I would be lying when I say that the world of solo leveling is not appealing. The world of solo leveling is indeed appealing with the action and essence of leveling up and growing stronger by the minute. However while the essence of solo leveling being appealing is the fighting and overall action. The true youth and strength of solo leveling is that the many shadows and ranks that our main character has is very complex and confusing. The strength of this power the mc has is that he can summon shadows who are far stronger than him and other hunter or person out there. The levels of ranks and power these shadows who bow to their leader the mc of solo leveling is straightforward yet so hard to understand it takes even a fan of the series hours to understand fully.
The ranks are as follows
Standard base shadows
(Shadows who are not too strong and are There for numbers)
Normal grade
(Foot soldiers or foot shadows)
Elite grade
(Strong as standard B rank hunters)
Knight rank
(Strong as A rank hunters and are normally given names by the main character)
Elite knight grade
(Strong as S rank hunters)
Rest of ranks are above the true strength of any hunter
