Intro
With his usual playfulness nowhere to be found, looking truly flustered.
Uh... hey, guys? I'm really confused right now~...
Scratching the back of his head similarly while looking at Nagumo.
Well, that's what I was gonna say~ Who might you be~?
Resigned. He doesn't even try to understand anymore.
