Since it's a crossover between Fate/Grand Order and Fire Emblem: Three Houses, there's bound to be epic moments from both across the story.
Per troping policy, all spoilers are unmarked. You Have Been Warned.
Main Chapters:
- Chapter 2: Even as a shell of his former self, Goetia shows that he is still a force to reckoned with when he gets involved with the fight against the bandits, easily decimating the bandits that foolishly try to attack him without much care. And he was focusing on Byleth at the time. His rescue made a good impression on the three lords that Edelgard and Claude consider recruiting him alongside Byleth.
- Chapter 5: Just from looking at him, Goetia easily saw through Solon's disguise as Tomas all while the false librarian remains unaware that his guise has already been saw through by an 'insect'. The only reason Solon doesn't get busted is because Goetia couldn't care less on what his deal is.
- Chapter 16: The Golden Deer formulate a plan to take out the Demonic Beasts that have been plaguing the town, with Claude using their house animal as bait to lure them for sheer irony. The class even managed to take out the remaining two beasts with ease without Goetia's help.
- Chapter 17: Picking off from the last chapter, Goetia finally decides to step in after the arrival of an Enhanced Demonic Beast (that was released to kill the Golden Deer on Thales orders). Although the Demonic Beast was able to absorb some of the spells Goetia threw at it, the former demon ends it by unleashing a huge pillar of light on it, burning it to a crisp.
- Chapter 21: Byleth asks Goetia to participate in a demonstration for her class. The Blue Lions seems skeptical on the prospect of ganging up on Goetia despite him being a powerful mage. Sylvain volunteers to go first and when it comes to the battle...Sylvain: Don't go for my face. It's my best feature.
Goetia: As you wish.
[Goetia taps his foot on the ground... only for a pillar of sand to shoot forth in front of Sylvain, slamming into his guts and knocking him back to the ground]
Goetia: (Blank Stare) Who is next? - Chapter 22: Continuing from the last chapter, Byleth tasked the Blue Lions to 'rescue' Flayn from Goetia in a roleplay scenario, where the class need to formulate a strategy to bypass Goetia and get Flayn. Of course, Goetia doesn't make it easy for them.
- While Goetia has immobilized the physical fighters of the Blue Lions, what he didn't expect was Mercedes using her earlier blunder in her first lesson by overpowering the gems she has, causing them to explode in Goetia's face. It didn't harm Goetia, but it was enough to distract from Annette to use a fireball to destroy the containment circle he put up to immobilize the majority the Blue Lions. This prompts Goetia to get serious.
- Chapter 23: The conclusion of the training, Goetia effortlessly trouncing the Blue Lions, though a few members did manage to take the mage by surprise.
- Point goes to Dimitri for managing to punch Goetia in the face in an effort to keep him busy while the remaining few rush out to get Flayn. The mage responds in kind by punching him with only one arm and two engage in a fist fight, with Goetia managing to win at that.
- Chapter 27: While fighting against a couple of crazed-driven villagers, Jeralt was able to disarm one of the peasants holding a Mad Enhancement sword. Although the sword was starting to influence him, Jeralt managed to resist the sword's corruption and threw the sword away without hesitation. It is justified that his Crest-infused blood played a part in helping him resist falling for the sword's influence.
- Lemegeton proving to be a formidable opponent when he decides to enter the battle fray. He easily demonstrates his control over the berserk villagers by ordering them to attack everyone except Jeralt, Seteth and Alois and proceeds to take on the three, soon overpowering them.
- Near the end of the chapter, Lysithea is wounded and Byleth is pushed to her limit. Goetia, who is sensing that Lysithea's life is in peril, attempts to remain neutral in his stance to be an observer to this mess. But when it becomes clear Byleth cannot rewind time anymore, Goetia flips a desk in rage and proceeds to teleport to the battlefield. And he makes it clear he's very pissed at this development.
- A villainous one with The Reveal that Demon God Sitri was also in Fodlan and managed to possess Aelfric due to his desire to resurrect Sitri Eisner acting as a life line for the dying Demon God. Sitri then absorbs Aelfric's personality and memories, managing to act like the Cardinal for the past few months without anyone suspecting a thing. Not even Yuri, who was forced to work for the real Aelfric to get the Chalice under the threat of his mother's life, noticed any changes —taken aback when the Demon finally reveal itself, throwing off his contingency plans he had for Byleth when Sitri kidnaps her along with the rest of the Ashen Wolves.
- Goetia wasting no time in confronting the despairing Rhea regarding her self-contradicting actions over the past centuries, pointing out the flaws in her decision to neglect Fodlan in favour of handing it over to Sothis along with asking her on why is she willing to do so much for humanity in spite of what they did to her people.Goetia: Why? Why go through all of this effort, all these long years of struggle, why go through all of it to just…abandon it all? It is utterly pointless. In returning Sothis you would have rendered all your sacrifices moot. Humans helped in the near extinction of your race so why did you do so much for them?
Rhea: Because..I…I don't know… - Chapter 104: Goetia confronts one of the undercover Agarthans in the Monastery, namely Kronya, to find out more of ancient Fodlan's bloody past from their perspective. He then proceeds to terrify Kronya into submission by breaking her wrist and paralyzing her with a magical wire wrapped around her brain stem and forces her to work as his spy for the Agarthans by making her sign a binding contract to not reveal this encounter and to not hurt any of Goetia's allies.
