I just read this series, haha what a great series. Admittedly I started because the premise was just too amazing to not read, but it's genuinely funny and interesting.
I can't see Keima ending up with Chihiro. He has zero feelings for her.
I also don't know what he's playing at, Chihiro is Ayumi's best friend, being ice cold to her is not the way to go. He should've confessed that he loved Ayumi or something at least. Now he just looks like a complete dick.
