HmphYou thought you could frighten Sayaka-chan?Wanna try it?Okay~You like roller-coasters, right?As if!You're not gonna refuse it, right?KyoSaya in the roller-coaster manga*smirk*Sayaka, y'know?
I heard a rumor that there was a veeery scary roller-coaster nearbyToo bad! I'll gladly ride it with you!
Both these lines are parodying the meme "Kawaii onna no ko da to omotta? Zanen, Sayaka-chan deshita!" (You thought it was a cute girl? Too bad, it was Sayaka-chan!)
In this case it goes "Kono Sayaka-chan ga ojikezuku to demo omotta? Zanen deshita! Mushiro yorokonde notte yaru wa yo!"It's a deal then
