I think HIM & Aku's form of "bromance", needs to be redefined some. In fact, I'm still under the impression that Aku has no original gender to begin with; And as for Aku showing off his feminine side to HIM, he apparently could care less. Whoever it was that predicted this outcome with HIM being joined in the hot-spring by Aku's female form, props to you.
As for Chi, this whole shape-shifting ability of hers, should provide her with a new outlet to explore in the meantime. Even if it's only for a little while, it's better than her constantly obsessing over Mimi all the time. Her reaction to her transformation, is all to amusing. "SUGOI" indeed. Yes Chi, it is awesome. At least it's more awesome than her diet (that judging by all the junk food she has on hand), which is way off for someone of her figure. She must have one hell of a metabolism to handle all that she eats.
