Dragon Shiryu (龍星座の紫龍, Doragon no Shiryū?, shiryū meaning "violet dragon") is considered the most matured of the five heroes, and thus the wisest. As the Bronze Saint of the Dragon constellation, Shiryu dons the emerald Dragon Bronze Cloth, a jewel among the Cloths due to its legendary defense properties. Out of all five main characters, Shiryu is known as the calmest and most collected. His sheer physical strength is the greatest of the Bronze Saints, with perhaps the exception of Phoenix Ikki. This is reflected in his ability to have won numerous battles without his Dragon Cloth. Shiryu trained at the Five Old Peaks in China to obtain the Bronze Cloth of the Dragon constellation, and his mentor was none other than senior Gold Saint, Libra Dohko. During his training in Rozan, Shiryu awoke his Cosmo and learned many fighting styles and fundamental wisdom for life, from Libra Dohko. During the Sanctuary Arc, Shiryu awakes the 7th sense in his fight against Cancer Deathmask and later he awoke the 8th sense during the Hades Arc.
His signature technique is Rozan Rising Dragon Force (廬山昇龍覇, Rozanshōryūha?). It is a blow that usually knocks the opponent soaring into the air as an image of a dragon devours him. The power of the Rozan Rising Dragon Force can vary from capable to explosively powerful, depending on Shiryu's Cosmo level at the time of execution. Unlike the favorite techniques of the other Bronze Saints, however, Shiryu's Rozan Rising Dragon Force does have one weakness -- while performing the move, his heart will be left open for a millisecond. Only three people in the series have noted this: his master, Libra Dohko, Bronze Saint Pegasus Seiya and Gold Saint Capricorn Shura.
Other attacks in his arsenal include Rozan Dragon Flight (廬山龍飛翔, Rozanryūhishō?), a straight-to-the-point, jumping attack where Shiryu charges through his opponents with a single fist and Dragon's Kick (ドラゴンの蹴り, Doragon no Keri?), that Shiryu has, to date, used only once, against Cancer Deathmask, in vol. 8 of the manga, and therefore, in episode 39 of the anime adaptation. Shiryu leapt high into the air and dived toward his opponent with a sharp kick to the head. Also, although he has only used it once to date, among his defensive techniques, Shiryu counts the fabled Catch of a real sword's blade (真剣白刃取り, Shinken Shiraha Dori?); the traditional technique used in Japanese Kenjutsu to repel an opponent's sword when unarmed, Shiryu used it to stop Capricorn Shura's attacks as his fists and legs were similar to a razor-sharp blade.
During the Hades Arc Shiryu learns the Rozan One Hundred Dragons Force (廬山百龍覇, Rozanhyakuryūha?). Shiryu learned it from watching his master's battle (although being blind in that moment). It is a technique that appears to be a 100x of the Rozan Rising Dragon Force or the Rozan Dragon Flight -- Shiryu's Cosmo erupts at its maximum, and he ploughs through the enemy with both arms and palms extended. 100 dragons march in the sky as the enemies are destroyed by this energy-based offensive attack.
The final move that Shiryu uses when all else fails is Rozan Enraged Dragon Force (廬山亢龍覇, Rozankōryūha?). It is a kamikaze technique similar to Seiya's "Pegasus Rolling Crush," except while Seiya normally intends to send both himself and his opponent back to the ground, Shiryu will continue to soar into the air and eventually into space -- killing both himself and his enemy. The Rozan Enraged Dragon Force is something that Dohko had strongly discouraged Shiryu from using, even going as far as putting a ban on its use.
After defeating Capricorn Shura, Shiryu is entrusted with the Gold Saint's legendary technique Excalibur (聖剣, ekusukaribā?). It is not a physical sword, but a deadly Cosmo precision focused on Shiryu's right arm. Although Shiryu's version of the sword was not as defined as Shura's (Shiryu's Excalibur lies only in his right arm, while Shura's can be unleashed from any of his limbs), the Dragon later refined it enough to rival Shura's and used it to cut the unbreakable golden spear of Chrysaor Krishna, the powerful Mariner General during the Poseidon Chapter.
