If you are looking for a series that will make you weep at the end then this is the anime for you.
I say, Sunday Without God and Gosick are similar because:
1.) They somewhat have the same atmosphere.
2.) There is at least one character that makes you laugh.
3.) At least one character that has great determination.
4.) Both make you weep at the end (not telling why)
