Nozomi Takahashi - 高橋のぞみ

Nozomi is an initially-unseen character in the film, referenced as the "Takahashi-san" who was the only one to not show up to the Akatsuka High alumni reunion. However, through the film, she proves to have more of a presence, being someone pivotal in The Sextuplets' past even if they may not have remembered her.
