Okayu knows, that people are horny for her and she knows how to tease them. Just follow
>>7426882 When the new costumes were announced, she was very nervous, but step by step she went more for the GFE and with her slut costume, she topped everything before. If you take a look at the fanart produced since then, most images use her new costume in sexy poses. I'd bet, Okayu's exactly calculating how to squeeze more out of the onigiryra.
Someone mentioned a few weeks ago, that the talents can request stuff such as props from cover. Just take a look at Fubuki's Sukonbu mascot. She created and introduced it on her own and people love it. Personally I like it much more than Korone's listener-san because people really identify with that cute character. Perfect for selling, right Cover?
