It is a spin-off based on the manga series Saint Seiya, which was created, written and illustrated by Japanese author Masami Kurumada.

The Lost Canvas was published by Akita Shoten in the Weekly Shōnen Champion magazine since August 24, 2006, concluding after 223 chapters on April 6, 2011, with twenty-five tankōbon released.

[2] In June 2009, TMS Entertainment started adapting the manga in original video animation format, producing 26 episodes, which followed the source material closely and occasionally expanded on it with Teshirogi herself writing these new scenes.

[3] While the two were close childhood friends in Italy alongside Alone's sister, Sasha, the trio separated when Sagittarius Sisyphos recognized her as Athena.

After testing Tenma's power, Virgo Asmita sacrifices his life to create a rosary that seals the Specters' souls and prevent Alone from reviving them.

After reviving, Tenma takes Asmita's rosary to the Sanctuary where he and Sasha have to deal with Alone who starts making the "Lost Canvas", a vast painting of the earth, in the sky, so that after he finishes it, the entire world will die.

The Bronze Saints led by Sagittarius Sisyphos and his nephew Leo Regulus make the ship but the former dies fighting the Specters opposing them.

Teshirogi liked the manga as well as the comments at the end of the volume by Masami Kurumada, as he she could really feel the passion the author put into his world.

[5] She particularly enjoyed the Sanctuary arc for Gemini Saga and Acquarius Camus' battles against Pegasus Seiya and Cygnus Hyoga but ended favoriting Libra Dohko.

A few years later, when the publisher Square Enix organized a competition called the game fantasy manga grand prize, she participated and was selected.

Additionally, the characters designs and Cloths were based on the second season from the Saint Seiya anime adaptation (known as Asgard), but she combined them with her own style.

Lost Canvas started as a story about Tenma and Alone's relationship but advices from her editor resulted in further writing the Holy War, especially the popular Gold Saints which shocked the audience.

Tenma's father concept of a man who is responsible for most of the Holy War conflicts was created as a major plot twist Teshirogi used to further surprise the readers.

Scorpio Kardia was noted to be highly popular by Teshirogi due to the dynamic she gave to his personality as well as the contrast she gives Sasha.

The latter was written to contrast Kurumada's take on Athena's reincarnation, Saori Kido, as both have different personalities as a result of being born and raised in different places.

[4] Although Kurumada gave Teshirogi freedom with what to write, Teshirogi had problems across the entire serialization with one of her first three editors; She cited demands of more pages per chapters and ideas to make battles more interesting she found difficult like a Buddha statue fighting Athena's when the narrative involved the Gold Saint Virgo Asmita or how the Bat Specter could defeat Taurus Aldebaran.

When she received comments that these three Lost Canvas Gold Saints are more interesting than the ones from the original series, she answered that she did not mean to give them any special treatment.

[9] When the Gaiden moved to a monthly serialization, Teshirogi believed that her way of writing stories improved due to the time she was given with each chapter but had problems with portraying bishonen archetypes like Albafica's design.

Once the series ended, Teshirogi felt a sense of emptiness and expressed a desire to explore Yuzuriha and Yato's characters more as well as that Tenma did not have too many appearances despite being the hero.

[4] The Saint Seiya: The Lost Canvas chapters were published by Akita Shoten in the Weekly Shōnen Champion magazine since August 24, 2006.

A short story comprised in 40 pages, or gaiden, titled Saint Seiya: The Lost Canvas - Meiō Shinwa– Yuzuriha Gaiden - Chizumi no Mon (聖闘士星矢 The Lost Canvas 冥王神話 ユズリハ外伝 血墨の紋) was published on October 16, 2009, in the issues 11 and 12 of Akita Shōten's Princess Gold comics magazine, which is oriented towards a female majority demographic.

The story is set in the same continuity of Lost Canvas and further explores the past and motivations of the character Yuzuriha, and her younger brother Tokusa, as well as her perspective of the events surrounding the resurrection of Hades.

[22] Currently, TMS confirmed it has no plans for resuming production of the OVA series, leaving a large portion of the original manga not adapted to animation.

[42] GamerFocus called Lost Canvas a remake rather than a prequel due to how Teshirogi used characters from the original Saint Seiya series and gave them their own unique traits.

While still finding Teshirogi's take simple, the way she wrote the main cast helps to make it entertaining, sometimes even more than Masami Kurumada's Saint Seiya.

The protagonist Pegasus Tenma was noted to be too similar to Seiya but more likable while the Gold Saints instead are nearly identical to the original which might bring mixed emotions to the readers.

[44] Zona Negativa praised Teshirogi's artwork especially for the character designs she provides to the cast to the point of surpassing the original manga, making it highly appealing to people who wanted to see more of the Gold Saints, especially Dohko and Shion.

[50] Although the attacks performed by the character was found unintentionally funny by UK Anime Network as a result of its names, the notable display of violence made the reviewer wonder whether the show should be aimed towards a young audience.

[52] When the OVAs started production, Teshirogi was sad that one scene where Dohko talks with Tenma and Alone from the original printed version was removed in the anime.

One of the main animators contacted Teshirogi about his ideas to design the character as more obese than Toei's take and end with a more realistic style.
