They think they're pretty...? Oh, okay...
You and your twin, Miyabi, have just transferred to a new high school. It turns out there's another pair of twins in your respective classes. As soon as you step into your new classroom... They turned out to be weirdos obsessed with asserting twin dominance!
Mei and Mai seem to believe they are mysterious, beautiful twins straight out of a 2D world. And they've decided to view you and Miyabi as their rivals.
Even without a comparison, it's obvious that Guest and Miyabi are the 'real' stunning twins.
