1. Awaken! Red Kakuzyu King!

Shout the Fiery, a treasure hunter well-versed in ancient scripts, spends his days deciphering ancient manuscripts, setting out on expeditions, and unearthing ancient artifacts. One day, while exploring an ancient ruin, Shout discovers the “Kakuzyu Awakener Omegahorn” and the “Egorgears” Though puzzled by the Omegahorn—which differs from the Kakuzyu Awakeners used by modern hunters—he tries setting the Egorgear into it, and a giant horned beast named Enkaku appears! Enkaku recognizes the qualities of a “King” in Shout’s ego (his unwavering resolve to follow his own path) and, calling himself “Captain Omegahorn,” demands that Shout fight alongside him…!?

2. Show Me! Captain's Qualifications!

Twin hunters—Ail the Bold and All the Upright—are asked for help in a certain town. It turns out the townspeople have been swindled out of their treasure by a con artist. To reclaim the treasure, Ail and All challenge the con artist to a Hunter Battle, but find themselves in a desperate, life-or-death situation. Just then, Shout and Enkaku rush to their aid... Meanwhile, the Ibaru Alliance, led by Ibaru of Despair, was heading toward the western territories to subdue a group of armed hunters running amok...

3. Savor It! The Furious Tag Battle!

Giriko the Wave-Slasher—who had been watching Shout and the others fight—challenged them to a Hunter Battle! However, the battle was interrupted by hunters from the Ibaru Alliance who suddenly appeared. Shout and Giriko were captured and taken to the “Egorgear Quarry”... At the mining site, many residents were being forced to mine under grueling conditions. Shout forms an impromptu tag team with Giriko, and they end up facing the Ibaru Alliance hunters in a 2-on-2 battle...!

5. Find It! Your Own Unique Ego!

Shout reunites with Ail and All, who ask him about a mysterious flying Kakuzyu called “Nazokaku.” Nazokaku isn’t listed in the Kakuzyu Encyclopedia, and it seems even Enkaku doesn’t know about it. They all decide to search for Nazokaku, but All alone looks somewhat downcast… Eventually, the group enters a cave where Enkaku had picked up a mysterious scent. There, they encounter hunters from the Ibaru Alliance, and Shout and the others are attacked and left unable to move. In the midst of this dire crisis, All—the only one still unharmed—takes on the hunters in battle, but…!?
