Saint Seiya: Legend of Justice

Licensed anime idles usually bet everything on the face on the box, and Saint Seiya: Legend of Justice is no exception. Hoolai Game launched this vertical-screen idle RPG in 2022 with the full blessing of Masami Kurumada’s estate: Pegasus Seiya, Phoenix Ikki, Virgo Shaka and Gemini Saga all report for duty, and the Poseidon chapter of the original manga is retold with strict supervision. Under the armor sits a familiar gacha auto-battler, one that leans on an elemental counter wheel instead of raw reflexes. Whether that wheel is enough depends entirely on how much the Saints mean to you.

What the loop feels like

Your first scene is formation day. Six Knights line up against a Marina general, and the pre-battle screen is where the real fight happens: you check the elemental wheel, swap a Water Knight into the front rank because the enemy vanguard burns hot, and set your highest-rarity carry where her ultimate will land when it matters. The battle itself runs itself, with skills firing on rhythm and your one job being to trigger ultimates at the critical moment rather than dodge anything by hand.

The second scene is the next morning. You collect the overnight idle payout, clear a short stack of daily quests, dump the gold coins, knight experience and magic stones into level breakthroughs, and feed duplicate fragments into your SS-rank core so its stat ceiling climbs one more notch. Then you log off and let the accumulation do the work. That’s Saint Seiya: Legend of Justice.

How it actually works

The Elemental Affinity System is the spine: fire beats wind, wind beats water, water beats fire, while light and dark counter each other and sit neutral to the main triad. Knights are sorted into class, expertise and rarity ranks from C up to SS, dictating whether they tank, deal damage or support. Progression stacks four systems on top: level breakthroughs gated by gold coins, knight experience and magic stones; gear dropped from major quests that must match a knight’s expertise; rarity evolution, where duplicate fragments and lower-tier fodder push SS and S characters past their stat ceilings; and late-game artifact salons plus Arai Yashiki card sets that stack passive statistics. The veteran doctrine follows directly: pour resources into a handful of top-rarity carries, keep a diversified element bench so the counter wheel never locks you out of a stage, and let idle and daily rewards carry you through bottlenecks without spending.

The campaign retells the Poseidon arc beat for beat, so the story mode doubles as a nostalgia tour: descend with the Knights of Athena, challenge Sea Dragon Canon, Siren Sorento and Kraken Isaac, and rescue the Goddess. New-player events hand out a five-star Gold Knight on day two and a six-star Leo Aioria on day seven, which sets the spending rhythm early.

Where it stumbles

The late game hits hard paywalls that tilt high-level PvP and PvE toward paying players, and the semi-automatic combat fades into background noise once raw levels and star tiers decide most encounters. Outside the fanbase the presentation reads threadbare: the storytelling assumes you already know who these characters are, and anyone who cannot tell Shaka from Saga will find little to hold onto. Gacha fatigue is the constant undertow, the same one dragging every licensed idle of this vintage.

Playing it today

It is free on the App Store with in-app purchases, exclusive to iOS from Hoolai Game, and still running past its fourth anniversary with seasonal events. If you want the same auto-battle rhythm without the license, Almost a Hero and Soda Dungeon cover the genre’s friendlier side.

The verdict

Saint Seiya: Legend of Justice is exactly what it looks like: a competent idle RPG chassis wearing beloved armor, with the nostalgia doing most of the heavy lifting. Die-hard Saints get their short daily bursts of Sanctuary; everyone else should expect a paywall somewhere past the horizon and a cast they were never introduced to.
