I'm actually more interested in Crest.
Maytag with likely get through her fear, possibly offscreen, only explaining in flashback how she did it. I don't see her as being a "dedication" type, but I do see her as having a great deal of drive for the short haul. That said, she might just say "#*%$ it" to an effort that is getting her nowhere, ask for her dimension bag back and leave. May would probably be my first choice, though, I'm just picking Crest to have a change of pace.
Based on what we know of Bernadette, based on what I know of the reality of this world as explained by Thin Man, I have a good theory of what happens next (now that I say this, our creator will likely try to Joss said theory). We know that the world isn't actually as it seems, that monsters called Qualia maintain the illusion called magic. We know that these swords are somehow toxic to magic, but if magic doesn't exist, this means that antimagic is not actually a type of magic (as in the sword is not "enchanted" with magic destruction, so the original assessment of it being a sort of "hypocrisy" might be off), but rather an energy (the swords might operate on a sort of EMP burst that shocks Qualia) or substance that allows the user to see the world or touch the world of the Qualia, possibly slashing them in midair or something.
Now, Bernadette could try hard to be something she's not, overcoming the "coddling" as the warden says. But I don't think she's gonna fight in the conventional sense anyway. And I think she is fine as is, actually at an advantage because she feels guilty and depressed.
Let me explain. Remember how with one sword, she was unable to block magic? It was because she was actively trying to survive. She was also because of that seeing the world as a world of magic. That is, she was actively playing by the rules of such a world. On the other hand, here, her feelings are raw and honest, and rather than a survival instinct, she will fight exactly according to her style. That is, she is in the right mindset to attack something besides conventional enemies. Which brings us to Bern's character.
Bern has a direct, functional style of sword fighting, more suitable for slashing objects or killing monsters, than cutting at humans. It is the same style she should be using to view the world, as something that is just a smoke and mirrors to be cut apart, revealing the truth. Normally, her survival instinct would kick in, as I say, and she'd be like "I've gotta survive against the magic/weapons etc." Instead, she is like "I don't care." Because or this, she can actually unconsciously transcend the "magic" of the Qualia and start to notice things don't add up.
Now, on the other hand, we have the three thugs she's against. As the warden said, these three have probably had this very drive to survive. Where has this led them? Well, naturally, they learned any techniques they could to win. That is, cheap tricks. Their power is based on magic, on smoke and mirrors, on appearing to have an edge. For most people, yes, the warden would be right, and she would lose. But she is wielding the exact best weapon against such things. The truth. The first one True Strike, is probably rather strong, but it looked like his sword in the last comic was possibly either getting his own magic boost (something like a Bless Self spell) or was itself a magic sword. Low Blow sounds like his fighting style is like Maytag's, using magic weapons and tools to quickly get the drop on people. And the Blue Fire sounds like a straight up mage.
In all likelihood, how this would go down, assuming she figures out how to properly use the swords? An embarrassing curb stomp battle, possible ending with all opponents completely disarmed and Bern walking away without having spilled a drop of blood.
Yea... as satisfying as that scene might be, that was alot of buildup for what might be little actual fighting.
In a side note, that was almost more padding and filler than the Naruto anime series.
