i also read the official at webtoon (it's free too, so i'm suggesting ppl in this platform reading on webtoon to support the author) and i think the bonus episode itself is pretty important since the author explains about ability and how the tier works.
Why is the bonus chapter missing? It pretty much explains there the hierarchy, ability etc.
Can't get over the fact that John's ability as a low-tier is SASS *crossed out & N/A*
Nothing is confirmed yet whether he was really a king or whatever but for now being a Sass Master or King of Sass ain't that bad at all XD
