Urgh another good manga with a disapppointed ending.

For me it was logical.
She asked for ALL children (so she had to be included) He took her memories so there was te reward ... And it was logical that their were looking for her. They were killing demons, so what is to look for a person.
The Lewis thing.. was a bit surprising but it was obvious that he is alive... I have seen far worse.

Would have been fun to see what happened in the Demon world but well well
