Ryuujin Sword

Ryuujin Sword (龍): Created by the orb of The Dragon, it contains all of the powers of the six other orbs, from Water to Ice. Whenever he uses it, the Raijin-ken changes its shape turning into the Ryūjin-ken. This also happened when he used the orb on Onimaru's Fūjin-ken when the Raijin-ken was swallowed by Kaguya-hime. The orb has 3 abilities: One, Yaiba can now fly while holding the sword. Two, it can create a powerful energy shield that can block projectiles. And three, he can summon the Dragon God by activating all of the orbs, including the Dragon Orb as well to unveil its ultimate power.

The power of Ryujin is based on the Legendary Spheres, and according to Ryujin himself, the powers were increased 10-fold, thus offsetting some drawbacks and/or further enhances its capabilities.


 * 水 Sphere of the God of Water. It can throw jets of water and dominate the seas (divide it into half and allowed Yaiba's group to cross). It was located in Lake Biwa and the color of the orb is blue. Yaiba barely uses it offensively on its own. As part of the Ryujin's orb power, its power increased and allowed Yaiba to control more powerful water waves, and he often uses it as part of his attack combo with the Ice Orb.
 * 金 Sphere of the Metamorphoses (Gold). It allows its bearer to become the person, creature or object that he wants. When first used, it resulted with rather a transformation battle with Amakusa Shirou. It was located in Shikoku and the color of the orb is gold. The orb was barely used in battle and its name is always being made fun of by Yaiba mostly (much to Sayaka's chagrin because it was often referred as "racoon's balls"). As part of the Ryujin's orb power, its ability was improved in such that, Yaiba was still capable of using the other powers of the orbs (e.g. fire orb), while still in a transformed state. This was only used once when Yaiba has to disguise as Sayaka, in order to hide her from Gekko.
 * 火 Red Dragon's Sphere (Fire Orb). It has the ability to launch fire projectiles and envelop its user in a flame aura, in addition to making its carrier immune to heat. It has became Yaiba's main orb of choice offensively, since he lost the Raijin Orb to Onimaru, and Musashi even noted that its power is comparable to it. Although powerful, Yaiba was not available to control it easily at first, and even burned Shōnosuke because of his fire aura. It was located in Mount Aso, Kyushu and the color of the orb is red. As part of the Ryujin's orb power, its destructive flame powers increased drastically, capable of destroying mountains with a single fireball or fire-blast. Also, Yaiba was able to control it fully and does not even have to envelop himself with a fire aura all the time.
 * 大 Sphere of the Increase (Big). It allows the user to increase their size, temporarily converting it into a giant, and to some extent control how big one could get. The drawback however is that the user will get too exhausted after its use, and requires the orb to recharge before being used again. Yaiba attempted to use it in his next battle against Goemon Ishikawa, but it backfired and only increased the size of his head. It was located in the Buddha statue of Nara and the color of the orb is dark blue. As part of the Ryujin's orb power, the drawback was completely removed, allowing Yaiba to use it anytime and fully control his stature. Also, he was still capable of using the other powers of the orb, even in his giant state.
 * 闇 Sphere of Darkness. It can swallow any person or its own user, particularly with dreams and ambition, and send them to the World of Darkness. Yaiba was swallowed by the orb on his first attempt to use it, along with Jubei, who attempted to save him. After their adventures inside the orb, Yaiba and Jubei managed to escape from it just in time to save Sayaka and their friends from a rampaging Benkei Musashibo. Yaiba used it for a second time in order to defeat and absorb Basho Matsuo in it. It was located in Niigata spheres shop and the color of the orb is purple. As part of the Ryujin's orb power, it was the only one Yaiba did not use in battle due to its dangerous nature. It could be safely assumed that its drawback of absorbing its own user was removed, thus allowing Yaiba to absorb anything on it at will, but it was never shown in the series. The only time that its Kanji appeared in the orb was the time when Yaiba activated all the orb powers to defeat Kaguya.
 * 氷 Ice sphere. It has the ability to create blocks or waves of ice and freeze water or anything. Yaiba even mistaken it as another Water Orb, in which Sayaka corrects him immediately. The color of the orb is light blue and was found by Benkei Musashibo in Hokkaido, in which Musashi tricks him to obtain it. As part of the Ryujin's orb power, its ice powers increased, and is often used by Yaiba in conjunction with the water orb power.
 * 当 Sphere of the Enlightenment. It is a talking pink sphere, which knows where all the other spheres are and how to reach them. It was located in Tōhoku and Yaiba's group used the six other orbs in order to locate it from the hundred thousands of replicas that Basho Matsuo revealed them. After Basho was defeated, the group was somewhat dismayed that they found it last, and realized that it was still not the Dragon Orb. Seeing them possessing the six other orbs, it instructed them to go to Mt. Fuji to locate the Dragon Orb and undergo a series of trials to possess it. It was the only one that was not part of the Ryujin Orb's powers. The reason for this was unknown.
 * 龍 Sphere of the Dragon God. It gives its user the ability to fly, create shield of energy, a dragon avatar and a powerful energy blast to destroy the earth in full power. It also contains the powers of the six orbs from water to ice, and as stated by Ryujin himself, those powers were increased drastically. It was located in Crater of Mount Fuji and the color of the orb is lavender and bright green when it was activated. Yaiba took possession of the orb after passing all of Ryujin's trials and used it for the first time for his rematch against Onimaru. However, Yaiba was not fully aware that obtaining the Dragon Orb also awakens the sleeping Princess Kaguya in the moon.

Other Notes

While in Ryujin's possession, he was never shown (either in the manga or anime) to use any other of the orb's power, except for the dragon's power in his flashback battle against Kaguya. Also, it seems that he was capable of using the orb without having to put it in a sword, and it seems that he was not seen wielding the Ryujin Sword itself, except for a typical katana. After Kaguya's first defeat, it is unknown how Ryujin separated the orb's powers into seven other spheres, while still possessing the orb itself upon hiding it in Mt. Fuji.

After Yaiba defeats and "seals" Kaguya into the earth, Ryujin takes back the Dragon Orb and it vanished along with him.
