Edited Kingdom Subs
Please report any mistakes you find.
You can download all current subs from the Mega link below.
More importantly: Season 4 was announced!! We won't have any cheesy goodbyes here, this great season was just the start line, and the anime will continue in six months (spring 2022), so get that hype up! You can expect the Hi Shin Unit edited subs to continue with the new season of course (hopefully faster though).
Another thing you can expect is a batch of the whole season, that will be dropped soon-ish.
