I was watching a sad video about Sebastian, Claude, Agni, and Grell. Basically, it seems like it's years after all their masters are dead. But they're all still alive, seeming Sebastian and Claude are demons, Agni's the embodiment of Hindu god, and Grell's a death God.

It's basically them looking back on the time they spent with their masters (Ciel, Alois, Soma, Madame Red) and regretting not showing them enough affection and regretting all the wrong stuff they did.

It has Sebastian holding Ciel's ring in one scene with a far off expression, it has Grell looking at Madame Red's cinematic records, and Agni looking at one of Prince Soma's old tea cups. Then Claude is just hitting the wall out of frustration.

The line that gets me the most in this cosplay music video is "I love you, baby I'm not a monster" cause their masters never thought of them that way...

If anyone wants the link, I'll gladly give it.
