Lady Glutiva Chocolate was in FSR and Mariko became their spokesperson after that comic ended, as seen in this art(which was also the last piece of art posted on the Flying Suit Reiko site, from Summer 2004). If you're wondering how that happened Mentos bought the whole company and gave her the job as a gift..and if you're wondering who those people are, don't worry, older comic I'm just tossing this out as fanservice for the people who read Reiko.

>Mariko really loves chocolate, so of course for her White Day present Mentos had to get her something in that vein. He bought out Glutiva Chocolate, the super-premium company, and had them hire Mariko as the new "Glutiva Chocolates Girl" and star her in their advertising. It must be said that she really enjoyed it, although it all just went straight to her waist and it did get just a LITTLE embarassing wearing those clingy dresses on her new figure.
