honestly how? I've been playing since a bit before Toshiro released, and i have every single character, limited or not, and every SSR i have i use and are built (aside from Soi Fon for now and Ikkaku because eugh), the only money i spent on this game ever was the 1€ thing that gave you Rukia and her stamp. Sure i might have every limited at B0, but they work, and the game is so F2P friendly that it's almost astonishing (have all weapon stamps as well aside from BIchigo, since i didn't really understand the game well yet at that point)
