I think that was the smoothest HoloEn debut ever. Transitions were perfect, jokes were on point, the pet rock section panders well to the participatory nature of the audience (fucking /vt/ is getting into it even), and best of all she's actually going to stream video games.
Shiori was also good but far more outwardly nervous, a bit of scuff, and with affectations I know won't last when she gets more comfortable.
And yeah I think all 4 of them were predicted correctly.
