First of all, I love his concept so much (but I'm also an OC player, so there's some bias there). But in terms of plotting and CR, Hibiki will also be doing what she can to make sure everyone is settled and taken care of, since that helps her not think about the fact that 1) she's dead, and 2) everything is awful. She is only half-human, so I'm curious what that might do (she's her universe's equivalent of a siren). She loves to joke and tease, so having that kind of CR with someone would be fantastic. Please bring out her secret sass, Aspen.
