E-hentai tip of the gallery:

9) You can turn on many features, including "no ads", and access to more galleries, by acquiring "hath". See the feature list at /hathperks.php , and get your hath from /exchange.php?t=hath

I've been watching some of the red jacket episodes...hot damn, this bitch is always betraying Lupin...and he still gives a damn to include her in some of his successful heists.
