I'm awfully late to the party. Loved this episode.
I like watching a villain who is confident, but not acting in an overtly flashy way. There's a certain aura of coolness and maturity around Kaiki, in contrast with Karen's, oh so cliched and cute naďveté. "Ooh what's that? You came all they way up here to
punch me?" -Kaiki
I also love listening to Shinichiro Miki. Oh my god. We really need to get him, Sakurai Takahiro (Meme) and Kamiya Hiroshi in the same room together. I would probably die of the ensuing eargasm, though.
Hopefully Shaft wont hold back if Araragi decides to carry out his plan of transferring Karen's disease. Same with any other possible future siscon developments.
