Ah the nightmare arc? (Its literally written in the description. <ods don't shoot me please) Well. I kind of knew it existed so i guess this sequel was only a matter of time.
@Nep The LNs are still popular in Japan; there's already 11 volumes.

One thing I recall from the LNs is how much (IMO) the MC feels like an old-school shoujo heroine in some ways ; passive, wallflowery, shy, retiring, the type who bottles up all her troubles bceause she doesn't want to burden others.
Lmao the credit make me laugh "our Hero slave" . Thanks for the update , im curious about what kind of problem this arc Will be, a little spoiler about the problem please? Anyone who know , xD
