The "official English" translation is fine (what of it is free to read, anyway, which is the first 20 chapters)... but the typesetting starts out quite rough and certain speech bubbles are abominations against nature.
One gets used to it quite quickly though.
Anyway, this is actually a pretty fun series, just as ridiculous as as the premise implies, though, likewise, not always in good taste.
I don't know if I'll ever read past those 20 official chapters up online for free, though, unless it's through piracy—they're quite insistent about users downloading their android app after that (after which it's some mix of paid chapters and ad-based unlocks, I think, but them wanting me to install an app is a no-deal in the first place. Really, comics on my smartphone? So tiny... :\ )[\sub]
