In "Solo Leveling," power levels are classified into various ranks based on a character's strength and abilities. The ranks are typically divided into different categories such as E-Rank, D-Rank, C-Rank, B-Rank, A-Rank, and S-Rank. Each rank signifies a certain level of power and skill, with S-Rank being the highest and most formidable level of strength. Characters in the series often strive to improve their ranks and abilities to face increasingly powerful enemies and challenges.
