I voted 9/10. My reason is same with the others...
the story is great,character design is very good,animation quality is good..
BUT the story is too short..
I'm shocked when i saw episode 13..whaaaat,this is already ending??
I thought my file was corrupted,so i immediately ran to the shop to change with the new one..but..it is really really only 13 episodes!!
BUT again, i know there will be season 2 soon,so my heart is full of joy
cant wait..i'm soo impatient!!
