IC: She sees him and many black and silver creatures similar to him flying through the air of a strange planet, taking souls out of dead bodies and ferrying them off to another planet.
She sees him fighting against a red creature like him, with front facing horns, a tail, and a red and gunmetal mask. She sees Runa pin him, and hears him talking.
"Coron, you made me do this. I'll miss you, brother." She then sees him stab down into Coron's chest with his claw gauntlet as a tear falls from his eye, before Coron blew away as red dust, leaving only a shattered red gem in his place, about the size of Runa's if put together completely.
Runa looked back at Caeruleus. "Oh, sorry, Caeruleus. And unfortunately I haven't met your brother, so I don't know where he is."
