The 2009 anime Saint Seiya: The Lost Canvas opens on three orphans in Italy. Tenma, Alone and Sasha grow up protecting each other, then get separated. They make a pact to meet again. They do meet again. By then Tenma is the Pegasus Saint, Alone is the god Hades, and Sasha is Athena. The show runs 26 episodes across one season, first airing June 24, 2009, and closing July 20, 2011. It scores 8.3 out of 10.
That premise is the whole engine. Saint Seiya: The Lost Canvas takes the oldest trick in the franchise — friendship turned to war — and gives it a specific, bitter shape. These are not strangers who become enemies. They are children who promised each other something and then found out what the world had planned instead.

Tenma, Alone and Sasha
The original Saint Seiya, written and drawn by Masami Kurumada, sent five Bronze Saints through the Sanctuary and up to the gods. The Lost Canvas goes back 250 years earlier, to the previous Holy War, in the 18th century. The manga was written and drawn by Shiori Teshirogi, published by Akita Shoten in Weekly Shōnen Champion from August 24, 2006, and it ran 223 chapters before ending April 6, 2011, collected in 25 volumes.
The setup is spare. Sasha is recognized as Athena by Sagittarius Sisyphos, sent to the Sanctuary first. Tenma follows shortly after. His Cosmos — the Saints’ energy — awakens, and Libra Dohko spots the talent and sends him to become a Bronze Saint. Alone stays behind, and the god Hypnos and his follower Pandora convince him that death means salvation. He becomes Hades.
The show does not waste time on the reunion. It knows the audience already feels the weight of the pact. What it does instead is show the cost in institutions: a Sanctuary, a Pope, an army of 108 Specters, a war with rules older than any of the three friends.
The 108 Specters and the Rosary
Alone gathers Hades’ soldiers, the 108 Specters, and starts the war. The Saints answer. Piscis Albafica holds the Sanctuary and a nearby town against Alone’s forces and dies doing it. Virgo Asmita sacrifices his life to make a rosary that seals the Specters’ souls, which stops Alone from bringing them back.
That rosary is the best structural idea in the series. It turns the usual Saint Seiya problem — enemies who keep returning — into a finite count. Every sealed soul is one the war can never spend again. The show gets a clock without ever showing one.
Then Alone starts the Lost Canvas itself: a vast painting of the earth, made in the sky. When it is finished, the whole world dies. The two gods are sealed by the former Pope Sage and his twin brother, Altar Hakurei. Alone invites the remaining Saints into the Demonic Temples inside the Lost Canvas.
Cast and the Sound of the War
The voice cast carries the three leads. Tetsuya Kakihara plays Pegasus Tenma. Hiro Shimono plays Alone and Hades. Aya Hirano plays Sasha and Athena. The doubling matters — Shimono and Hirano each have to hold two people in one throat, and the show leans on that.
Around them: Atsushi Abe as Unicorn Yato, Sanae Kobayashi as Yuzuriha, Shin-ichiro Miki as Aries Shion, Kenta Miyake as Libra Dohko, and Nana Mizuki as Pandora. Mizuki’s Pandora is the one who talks Alone into his godhood, and the performance has to sell a persuasion, not a possession.
The genres are Animation, Action & Adventure, and Drama. That third one is doing real work here. The fights are the delivery system; the drama is the payload.

Dohko, Shion and the Cost of Cover
The back half of the war is a chain of sacrifices, and the show is honest about what each one buys. Tenma reaches Alone with Dohko’s help, and the two are beaten. Dohko stays behind to buy time so Aries Shion can teleport Tenma out.
That is the pattern: someone holds a door so someone else can keep moving. Sasha sends Scorpio Kardia and Aquarius Dégel to find an item that will power a flying ship to reach Alone. The mission exists so the story can get to its last room.
The show’s willingness to spend its own characters is what separates it from a toy commercial. Albafica dies. Asmita dies. Dohko stands his ground. None of it is reversible, and the rosary means even the enemy’s dead stay dead.
Where the Show Sags
The Lost Canvas is a prequel, and prequels carry a tax. The audience knows the Holy War ends with the Saints’ side surviving into the original series. That knowledge flattens some of the tension. The show’s answer is to make the cost personal rather than cosmic, and it mostly works, but the Demonic Temples stretch.
The middle run of episodes settles into a rhythm: new Specter, new Saint, new sacrifice. The rosary gives that rhythm a count, which helps. It does not fully solve it. Some fights exist to fill a slot, and the show’s 26-episode season has more slots than it has ideas for.
The other limit is scale. Alone’s Lost Canvas is a painting of the entire earth in the sky. That is a striking image. The show rarely makes you feel the size of it. The threat is stated more often than it is shown.
Why the 8.3 Holds
The score sits at 8.3 out of 10, from 673 votes on TMDB. That is a high mark for a spin-off of a decades-old franchise, and it is earned by the parts that are specific rather than the parts that are grand.
What The Lost Canvas gets right is the triangle. Tenma, Alone and Sasha are not symbols. They are three kids who made a promise and got handed roles they never asked for. The show’s best scenes are not the biggest ones. They are the ones where two of them are in the same room and one of them is already gone.
Here is the part worth watching:
- Tenma’s Cosmos awakening, and Dohko recognizing it
- Sasha recognized as Athena by Sisyphos, and sent away first
- Alone convinced by Hypnos and Pandora that death is salvation
- Albafica dying to protect the Sanctuary and a nearby town
- Asmita’s rosary, which seals the Specters’ souls for good
- Dohko holding the line so Shion can teleport Tenma out
That list is also the show’s argument. Every entry is someone choosing to spend themselves so the story can continue. The franchise has always been about that. The Lost Canvas just makes the bill visible.
Teshirogi and the Prequel Problem
The spin-off’s origin is worth noting. Teshirogi’s earlier work caught Kurumada’s attention, and he gave her permission to write a prequel while he was writing his own, Saint Seiya: Next Dimension. The two exchanged ideas. Teshirogi had come from shōjo manga and had to adapt her writing and art to a male readership. Two months after the main serialization ended, she started a spin-off from The Lost Canvas.
That background explains the show’s texture. It is a war story drawn by someone who cares about what people feel before they hit each other. The 18th-century setting, the 250-year gap, the 108 Specters, the 223 chapters — all of it is scaffolding around three orphans.
The verdict: Saint Seiya: The Lost Canvas is the best kind of prequel, one that earns its place by narrowing rather than expanding. It does not try to outdo the original’s scale. It picks three people, gives them a promise, and then makes them pay for it. The Demonic Temples drag, and the middle episodes repeat themselves. The ending still lands, because the show never forgets who is fighting.
