For millions of years, Wild looked for his younger brother, coming to face the Demon King on many occasions, but always being defeated.

Current arc
While touring the Purgatory, Wild finds Meliodas and Ban who claimed to be from another world. When these two discover it, they immediately attack him believing him an enemy. However, Wild evades all his attacks and threatens Meliodas from behind. When these two ask him if he is a servant of the Demon King, Wild says that he knows how to find him. After revealing and introducing themselves, Meliodas and Ban are surprised to see their similarity to Hawk. Understanding that Hawk is his little brother, Mild, who has been searching, Wild breaks into tears of joy.

In the face of the impending sandstorm, Wild takes Ban and Meliodas home and offers them wild boar broths. After telling them about how his brother had been kidnapped by the Demon King, he asks both of them to tell him about Hawk. After hearing them, Wild suffers a shock to know how he is, but affirms that he will love him no matter what.

When leaving in search of the Demon King, Wild tells them that he has already faced the Demon King 120,118 times, losing the fight 120,118 times. There, Meliodas stops to tell Ban and Wild about his youngest brothers, telling about his past relationship with Zeldris. However, when Wild asks about Estarossa, Meliodas realizes that he does not really remember anything about him. Right there, the Demon King appears in front of the trio. Despite his overwhelming presence, Wild rushes to face him without hesitation, defiantly saying that he will finally force his way through the Demon King with Ban and Meliodas aiding him, only to be effortlessly flicked aside with a single finger. Recovering, Wild warns Meliodas and Ban upon seeing the Demon King slashing his sword at them. Wild later attempts to drill the Demon King, only to be effortlessly stopped and held between the King's fingers before being thrown away, with the Demon King saying that Wild never learns.

While sixty years pass in Purgatory, the trio still battles the Demon King, being defetead every single time they charge at him. When they were thrown away, Ban discovers that his powers could also "heal", as Wild's wounds have been "healed" by him, with this they also discovered how to get around with Demon King's power, The Ruler, and they charge at him once again. Despite the fact that Ban manages to hurt the overwhelming King, he still manages to revert the effect by switching off his power. Meliodas then tries to battle the Demon King himself, as the gate to the real world is revealed. Ban refuses to go, saying that he can not leave the Captain behind but Wild decides to use Wild Full Throtle, ultimately leading to his death, as this technique is considered by him his "Trump card", consuming all his life force to increase his power. With this technique, he was able to hold off the Demon King, giving Ban and Meliodas a chance to escape. In his final moments, he regrets that he could not see his little brother again, but is thankful knowing that he is alive and well, and considers that two good friends are better than an older brother about which he does not even know he exists.
