Why is this allowed?

what exactly do they call bigieu/belladonna's master in the collection, user?
i think in the translation he was just "the dark lord" "the demon lord," right?

Fan translation he was Demon Prince, in Collection he is The Dark Majesty.

Death Jester is a name that's stuck in my head for nearly 15 years...

sorry, Dark Prince.
But he is Dark Majesty in collection though.

I'm in the beast forest right now and the furry boss keeps kicking my ass. Do I just have to grind?

Dont cast stuff on him or use lvl 2+ techs, it procs counters.
