Warrior of the Rabbit, Usagi, is a Necromantist, who makes other warriors into his "friends." Warrior of the Ox, Ushii, and Warrior of the Tiger, Tora, end up facing off against two of these "friends," the Tatsumi Brothers. As they prepare for the battle, Tora, who holds a grudge against Ushii, thinks back to her days spent searching for righteousness.

The Warrior of the Dragon, elder of the Tatsumi Brothers, is a superficially arrogant but cool-headed warrior who acts as commander in his collaborations with his brother. Using his "Heaven's Holding" ability to remain in the air, he watches over Snake, now a "Walking Dead," waiting for his own chance to join in the battle. While he does so, he thinks back on a trial that they became subject to as a result of their actions on a different battlefield.

The Warrior of the Snake, younger of the Tatsumi Brothers, is a dangerous individual who would have become a pyromaniac if he hadn't become a warrior. On their way to the Juni Taisen, he remembers the day his brother saved his life, just after learning that only one of them would survive the ordeal. Then, as they arrive at the starting venue, the warrior Usagi approaches them, asking them to become his friends...

Warrior of the Horse, Uuma, has trained his physical body to its limits to acquire the ultimate defensive technique, "Stirrup." But his confidence in that ability faltered during his meeting with the Warrior of the Ox, which ended poorly for him. Uuma barricades himself in a bank fault, thinking he can win if he waits out the time limit... but an intruder casts doubt on that goal.

Warrior of the Monkey, Sharyu, is a powerful fighter with the ability to manipulate the three states of matter with ease. Rather than using her power to fight, though, she travels the world as a negotiator, seeking to bring about ceasefires and peace agreements. She seeks peace at the Juni Taisen, as well. But when her lone ally, Nezumi, the Warrior of the Rat, asks her if people are really worth saving, she is reminded of her experiences on the battlefield.

Warrior of the Chicken, Niwatori, may not have the power of the other warriors, but she does have the ability, "Eye of the Cormorant," that lets her see what the birds see. She has survived through battlefield after battlefield thanks to this, as well as her ability to betray others without any pangs of conscience. However, her philosophy is shaken when she meets the Monkey Warrior, Sharyu, for the first time.

Warrior of the Dog, Dotsuku, is known for his powerful bite, "Mad Dog's Vise." However, he has a secret skill: the ability to create and secrete a variety of poisons from his body. This provides Dotsuku an advantage in a contest where all the participants have been poisoned to enforce a time limit. His plan is to let the other warriors kill each other, and wait while they thin out their own numbers... but his plan is interrupted by a certain under-the-radar warrior.

Nezumi, Warrior of the Rat, is an ordinary high school student in his normal life. He used his ability, Hundred Paths of Nezumi-san, to become the Taisen's lone survivor, and in the process learned the wishes of the battle's other participants. When Duodecuple reappears and prompts him for his answer, Nezumi does as Ox taught him, and offers the one answer that is right for him.

The Warrior of the Ox, Ushii, is seen by other fighters as "incomprehensibly powerful." The genius combatant uses his systematic killing style to see his own righteousness fulfilled on battlefields, and to slaughter any enemy he comes across. But once, on one battlefield, this same "Genius of Slaughter" saved a girl...

The Warrior of the Tiger, Tora, born to a family of martial artists, engaged in battle with a burning sense of duty. Not long after, though, the grim realities of war discouraged her and drove her to drink. In the depths of her despair, she met a warrior who seemed to brim with righteousness. She joined the Juni Taisen in order to meet that warrior again, and now, it seems her dream of a duel with him may be granted...

The Juni Taisen takes place once every twelve years. The participating warriors must kill each other until only one remains; this winner will have one wish granted. Warrior of the Boar, Inonoshishi, is the daughter of the last Taisen's winner. She sabotaged and destroyed her little sister in order to take her place at the Taisen, because her pride as eldest daughter could not withstand the thought of being displaced. She uses her skill "Non-Reload" and swears to win elegantly, but she ends up fighting her first enemy in an unexpected way.
