Yes, when i got your answer and after reading the other guys one, i had to realize that the circunstances were different, in any case, they DO can give you back a toon, but talking about the circunstances...in mine maybe there is a lower chance to get my characters back.
I won't make a problem if that is, since i didn't lose that much talking about characters, the only thing that bothers me is that i needed them for a better Sacrifice grade (lvl VI), i guess i did it with some 3* and i got a lvl III or IV sacrifice, the rewards were some skills shards and warrior souls. So it helps if they can give that few characters back to do the things good if i get the chance.
