Red is the real mascot and is on app icon when there's no alternative outfit or character character to roll for, Rosa never got this privilege
The first girl you get from the game is Misty, alongside Brock, but Rosa is the second one
Rosa is also the first girl to get a seasonal outfit, and the only unit with a continuous campaign that allows you to boost her to 6*EX (powercreep shite) without using your own items, she's present in many of the (early) story and events
Finally the name of her sync move (元気メイっぱい - Genki meippai) is a meme among jp artists, as it's a play on her japanese name that you can read as 'Full of energy' like intended or something like 'Energetic Rosa breasts' if you're horny
But all of this was for the first year of the game or so, nowadays she's forgotten by the devs, who are too busy jerking off to Lillie's third iteration.
