Griamore/Plot

Vaizel Fight Festival arc
He is first seen in Biron, having gone there after receiving a report that Elizabeth was sighted. Since the princess is nowhere to be seen, he quickly considers it a false report and to ruthlessly kill innocent citizens who reported about her. Noticing the trouble and incapable of being a bystander of such injustice, Elizabeth shows herself to prevent the execution of the citizen, which leads him to commend her courage and call it admirable. When she says that she would not forgive his injustice, he retorts, whilst lifting her up with a single hand, that what he had pledged his allegiance to was not the Royal Family. Suddenly, he is cut off from finishing his statement by Veronica's arrival.

At evening, he stays guard outside the room in which Elizabeth and Veronica are in, and worriedly questions the latter as to what had happened when Veronica gets angry at her younger sister. As Veronica leaves the room and orders him to guard Elizabeth inside, he then does so, despite him initially protesting that he was the former's guard. While he is guarding the room, King, using his telekinesis, makes the cup on the table fall down, in an attempt to distract Griamore in order for Meliodas to enter the room without his detection. The Sin of Wrath then defeats him in the fraction of a second, before the cup even hits the ground. Later, Veronica wakes him up, and he informs her about the events that had occurred, but is stopped from chasing them immediately by her, who cryptically states that they have already made their move. An unarmored Griamore, along with Howzer, is later revealed to have joined the fighting festival in Vaizel, in which he is assigned to fight against Matrona after advancing through the preliminaries. After the mysterious lady removes her cloak and reveals her resemblance to Elizabeth, Veronica, who is present in the audience, tries to stop Griamore from battling. He, stating that the moves Matrona had displayed during the preliminary were impossible for a frail lady such as Elizabeth, readies himself, and as the battle begins, is immediately punched by Matrona in the stomach with relentless attacks. He, however, stating that he cannot be defeated when his pride is wounded, uses his ability, "Wall", to create a spherical defensive barrier around himself, and states his intentions of using the barrier's omnidirectional expansion to push Matrona out of the ring without actually touching her. Glaring at Meliodas, he then declares in his mind that he will be the one to defeat Meliodas, since though he does not care much about the Deadly Sins' plot, the Sin of Wrath had disgraced him and caused him to disappoint Veronica, something that the Holy Knight considers to be absolutely not allowable. He then remembers an episode of the past, when he was role-playing as a horse, with a much younger Veronica riding on him as he does so. Seeing her being downcast, he notices her crying, as she informs him that she had overheard her father and Zaratras discussing about Elizabeth not being her biological sister like Margaret, but adopted, and to be originally from the kingdom of Danafor. When he asks her as to what Gilthunder and Howzer had told her about this matter, she tells him that she had not told either, as Gilthunder was busy guarding her sister, and Howzer couldn't keep a secret, and also that she told him since he always obeys her orders, and wouldn't not disclose this information to anyone if she ordered so, shocking him. In the present, as Matrona is struggling with his ability, Griamore reveals that it is a physical manifestation of his conviction to protect Veronica at all costs, and states that Meliodas will be humiliated by him next. That enrages Matrona, who, declaring that she wouldn't let that happen, destroys the barrier with a fully powered punch, and then punches Griamore in the face, which defeats him and sends him flying out of the ring.

Sometime afterward, Howzer heads to the place where Griamore landed, where he finds Veronica to already be helping her subordinate, and asks the both as to the reasons they had come to Vaizel. Answering the Holy Knight's question, they inform him that the child, and the man beside him, he had suspected to be Meliodas and Ban, respectively, earlier, were, in fact, the Deadly Sins themselves. Griamore then looks on, as Veronica explains to Howzer that their primary priority was Elizabeth's safety, and commands him to not make a commotion that will endanger her, then watching in surprise when the Holy Knight, in return, instructs them to not ruin the fighting festival, and merrily enjoys the fact that he will be able to personally witness Meliodas and Ban's battle. When Guila and Jericho begin their attack, Veronica, stating that the attack has begun before Elizabeth has been found, then instructs Griamore to find and protect Elizabeth. Veronica and Griamore soon discover Elizabeth, Hawk and an unconscious Meliodas, where Veronica then finds that the pendant she had given Elizabeth earlier is on Meliodas' neck. Griamore, without interrupting, watches as Veronica tries to drag Elizabeth with her back to the capital, and Meliodas suddenly regains consciousness and tries to convince Veronica that he will protect Elizabeth instead. Veronica, now convinced that Elizabeth has been brainwashed, recalls her and Griamore's meeting with Hendrickson earlier. Back in the present, Veronica chants an incantation, which causes the Goddess Amber, the stone on Elizabeth's pendant, to shine brightly, and Meliodas to disappear mysteriously. Griamore, dumbstruck that the method has worked, watches as Veronica again tries to convince Elizabeth that Meliodas is a demonic being, since only they are affected by the Goddess Amber. While Elizabeth continues to resist and refuse to return to the capital, Griamore, on Veronica's orders, forms a barrier around Elizabeth using "Wall" to forcibly take her back. As Griamore boasts on his barrier's strength, Ban suddenly wakes, and takes Veronica hostage.

Griamore demands Ban to let go of Veronica, and is relieved when Jericho's surprise attack on the Sin allows Veronica to escape. Guila walks towards the scene, and after Griamore releases his barrier around Elizabeth, extends her hand to help Elizabeth. Veronica, stopping Guila, declares that she will take Elizabeth. Guila argues that her duty also included a princess' protection, and when Veronica argues, dismisses her authority and threatens to use force. Griamore, unable to witness such insolence, surrounds Guila and Jericho in a barrier, and reinforces it when Guila tries to break through. Elizabeth manages to flee while Veronica's attention is focused on Guila. As Veronica chases her sister, Guila, much to his shock, then reveals that she was ordered to retrieve the princess, dead or alive. Despite frantically running towards the princesses, Griamore is unable to stop one of Guila's explosive mines from fatally injuring Veronica.

Griamore was in tears as Veronica was dying on Elizabeth laps, blaming himself that Veronica is dying, but Veronica then ordered Griamore to protect Elizabeth befoere passing away. Griamore then broke down in tears which set Guila and Jericho free and they attacked them. Griamore was then defeated by them and asks them what was their goal to which they revealed their plan. During Diane furious attack, Griamore protected the dead body of Veronica, Griamore was crying due to failing to protect Veronica and did not even try to protect Elizabeth. Elizabeth walked calmly towards Griamore and told him about a lake where Veronica and her used to play in when they were kids, and told him to bury her there since it was a place her sister loved. Griamore was surprised to see how strong Elizabeth had become and then realised that Elizabeth is crying to her sister's death but then stating that she will stop the Holy Knights for sure. Griamore later took Veronica dead body to her favourite place called Pernes to bury her as requested by Elizabeth.

His helmet was left behind for Hawk to claim it.
