You'll still get all four from logging in if you just want to place them on your desk and have them say cute things to you, but their gacha variants are better suited for running harder content.
Disclaimer: I enjoyed the game when I first started so I bought a $50 pack and a year later preordered Sitara. That was used to expand storage to satisfy my own autism, I've rolled everyone I have with tickets from grinding and gave up on a bunch of girls along the way. But if you don't have some self control then definitely avoid.
Not sure what's going on with the anon with the hateboner for a game that's basically promoting plamo on top of creating MD and Figma sets. Or the nerd that keeps being antagonizing with their info posts.
