During the transport to the Ninth Officio, Mordred complains about being forced to use a public train. The Marshals reprimand her to deal with this necessity, stating that they can write a formal complaint after preventing the end of the world.
After the transport from the Ninth's teleportation facility, the Black Templars and Culexus group are scattered throughout the hellish battlefield they arrive in. During the fight Mordred loses her nerve and has to be harshly rebuked by Alondight to stay in formation.
For their final plan to take care of Warmaster Kharn's witch that stands between them and the still sleeping Walpurgisnacht, Mordred is to conduct a sneak attack, hidden by two Culexus while the rest of the group charges in from the front as a distraction. The Pendragon's Sword of Promised Victory is the key element that will eliminate Walpurgisnacht.
Enyo asks if Yuma and Cavefish are ready and orders a white clad Templar to give them any ammunition and rations they can spare. Meanwhile Mordred keeps sitting on a pile of skulls, sword clenched, ignoring everything around her while Enyo grows angrier with each passing moment.
She eventually starts talking by complaining about her vanguard consisting of a gorilla and a child in gimp suits and that the High Marshal must either want her dead or be a fool. Enyo growls that they are going to follow the High marshal's plan and tells her to finally prepare herself.
However, Mordred matches Enyo's growl, telling her not to talk to her like this before angrily pointing at Yuma. She starts to blame her for jeopardizing the mission like Malal said, points out how she showed up two hours late and still wears the cross of Emperor's Champion. While Enyo tries to reign her in, Mordred rises, unsheathes her blade and shakily points it at Yuma, claiming the Culexus is unfit to bear the insignia.
Yuma pushes the blade away with one finger, complaining that she should wait to be sanctimonious until after they are all dead, mentioning that her family name must mean little to her if she makes a fuss like this. Furious, Mordred tries to assault her, but before she can lift her sword again, Cavefish catches her in a crushing hug, completely ignoring the Templar's shouts and struggles.
The huge Culexus lifts Mordred up and uses her large gun to smack the struggling girl's rear like punishing a child, happy to see that it seems to be working. Yuma turns to apologize to the Templars for shaming one of their own, but notices that they are smiling in amusement and satisfaction, murmuring about how they never thought of disciplining Mordred like the spoiled brat that she is.
Mordred eventually stops struggling and quiets down. Suddenly a huge winged daemon drops down, crushing Templars and one of the remaining Culexus under his feet. Enyo pushes Yuma away and shouts at her to get to her designated zone while the Templars deal with the enemy, raises chainsaw blades from her mechanical arm and charges toward the daemon. Cavefish, still carrying Mordred over her shoulder, pulls her friend away and they run without looking back, except for the crying Templar.
After a while, they stop to rest and prepare for the stealthy part of their mission. Looking back, they see the shades of Templars still fighting the daemon. Mordred sobs that her sisters told her the Crusade was heroic, they never mentioned seeing comrades get killed and eaten by things that should not exist.
Yuma explains that a few people sacrificing themselves to save billions is highly heroic and that stories usually leave the part about dead friends out. Mordred replies that the Black Templars are supposed to return home alive instead of being killed without a chance to even draw their blades, slaughtered like cattle.
After a bit, she asks Cavefish to let her down to walk on her own, assuring that she will play her part. The pair of Culexus agrees and asks about her Sword of Promised Victory. Mordred explains that it is a technique passed down in the Pendragon family that focuses the blessing of the Blessed Lady and the First knight to a devastating effect. She channels herself through her sword to gather enough energy to release it in a wave that travels in a straight line and only knows destruction.
When Yuma asks how long she needs to charge up, Mordred lowers her head and admits that she needs five minutes with her current level of training. Once that time passes, everything in the path of her blade will die, even a monster like Kharn.
After a few more minutes of walking, the group arrives at the designated area. Yuma calls Alondight, who tells her that they will start in five minutes and asks the Culexus t keep Mordred safe until they arrive once the deed is done. Before Yuma can respond to the breathless High Marshal, the connection is cut.
Mordred starts her preparations and chants a lengthy spell, amber lightning gathering around her blade. Moments later, the Black Templars begin their charge, and just as planned, Kharn takes the bait and rises from her throne, confidently walking toward the group of knights. While Mordred begins charging her power, Yuma and Malal fully release their suit limiters to create disintegrating blasts of anti-magic for whatever comes close.
Kharn obliterates the Templars with ease, her prowess even greater than before and completely lacking in the Warmaster's playfulness. While the dying knights try their best to kill the monstrosity, Kharn laughs and turns around, raising her black blade toward Mordred's building lance of energy in mockery.
Alondight screams at them to abort and run, but Yuma decides to stay and orders Cavefish to put up a shield. Their combined strength is easily shattered by Kharn's assault, sending feedback through their bodies. Their suits already damaged, the pair puts up another shield to block the second attack and as it shatters again, Cavefish falls to her knees.
The huge Culexus pulses weakly that she is in pain and can't see, but Yuma roars at her to put up the shield one again. Staggering back to her feet, Cavefish does as she is told, but collapses from the third strike of the black blade.
Yuma registers her suit's notice that Mordred's five minutes are up and turns to her, shouting the order to kill the witch. However the Black Templar staggers back, eyes focused on the giant witch, drops her sword in terror and runs away as fast as she can, screaming for her family.
Malal appears out of nowhere, wielding a rosewood bow with a brightly burning tip. She fires a single arrow and defeats Kharn's witch, miraculously reverting her back to human form. Meanwhile Mordred escapes, hiding herself from the Templars regular search methods by using her armor's special traits. However search teams are already looking for her to make sure she pays for her transgressions.
