People, I understand that the "CAVED" thing is funny, and considering what Keine dished out here, it's evocative. But it's dependent on her being EX-Keine. Even then, by the tag's description, it's meant for when she's putting her horns to use, or raping is imminent/going on. Please stop adding it back in.
