Ceremony
The leader of righteousness is the only one who can run this ceremony. Why? Because it's a very pure ceremony, and only those with an extremely righteous mind can run it.
Have him run your ceremony for you. Think about why he is so righteous, then think about an extremely righteous ceremony.

Sadly, the reason only the righteous can run this ceremony is because it's a punishment ceremony, where he pulls the cord to cut someone's head off via a guillotine (ぎ).
