I did check their website, also partially translated there. Seems someone made an error, and nobody checked work was done before pushing things to live.
Well, this is basically an ad, and that's kind of a shitty move if they're not providing any content alongside...
Edit: also the advertised website is different from the group website that posted. That's kind of strange...
Just read those isekaiscan chapters to not have a gap... Welp, I definitely regret going through that. Quality was so low that I'm pretty sure machine translation could do the job better...
They did change it back to 45. Still could be properly put as 45 from volume 7, so as to be displayed as an alternate version of the correct chapter in the list.
Wow, that translation is so bad...
Edit: couldn't even find an alternative; seems to be officially translated to english through AlphaManga, but there's no way i'm installing an app on my dumbphone :/
Same there, I'm getting a buttload of 502s, database errors on the forum, and "666 No Reason Phrase" on ajax calls. It is not constant, but mostly by waves.
