After the battle between Cain Barzad and King ends, Howzer finds Veronica at the place Griamore landed after being defeated and sent flying. 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. 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. Though losing badly, Taizoo refuses to give up due to his ego. He is greatly shocked when Matrona manages to defeat Griamore despite his ability, calling the mysterious lady a monster.

Howzer observes Griamore and Matrona's first battle, speaking of Griamore's ability's power when the Holy Knight activates it. 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. In the main tournament, his first fight is assigned to be with Taizoo. During the preliminaries, Howzer is shown to be flinging a fighter, and after they end, is seen among the eight people who have advanced. He is delighted that he is finally able to enter the tournament, and to be not restricted by work. Howzer is then seen to have joined Vaizel's Fight Festival when he stops Taizoo and Meliodas's skirmish.

Though their origins are mysterious, Howzer, optimistic as usual, only considers their benefits, and soon leaves, citing busywork. This greatly shocks Howzer, who then also begins a conversation on the "New Generation" of Holy Knights.

Dreyfus replies that the Sins are a grave threat, and proceeds to inform the two of Meliodas having destroyed Danafor. 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. 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.

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.
