Rather than "not being a target of the barrier", isn't it more like "they're so overwhelmingly strong that it doesn't affect them"? The demon, though he was weakened, could also enter after all... =P
Using Karkinos as a shield without his consent is terrible, even though his defensive capabilities are quite high. Lufasa getting stuck with that yuri yandere, that must be terrible.
LOL I love that Sagittarius was smoking a cigar... @Melkesjokolade2 As I recall Brachium is supremely powerful yes, but it has a large build up time and is not suited to be used against highly agile and mobile opponents. It's basically a "fuck everything in a single direction beam of death" but everything else besides that one direction is fine. So given how fast this guy is he could easily avoid Brachium and thus there would be no point besides causing massive damage to the surrounding environment, which would not help accomplish her goals.
If the elixir can cure the disabilities of the remaining 3 heroes then why the hell hasn't the mc thought of using them? It would be helpful if she could get those 3 as backup and make sure that she won't have to keep interfering every time they have a problem they can't handle themselves.
