Like I wrote on the casual thread TN was able to give really a Bankotsubo's vibe in her (at least for me): her clumsy/funny way to act, the sadistic side, the folklore new theme and the return of Bankotsubo's iconic moves and at the same time creating a new moveset (but of course for this we need to see more for it). And personally I totally love her voice, it's exactly what I would imagine for a female counterpart of Bankotsubo (of course with a seductress tip).
I'm pretty glad and I think that TN made a great work so far in the creation of an alternative to Bankotsubo - they could create a male, but in the end the Female Tengu idea was too much popular to lose the chance.
About her latex outfit, personally I saw the thing very indifferently: the latex suit is a sexy fetish thing related with the dominatrix, so girls with a strong personality and a sexy attitude (as in DoA could be for example Christie but not Ayane showing different cliches). TN giving the outfit to this character want emphatize in a sexy way this side of the character: it was needed a such outfit? For me no, but with this I don't think that we got something exceptionally out from the sexy standards of DoA5, overall considering the other outfits already included in the game.
