Last Origin is ridiculouly friendly to F2P.
Getting character is really easy, only some of the latest ones requires significant in-game resource invetment to build but even them tend to become available as drops on the next event or chapter.
The only real paid content are the skins but you get enough "gems" to get several of them from time to time.
I haven't paid a single cent (mostly because I'd have to go through several hoops to pay them) yet I have all the skins I really want: All JK skins, miko Shirayuri, lingerie Alpha, office lady Beta, and so on. They even gave away the entire Horizon's maid outfit once.
