^ With Riho's first she is telling Kanon that her massage made her sleepy, then she presumably starts feeling Fuku-chan's skin and starts going crazy over her lol. She says she's my fuku-chan, don't take her away from me. She says lately she's started to feel like an wota, and many people have told her she's moe, and she keeps repeating how much she loves Fuku-chan's everything lol, until she says that she feels like a pervert. Then she goes out on stage and does her introduction by saying She's Sayashi Riho who is in love with Fuku-chan's hair and skin and wrists and ankles and face lol.
With Fuku-chan's it starts abruptly, but she says for some reason she didn't want to remember the Only You PV (I dunno why), then she's listening to Erina and Sayashi introing themselves, and laughs about Erina's reference to being a Gaki fan and says Gross, no way! to Riho's intro (above). Then she intros herself by saying she hates uni (sea urchin) and recites a little limmerick about uni that no one gets until she explains it.
