Howzer/Plot

Vaizel Fight Festival arc
Upon being ordered to stop the invasion of the army of the Northern Barbarians, Howzer and Gilthunder arrive in the battlefield on a flying dragon. Both then quickly and easily defeat the entire army, with Howzer even questioning the Great Holy Knight, Dreyfus, after returning to the castle, if their "errand" just now was the predicted so-called Holy War, which, his superior assures, is not. When Gilthunder states his suspicions of the kingdom's unpredicted foe in the Holy War being the Seven Deadly Sins, Howzer expreses his disbelief in the Sins' strength. Dreyfus replies that the Sins are a grave threat, and proceeds to inform the two of Meliodas having destroyed Danafor. This greatly shocks Howzer, who then also begins a conversation on the "New Generation" of Holy Knights. Though their origins are mysterious, Howzer, optimistic as usual, only considers their benefits, and soon leaves, citing busywork.

Howzer is then seen to have joined Vaizel's Fight Festival when he stops Taizoo and Meliodas's skirmish. He is delighted that he is finally able to enter the tournament, and to be not restricted by work. During the preliminaries, Howzer is shown to be flinging a fighter, and after they end, is seen among the eight people who have advanced. In the main tournament, his first fight is assigned to be with Taizoo. When Meliodas and Ban, who have joined the tournament under the names, "Meliodafu" and "Baan", respectively, are assigned to fight against one another, Howzer almost discovers the two's identities, but dismisses them as Deadly Sins because of their obvious name changes, due to his naivety. Howzer observes Griamore and Matrona's first battle, speaking of Griamore's ability's power when the Holy Knight activates it. He is greatly shocked when Matrona manages to defeat Griamore despite his ability, calling the mysterious lady a monster. Afterwards, he battles Taizoo. Though losing badly, Taizoo refuses to give up due to his ego. Howzer, who has been using very little power, since he could kill Taizoo if he uses too much strength, requests his opponent to surrender, for Taizoo's own benefit. When Taizoo refuses, Howzer, forming a twister around his hand with his ability, defeats Taizoo, adding that letting the battle continue would be dangerous for his opponent. After the battle between Cain Barzad and King ends, Howzer finds Veronica at the place Griamore landed after being defeated and sent flying. Greeting them, he questions as to why they they have come to Vaizel. He is is then informed that the child and the man with a scar, he had suspected to be Meliodas and Ban earlier, were in fact the Deadly Sins themselves, much to his shock.

Greatly shocked by this information, Howzer questions the two of them whether they are planning to capture the Deadly Sins alone. Veronica states that her primary priority is to ensure Elizabeth's safety, whom they are searching in the first place, and commands him to not make a commotion and endanger it. He immediately turns around and runs towards the fighting ring, instructing them to not ruin the festival, and merrily enjoying the fact that he will be able to personally witness Ban's and Meliodas' battle. As he observes the Sins' battle, he comments upon its intensity, commenting that the two are "beyond monsters" for their great strength. Howzer continues watching the battle until its end. As his next fight with "Matrona" is declared, he expresses his enthusiasm to fight. When it is begun, Howzer turns to the side and points to Diane's chest, since her button was undone, much to the audience's disappointment, and Howzer's embarrassment. Howzer charges towards Diane, using his ability to form a small twister around his arms, and attack with it. Diane manages to dodge, stating that such an attack can cause great damage. Howzer agrees, and tells her to stop evading and be defeated, which, he says, will feel "great". Meliodas interprets Howzer's statements differently, as double entendres, much to Howzer's anger. Howzer, then, despite not wanting to harm a woman, finally restricts Diane's movements, and goes in for a punch, but finds that he is easily stopped. He, bewildered, cites Diane's earlier comment of his ability being dangerous. Diane explains that she had said so because she does not want the clothes she has borrowed from Elizabeth to be torn. In response, Howzer states that he can finally unleash his full power. Howzer, wondering if Diane is also a Deadly Sin, due to her great strength, then uses his abilities to form a large horizontal twister, warning Diane to flee or die. Much to his shock, however, she remains unharmed, leading to his confirmation that she is a Deadly Sin. Not giving up, Howzer manipulates the air to create a gigantic twister which covers the entire ring. He boasts that Diane would not be able to breathe inside the twister, and that she will be ripped to shreds if she tries to resist its centrifugal force. As he rejoices his victory, Diane uses a technique that appears to increase her body's mass, and uses the increased gravitational force to defeat Howzer from above. Howzer, collapsed, acknowledges his defeat, and states that he is honored to have been fought seriously by a Deadly Sin, not believing Diane's weak lies that she is merely a girl happening to pass by Vaizel. He confirms her identity when King addresses her as "Diane", with her then apologizing again, and walking away.

As Meliodas and Cain's fight begins, Taizoo, whom Howzer is standing next to, informs the Holy Knight that Cain's attire is the traditional armor of the Danafor's Holy Knights. After the dramatic battle ends, Cain walks towards the two, greeting and questioning them if they have more energy, which they confirm. Howzer then witnesses the battle between Meliodas and Diane, and is in awe of their strength - he proceeds to note that Diane was not fighting seriously in their previous battle with. Due to their whimsical nature, he begins to wonder if they are really a threat, but immediately decides that they are, after the Sins begin threatening to massacre Vaizel. He further develops a negative image of them, after he is deceived to believe that Guila's attacks were the Deadly Sins' doings. He later adorns his armor and wields his lance as he proceed to stop the Deadly Sins. He encounters Diane, declaring that he will be arresting her, believing that she is plotting to overthrow the kingdom. When Diane suddenly runs to the help of a civilian who was trapped under debris, Howzer notices Marmas walking towards him. Marmas quickly uses his ability to multiply gravity around Diane, who tosses the saved civilian to Howzer as earth beneath her collapses.

Howzer shows his discontent towards Marmas for putting an innocent person in trouble, but Marmas tells him that he is only following his orders to stop the Deadly Sins, and does not mind harming innocent victims during the process. He immediately grows angry at Marmas, questioning him who was the real criminal: Diane, who risked her life to save a civilian, or the Marmas who gladly kills innocent people. Marmas gets increasingly annoyed and challenges Howzer to fight him, when Hawk Mama suddenly appears and tosses Diane's clothes into the pit. After a brief moment, Diane climbs out of the hole and smashes Marmas with her fist. Howzer sees Diane unscathed, when the latter asks the former whether he is surprised at her true size. Astonishingly, Howzer tells her that he was not and is glad she was okay.

Diane then asks Howzer to take Marmas and the old man, and ran away which surprises Howzer. She then continues to ask if Howzer will try to capture her, but Howzer tells her that the Kingdom will be after them because of what happened to Vaizel. After Diane annihilates Vaizel using her full strength in the fight versus Helbram, Howzer surfaces from the rubble of the ruined town while carrying the injured man. He then states how powerful her attack was and remembers his earlier conversation with her. Howzer smiles at Diane and states that he wishes to meet her again and wonders how to report all of this to the Great Holy Knights, eventually disappearing using his cyclone.

Armor Giant arc
Howzer returns to the kingdom to report of the events at Vaizel and learns of Veronica's and Griamore's reported deaths from Gilthunder, who further mentions that Hendrickson's group has been increasing dramatically in size over the past few days. He ponders over how they should report this to Princess Margaret and Great Holy Knight Dreyfus, when Gilthunder tells Howzer that Dreyfus has locked himself in his private room.

Kingdom Infiltration arc
Howzer is ordered by Dreyfus along with Gilthunder, Guila, and Jericho to stop the three Deadly Sins who were infiltrating Liones. He briefly wonders if Diane is amongst them, but realizes that if she was, everyone would have seen her. Jericho begins quarreling with Howzer, but soon calms down when Dreyfus begins questioning if Helbram told them all he knew. As they enter Hendrickson's Magical Research Facility, he asks Gilthunder whether he had looked up to Meliodas as he taught him how to wield a sword, but Gilthunder replies that he was only taught the fundamentals of the sword, in a matter-of-fact way. The Holy Knights suddenly sense a subtle sound coming from the basement, soon discovering that it was Diane.

Howzer is astonished to see Diane before him, and becomes more and more nervous when Jericho decides to deliver the first attack. Diane straightaway swings Gideon, destroying part of the building and blasting Jericho away. As Gilthunder engages in combat with her, Howzer is hesitant, leading Dreyfus to ask him why he is not attacking. Under Dreyfus' direct commands, Howzer reluctantly enters the battle, using the combined skill Dragon Castle with Gilthunder. Diane was able to fend off the technique by using Ground Gladius, but when she attempts unleash it for a second time, Dreyfus easily blocks it and uses his ability Break to pierce through her chest. Howzer helplessly stands by the side as Diane is assaulted by Dreyfus. As Diane is being framed by Helbram for destroying buildings in the city, he and Guila decide to stop the Holy Knights from killing Diane. He remembers that Dreyfus had once told him, "The only time you should use your power is when you are sure of yourself", and decides that it is the time''. '' Howzer asks Guila if there was a chance of them winning which she denies. However, they do not give up, but combine their powers to attack the Holy Knights with Bomb Cyclone. As the storm ends, Jericho is shown to be completely defeated, but Gilthunder escapes, Helbram protects himself, and Dreyfus remains completely unaffected. Gilthunder sneaks behind Guila to attack her, but Howzer manages to block his sword which left Guila open to an attack from Dreyfus, but she is saved once more, this time by Gowther, who now joins their battle.

Howzer is surprised to see the Goat's Sin of Lust without his armor, who then begins a fight against Dreyfus inside his mind using his Nightmare Teller. When Dreyfus brakes free of Gowther's Invasion, Guila is shocked to see Gowther rendered unconcious, but Howzer points out that thanks to him, Gilthunder and Dreyfus were forced to retreat, leaving Helbram alone. As the latter questions of they really had the upper hand now, Howzer tries to attack Helbram, who then uses Call of Inferno to summon deadly smoke. Diane, who used the time bought by Howzer and Guila to regenerate a bit, stands up again to smash Helbram, making the dark smkoe vanish. Diane gives Zeal to Guila and tells them to leave, but Howzer refuses and says she should worry about herself rather than others. Helbram stands up again and pierces Diane's stomach using Killer Iceberg which puts her on the brink of death once more. However, before he can finish her off, King appears to save block the approaching attack. Howzer is surprised to see "Old Fart" again, but Guila points out that it was King, the Grizzly's Sin of Sloth, which surprises Howzer. Crying about Diane's condition, King approaches Howzer and punches him for failing to protect Diane until his hand starts bleeding and he is held back by the latter. King eventually desists from Howzer to fight Helbram which both Howzer and Guila watch in amazement about King abilities, calling him a dependable ally and fearsome foe.

As Helbram summons roots to kill Diane in order to torture King, Howzer tries to defend the unconscious giant, but in the end is no match against Helbram's power and is sent flying to Diane. To make sure Diane doesn't survive any longer, Helbram then lets his roots beat Diane once more, only to realize King used Chastiefol's eighth Form to protect and heal Diane slowly. Severely wounded, King looks at Howzer and calls him lucky to be near Diane when the healing shield appeared, just like Guila, Zeal, Gowther and Jericho. Howzer smiles and notes that the Deadly Sins are too kind for their own good. After witnessing King defeating Helbram, Howzer asks King of the Sins' presence in the kingdom's capital, only for the Grizzly's Sin of Sloth to tell him of Princess Elizabeth being kidnapped. After Great Holy Knight Dreyfus attempts to behead the Fairy King from behind, Howzer expressed surprise but is relieved as King easily overpowers Dreyfus and manages to render him motionless. As King interrogates Dreyfus, Howzer is shocked by the Great Holy Knights' plot to resurrect the Demon Clan and use Elizabeth as a sacrifice, although Guila states that Hendrickson is the true mastermind behind this plan and only using Dreyfus.

While carrying a still-frozen Gowther, Howzer later tries to convince Dreyfus to join their side to stop Hendrickson from resurrection the Demon Clan even if it is temporary, but the Great Holy Knight does not respond to Howzer's request. As Howzer spoke, Gowther seemingly regained consciousness and used Searchlight on Howzer and says his words hold no deception. Howzer is alarmed due to Gowther's sudden recovery and believes that he was stabbed through the chest. Diane thanks Howzer for helping them, but Gowther mentions that Howzer isn't doing it for them, but for Diane which Howzer denied while blushing. When Dreyfus accepts the idea of the truce, Howzer is shown happy for Dreyfus and goes off with the others to save Elizabeth.

While on their way to save Elizabeth, Howzer and the Sins feels a large amount of power exerted with very strong force in a nearby battle. After they are joined by Meliodas, Gilthunder, and Margaret, Meliodas explains Gilthunder's cruel personality and why he had to be ruthless in the past. Howzer feels disappointed in himself as he did not know what was going on with his friend. Despite Howzer's guilt, Gilthunder does not blame his friend. Howzer finds out that Arthur Pendragon, the new king of Camelot, is now on their side. Arthur explains that he does not know his own ability and as such, he attempted to find out by fighting Hendrickson, at which Howzer comments that he is an idiot. Howzer and the others are suddenly teleported to a forest by Vivian but are sent back to Liones by a mysterious cloaked figure who is soon revealed to be Merlin, the Boar's Sin of Gluttony. After Merlin frees Elizabeth and Bartra, everyone start interrogating Dreyfus for his crime of murdering Zaratras and framing the Sins which Howzer has a hard time to accept until Dreyfus admits it was true, much to Howzer shock.

Another of the knights asks what to do about Derieri, Howzer is unsettled to see how she and Elizabeth talk.

When the Archangels are defeated and the Sins can not harm him, Elizabeth decides to surrender to him to avoid more deaths, being taken to heaven by him.

While Howzer tries to help an injured Gila, the knights say they must go to rescue Elizabeth, but Howzer tells them they can not follow them through the sky. When King decides to pursue them on his own, Howzer asks forgiveness for only being able to depend on him with the Archangels defeated. However, Sariel and Tarmiel manage to recover from their wounds, leaving Howzer in shock to see Sariel become a beautiful woman. Sariel goes on to reveal that the power of a high-ranking Goddess can cause transformations in their vessel, such as the accelerated growth of Solaseed's body. Howzer asks why Tarmiel has not been transformed, which he explains is because Arbus was already dead when he  was turned in his vessel.

Upon hearing the story of how Solaseed and Arbus became the vessels of the Arncaneles, Howzer asks if the bodies really will be right with them inside. Sariel reveals to him that if he and Ludociel continue using their Graces, the bodies of Solaseed and Margaret will end up being destroyed, alarming Howzer. Sariel and tarmiel then decide to abandon their vessels, having partially reconstructed their original bodies. Howzer asks them how they intend to face such a powerful enemy, hearing the Archangels kill him in order to end the war.

Howzer decides to continue the road to Camelot, asking King, Sariel and Tarmiel to beat Estarossa and rescue Elizabeth.

Later, when a shower of light and dark rays begins to fall in the direction Elizabeth was taken, Howzer wonders what will happen. He tries to get Diane not to worry about King, only to discover that Diane has already left.
