Man, I was screaming "No, Yotsuba! Don't think well of that jerk. Can't you see Nino's 'player' detection alarm going off like a banshee?" But she pulled off superb fake-out when she picked Fuutarou for her partner. (Wait! Is that how it's gonna go down? Yotsuba just uses an executive order to claim Fuutarou?)
On another topic, this story could turn into 'Classroom of the Dead' if the other students keep pressing Miku's jelly dispenser. And Itsuki could be part of the body count if she isn't careful.
All that said, this must not be a high school for the academic cream of the crop if all these bozos can't figure out the differences between the quints.
