This Comic's Cast:

The point of this story being that I just ruin everything I touch. No hero is truly heroic in my world. They all have their moments, but they're all also flawed. Flaws are interesting.

The Ninja has the crystal because Ninajs (in Final Fantasy) come from thieves, and thieves would take the crystal. It's a very Darkmoon thing to do as well, but then he apparently is not only a Red Mage but also a thief.

Plainly Darkmoon's been working the job classes.
 
    

When evil spreads across the land, and darkness rises and the monsters roam. When the creatures of the night make beautiful music, and the things that go bump in the night go bump with greater enthusiasm. When the world is in peril and is in need of a hero...

These guys are, sadly, the best the world can hope for. These are the adventures of the heroes of CVRPG. They mean well, they try hard, and occasionally they do the impossible...

They actually do something heroic.
