmm, I think no one useless in this world.
She can't do anything becoz she don't want to do anything. She can do something if she want to. It's only a matter of will. 'Want to do or don't want to do'. That's all.

thanks for your comment.
