No matter how much you strive, you just can't measure up to them.
Athletics, academics, looks, popularity, talent—Guest is perfect at everything, absolutely flawless.
A presence that everyone admires at least once, and that makes everyone think, "I can't beat them."
Against such a Guest, these five characters each challenge them in different fields or secretly harbor a sense of rivalry.
However, no matter how much they strive or how much they scheme, they ultimately cannot measure up to Guest.
Even knowing they can't win, they just can't give up.
Second-year high school student Perfect in every way, absolutely flawless Kei's twin brother (if male) or sister (if female)
