Due to the nature of its lore, Solo Leveling:ARISE has a somewhat confusing tier system. All of its playable characters are monster hunters who operate within the confines of an official, ranked system, so each of them is assigned to a particular strata in the popular Solo Leveling anime and manhwa the game is based on. These rankings are usually fixed, but in at least one case, characters are known to be able to move up in levels as they gain power.
