Saint Seiya: Legend of Crimson Youth (聖闘士星矢 真紅の少年伝説/Saint Seiya: Legend of Crimson Youth) is the third film in the Saint Seiya movie series, released on July 23, 1988. The story revolves around the Saint Seiya warriors and their battle against the Norse sun god Abel (フォェボス アベル) and his subordinates, the Corona Saints.

The story begins with the sun god Abel inviting his sister, Saori Kido (the reincarnation of Athena), to return to the Sanctuary's forbidden area, the Corona Temple (Dignity Hill), with the intention of triggering a flood to destroy all of humanity and reestablish a golden age of the gods. Saori tries to persuade Abel to change his mind, but he insists on his plan. He officially declares war on the Saints and even resurrects five deceased Gold Saints: Scorpio, Gemini, Aquarius, Capricorn, and Pisces. Saori decides to assassinate Abel but is killed instead, her soul falling into the underworld. This act causes dissatisfaction among Athena's loyalists, Camus and Shura, who plan to attack Abel but are defeated by three Corona Saints.

When Shiryu faces Scorpio's Deathmask again and is sent to the underworld, he sees Saori and ultimately unleashes his Cosmo, using the Lushan Rising Dragon to defeat Deathmask. Shun encounters Aphrodite and is wounded by his white roses, but Ikki arrives and quickly defeats Aphrodite. Next, Saga defeats Seiya and informs him that Saori is near the end of the Underworld Road (Yomotsu Hirasaka). Falling into it would prevent her soul from being revived. Meanwhile, Hyoga discovers that Camus is dead and, in his anger, uses the Aurora Execution to defeat Coma Berenice. Seiya, empowered by Saga's guidance, defeats him. Severely wounded, Saga performs the Galaxian Explosion, taking Lynx Jaow down with him.

When Seiya and his companions finally reach the Corona Temple and are defeated, Seiya, Shiryu, and Hyoga don the Gold Cloths of Sagittarius, Libra, and Aquarius, respectively, quickly defeating Carina Atlas. However, they are attacked by Abel. Seiya, using the power of his Cosmo, successfully rescues Saori from the underworld and then unleashes a Cosmo beyond the gods, using his arrow to defeat Abel.

Saint Seiya: Legend of Crimson Youth is beloved for its intense and exciting battle scenes and its deep themes of love, peace, and the future of humanity. This movie holds an important place in the Saint Seiya series and is highly regarded by fans.
