As in the first season, of Puchimas! Petit iDOLM@STER, I like the Puchimas!! Petit Petit iDOLM@STER Hibiki more than the Hibiki from the regular iDOLM@STER anime. This is mostly because in the regular anime Hibiki is sort of a gag character with pretty broadly drawn defining characteristics, and they never quite worked for me in that context. Frankly, I find Hibiki's pet alligator harder to accept than believing Takane might be from the moon. (Speaking of which, Takane from The iDOLM@STER TV is eccentric and mysterious. Puchimas! Takane is a nutjob.) Hibiki is a gag character in Puchimas! as well, but every character in Puchimas! is a gag character. Curiously, Hibiki's defining role as a gag character in a non-canonical gag anime is not her canonical gag from the canonical non-gag anime. (This is my way of saying that "has a lot of animals" is not Hibiki's primary attribute in Puchimas!!. Rather, Hibiki takes the role of the beleaguered straight man, constantly vacillating between moments of incredulous Takane-inspired despair and regular moments of more conventional low-level suffering. Hibiki's affectations are influential enough that I've caught myself mimicking her exasperated sigh during darker moments of comically bad fortune, to tell you the truth.
So what about Hibiki from the games? I can't give this question a straight answer because I don't actually know all that much about Hibiki from the games. In fact, I'm only familiar with game-type Hibiki from Shiny Festa and Internet videos. Regarding the former, my lack of rhythm prevents me from advancing too far in the game. With regard to the latter, I've only seen a few game-play clips from the proper games; mostly I've just watched all-singing, all-dancing performance clips. As far as those are concerned, Hibiki, Takane, and Miki are all equally valuable to me as members of Project Fairy. That really is a well-balanced and nicely harmonized trio. Best project. Best fairy.
