Majin Bone

In modern-day Japan, a phenomenon is occurring, dismissed as irregular land subsidence and unusual weather patterns. Ryuujin Shougo is your average high school student, heading to school as always with his childhood friend Saho. Three young men are tailing him -- "Is he really Dragon Bone? Humanity's last hope?"

Having transformed into Dragon Bone, Ryuujin Shougo is warped into a strange alternate dimension, where he fights the mysterious enemy Dark Bone. Dark Bone gives Dragon a hard fight, and drives him to the brink of destruction. Just then, three mysterious silhouettes appear behind Dragon.

Shougo equips his Bone with the three young men Antonio, Luke, and Tyrone. By demonstrating that he can equip Dragon Bone with his own will, Shougo has proven himself a chosen warrior. Shougo doesn't understand what's going on, but Luke explains to him that Dark Bone is trying to steal the Bones of Earth, and if all the Bones are stolen, there is a chance that the Earth could be destroyed.

Dark Bone has appeared, but Shougo can't transform into Dragon. The Bone has the will to fight, but Shougo is unconsciously rejecting the fight. Therefore, he can't equip his Bone. Shougo stews over the questions of why he must fight, and why he was chosen for his Bone.

The fourth Bone adept, Gilbert, arrives at an airport in Japan. Shougo and the others go to meet him, and learn that he is a thirteen year old boy. But he is also the most severe out of all of them. He's looked through Shougo's file and immediately declares that he took too long to adapt to his Bone.

Gilbert equips Leo Bone and fights Dark Bone for the first time, but Dark Bone forms a line and summons a Majin. Their leader, Dark Horse, has such powerful kicks that Leo can't hope to match him. Shougo, shaken by his first sight of a Majin, begins to feel anxious over whether they could ever hope to beat them.

Dark Bone summons a Majin once again, but Dragon summons a Majin to oppose it. The Majin's power fills Dragon, who gets a Bone Crush on one of the Dark Bones. The Dark Bone's true face is revealed... and it looks almost human! The Dark Bones retreat, and the fist Dragon used to land the blow fossilizes. After unequipping, Shougo realizes that the change extends to the Dragon Card, too: Dragon...

At the Bone Research Facility, Higashio informs Shougo of a shocking truth: Dark Bone are extraterrestrial life forms, and they're invading Earth to get at Dragon Bone. Shougo decides that if it weren't for Dragon Bone, the enemy wouldn't be there putting the people around him in danger.

Wolf and Tiger enter the laboratory to steal Dragon Bone. The Bone Fighters other than Shougo equip and enter the Revelation Cocoon to fight Tiger and Wolf. Shougo had decided not to equip Dragon Bone anymore, but when he realizes how badly Shark and the others are struggling against Wolf and Tiger, he goes back on that decision.

Shougo and the others return from the laboratory and get back totheir everyday lives. Saho notices that Shougo has changed somehow. The others told her that they were helping out at Luke's family farm. Did the farm work change Shougo? Saho finds it all too strange. Meanwhile, Gilbert can't forgive Shougo for getting back to daily life so lightly.

When Dark Horse appears, Gilbert is secretly relieved to see that it wasn't the powerful Wolf and Tiger. Unable to forgive himself for that half-hearted way of thinking, he throws himself into training. Dark Horse, sent into a panic by Dragon's overwhelming strength, makes preparations to challenge Dragon to a final battle.

The aftermath of the battle leaves the city deeply scarred. Shougo is disturbed by the reports of the incident as a natural disaster. To keep the real situation from reaching the public, the laboratory is controlling the release of information. But they still lack conclusive data about the giant Majin hand that crushed Dark Horse in battle.

Shougo has been swallowed up by the berserk Dragon Bone. Leonard comes to Japan to bring him to the safety of a hospital. The Bone equip has released but Shougo remains unconscious. Luke and the other Bone Fighters are worried. So is Saho. Kengo remains unshaken, though, and calmly sees to Luke, Saho, and the others. While Shougo lies in his hospital bed, his consciousness converses with Drag...

Shougo notices something off in Luke's demeanor. Antonio and the others are worried that he might be conflicted over nearly going berserk in the last battle. They are told that is the son of the head of the Bone Research Organization, and that Luke bears the weight of expectation as a Bone Adept. Meanwhile, Gustos and Morse, in order to get revenge on Shougo and the others for beating Liebert...

Luke became an Adept when he was a child, almost as if guided by destiny. Later, when his father was promoted to head of the Bone Research Organization, the two parted ways. Luke had to live his destiny as a Bone Fighter all alone. As a result, Luke will not hesitate to sacrifice himself to protect Dragon. Shougo, Antonio, and the others are worried about Luke's reckless course of action.

Luke's descent of the Majin of Water has Gilbert feeling restless. When he looks back over their battles, he can't help but notice how far he's trailed behind his allies after his bragging about being the "Ace." Lost in these thoughts, Gilbert goes about his morning sparring in the park, where he runs into Saho.

Leo drives Tiger and Wolf away with the incredible power unleashed by his Bone. For some reason, that power ends up fossilizing Leo Bone. Gilbert claims that when the power was unleashed, he heard the Bone's "voice," and Tyrone shows a reaction to that word. Long ago, Tyrone's brothers and sisters heard Rhino Bone's "voice" and carried its card to Tyrone...

During morning training at the dojo, Shougo watches in surprise as Antonio and Luke have a capoeira vs. aikido battle that indicates just how well they must know each other. After training, Antonio heads out for his part time job as usual. Shougo and Luke go to watch him at work, which turns out to be a juggling performance in town.

As Dragon, Shark, and Jaguar fight against Wolf and Tiger; Dark Wyvern, Dark Eagle, and Dark Alligator appear. Gilbert and Tyrone note their appearance, and run to the vicinity of the Revelation Cocoon. But since their Bones are fossilized, they cannot enter the cocoon or help in any way.

Despite the oppressive power of the Iron Bone, Dark Wyvern, Leo also becomes an Iron Bone and manages to drive it off.. but it seems unlikely that they'll be able to drive off Dark Wyvern should it appear again. In order to discover how the other Bones can become Iron Bones, Shougo and the team head to the Bone Laboratory in Melbourne.

The examination of Leo Bone and Gilbert continues at the lab, as the scientists try to unlock the secrets of the Iron Bone. Meanwhile, Shougo, Antonio, and Tyrone are at a cafe in Melbourne. It seems that someone inside the laboratory took down the guard system to allow Dark Alligator to break in.

Dark Wyvern's Adept, Klude, appears in the city of Melbourne. He asks Dragon Bone's Adept, Shougo, why Dragon Bone sides with the Earth. But Shougo doesn't know. Despite being an Adept, Shougo doesn't know anything about the situation, so Klude explains to him how the universe was born, and why the Primordial Majin wants to destroy Earth.

Saho is complaining to Shougo about how unfulfilling her summer has been, when suddenly her father, Katsuya, returns home from a long business trip. Meanwhile on Nepos, Klude meets with Stolz, who is keeping an eye on the young Eques while feeling concern for his daughter, Liebert.

Liebert is troubled. Shougo and the Bone Fighters of Earth, have opposed her time after time. She can't reconcile their defiance against the Primordial Majin with her own beliefs which, as a Neposian, require her to honor and serve the Majin. When she hears that they have nevertheless somehow achieved Iron Bone status, she goes to ask Klude directly.
