Its stupid yeah, but its not rlly a solo leveling rip off. Thats like calling every isekai novel/manga a rip off of the other ones. Theyre in the same element, so of course they have similarities. The novel group for this theme are all super similar. I've read atleast 5 of these types that are from different authors that i would definitely call rip offs of the others if it wasn't a genre that overlaps so much. The only difference is, solo leveling got huge and only a few of these have been turned into manga so far.
It's not exactly the same. Almost all of the isekai-kinda-story have many resemblances and I feel it's a lit bit unfair if u called this one a rip-off.
Anddd.. Maybe u should try read the novel? I am on it myself 'cause at first I have the same opinion w/ you UNTIL someone (who read far ahead; like ch.200ish?) told me it was really worth to read. So yeah instead hurriedly calling this a rip-off or copycat, I'm gonna read the novel so I can make better judgement..
Let's just be good to any author out there 'cause they did their best to give us a good reads (▰˘◡˘▰)
It’s not similar just because they are the isekai game-like, the two solo protagonists almost have the same skill... but I won’t say it was a rip-off. The main plot of solo Leveling is to be stronger but the Ranker is to revenge for his brother. The setting are also different the Solo is a dangeon with a/b/c/d/e level if you are strong enough you can choose your level yourself but the ranker is to clear from stage 1 to 100. I think the protagonist of Ranker was inspiration from Solo and it’s just that. The plot is different.
Japanese have this plot for almost 10 years tbh.

I burst out laughing at ch 56. This is so obviously a rip-off of Solo Leveling.
The fact that the author is threatening anyone over copyright, let alone someone that was just doing a fan translation of the novel is....just so shameless. What a thick-skinned asshole.
