An action/adventure game for the Sega Genesis, also known as ''Soleil'' in PAL regions and ''Ragnacenty'' in Japan. It was published by Creator/{{Atlus}}.

Gameplay and visuals are similar to those in ''VideoGame/TheLegendOfZeldaALinkToThePast'' or the ''VideoGame/SoulBlazer'' series, with a few exceptions. Instead of collecting items, you have animals join your party. Two animals may be equipped at a time. Certain animals may be equipped with certain other animals to produce a unique or upgraded effect.

The game starts with your character on the birthday where he receives his first sword and becomes a man. He inherits the old sword of his father, a great swordfighter and hero. After learning to throw it, you venture out into the world to fight monsters and have a good ol' time. Except that not all is as it seems.

Essentially a large and fairly well done parable for environmentalist and expansionist issues as well as the morality of killing those who are different and strange.
!!''Crusader of Centy'' provides examples of the following tropes:
* AmplifierArtifact - The Moa Bird
* AncestralWeapon: Your father's rusty sword.
* AndroclesLion - Many of your recruited animals must be saved first.
* AnimalTalk - To the point that when you first receive the ability, you can no longer speak to humans. You get better though.
* [[BornInTheWrongCentury Born In The Wrong Timeline]]- The imprisoned adventurer in the epilogue.
* BrokenAesop: After spending the entire game [[{{Anvilicious}} beating it into the players head]] that the monsters are people too, deserve equal rights, and actually could coexist with Humans if the Humans got rid of their racism, [[spoiler:the ending does a complete 180 and has the hero banish all the monsters to the "underworld" where they originated from, because apparently monsters ''aren't'' people after all and could never coexist with Humans...]]
* TheCameo - SonicTheHedgehog
* CirclingBirdies - The Big Bad Wolf's attack consists of hitting himself on the head then using the stars to damage you.
* ConvectionSchmonvection: A stage is set around and inside of an active, near erupting volcano. Falling into the lava only removes 1 apple (life point).
* CrowningMusicofAwesome: [[ Battle 3/Leviathan]]
* DisappearedDad: Your father ain't around much. Don't despair. You have your best friend Johnny the dog and you get his sword.
** You get to see him again in Heaven. He doesn't have a name, but he's [[SoProudOfYou stereotypically dad-like]] and refills your health. It couldn't be anyone else.
** Your father [[spoiler:eventually reappears in the epilogue, alive and well in your family's house. Because the monsters never appeared in this world, your father never got killed by them either.]]
* FacelessEye
* FloatingPlatforms: Many many many floating platforms. Half the floor in some stages is such. Standing on the floor too long will make it collapse into a never ending pit/lava/ice etc.
* FoxChickenGrainPuzzle - Featuring a chicken, a caterpillar and a flower.
* GeniusLoci: One stage takes place around and inside a giant monster.
* HeroesPreferSwords even though they act more like boomerangs and you spend most of your time [[ThrowingYourSwordAlwaysWorks throwing them at stuff]].
* KillItWithFire - The most powerful attack in the game happens to involve fire.
* MoonLogicPuzzle - One of the animals you get is an armadillo that can be used as a platform to jump on (previously only used to cross water). One puzzle requires you to throw it into a bottomless pit where it will float unsuspended in the air allowing you to use it as a stepping stone.
* EvenBadMenLoveTheirMamas - Averted. The Leviathan decides that you're not a bad person when you protect an illusory copy of your mother when fighting him.
* ThePlan- The seer gives you the ability to talk to animals and creates a path to the past in an attempt to have you bring about world peace.
* PuzzleBoss: Many many many.
* RippleEffectProofMemory: Even if you change the effects of time, you remain the same.
* SetRightWhatOnceWentWrong with TIME TRAVEL.
* ShiftingSandLand: A desert setting with quicksand pits that don't suck you in but do spin you around and throw you. Necessary to reach some areas by slingshot jumping. Some pits have spikes in the middle.
* ShoutOut: SnoopDogg, Literature/LittleRedRidingHood, Film/TheWizardOfOz, and Literature/TheBible. The witch in Iris has this for her chant: [[TheManShow Ziggy...zaggy...oy...oy...oy.]]
* SlippySlideyIceWorld: Complete wiwth killer snow men. Melts into a water level.
* SpikesOfDoom - Averted, spikes only do minor damage.
* ThatsNoMoon - The first mountain range where you battle monsters? [[spoiler:It's a single giant monster. At the end, you talk to it at a time before it became so large.]]
* StockVideoGamePuzzle: All over the damn show.
* ThrowingYourSwordAlwaysWorks: The first technique you learn with it. Handy for cutting down grass (Familiar, no?) and necessary to beat some enemies/every damn boss. Even works as a boomerang.
* TowerOfBabel
* TurnsRed - The Octopus
* UnderTheSea: Complete with lack of oxygen. Can be ThatOneLevel.
* UpgradeArtifact: All the animals. Varies from fast running to an extra life to a rideable dinosaur. Many for your sword too. You can make it bounce of walls, guide it manually in flight, light it on fire or make it a freeze thrower.
* WantonCrueltyToTheCommonComma - The American version has some translation issues.
* WhatMeasureIsANonHuman: This game is all about the morality of killing monsters. Whether they deserve it, who starts the violence and how if effects their families.
* YouBastard: It is revealed that the monsters are intelligent and (initially) innocent, and you've spent the whole game committing genocide because [[FantasticRacism you assumed they deserved to die]]. An interesting premise, but [[BrokenAesop its presentation leaves much to be desired]].
