Yuusha To Maou?

What the heck is this series? And why can't I find any information on it or any of the characters on Google? And how is it related to Maoyuu Maou Yuusha?

1. Read the yuusha to maou wiki page.
2. You didn't look very hard since there is plenty of info on our own wiki, as well as pixpedia and other places.
3. They're based on the same RPG cliches. Otherwise, there is zero relation. (The wiki page probably links to it under "see also" just because people might get the titles mixed up.)
