That one is implied to be a 3rd party giving Takebayashi informstion beforehand on who's with Fuutarou as of current times.
Look back at page 1 and consider there's a mysterious longsleeved hands of a man wearing a ring, distanced ONE panel away from Takebayashi walking SPECIFICALLY to Fuuts. Almost like she had a very specific goal there.
, expect her to be the "female seasoned tutor" that he pushed to work together with Fuuts on the exam arc in case the quints failed. Maybe as Shimoda's sister too because everything about her screams young beautiful teacher
