A WidgetSeries of manga whose title means "Crossing of People" first started in 1978 by Tamori Yosuke. It's quite an extensive series, as it's formed by the following works:

* [=PopoloCrois=] Story Manga : Original manga published in 1978. It was finally compiled in three manga tomes.
* [=PopoloCrois=] Story Anime Pilot: An anime pilot that tells a story based on the manga. While it ultimately served as the basis for the first PSX game and the first chapter to the PSP version, it deviates largely from the manga, as well as the games also having some large deviations from it.
* [=PopoloCrois=] Story (PSX, 1996): First game in the PSX trilogy, telling Prince Pietro's story about his first adventure where he went to retrieve the Crown of Wisdom the [=GamiGami=] Devil had stolen from his father, as well as meeting his future friend the White Knight and his love interest Narcia. It ultimately becomes a quest to save Pietro's mother soul and stop an ancient evil from returning to the world and blanketing it in an eternal winter.
* [=PopoloCrois=] Story (Anime, 1998): An original story produced Creator/BeeTrain[[note]]with Creator/ProductionIG[[/note]], the same people as the animation for ''VideoGame/{{Xenogears}}'', ''Anime/{{Noir}}'', and many of the anime series to ''Franchise/DotHack''. Taking place prior to [=PopoRogue=], a mysterious girl called Hyu appears accompanied by two creatures after an accident with [=GamiGami's=] machines, her belonging to a long-lost race called the Wind Kind. While initially befriending Pietro, due to several circumstances she ends up siding with [=GamiGami=], stealing Pietro's powers and taking over [=PopoloCrois=], so Pietro departs in a journey to become stronger to take his kingdom back.
* [=PopoRogue=] (PSX, 1998): Second game in the PSX trilogy, taking place two years after the original [=PopoloCrois=] Story. The Kingdom of [=PopoloCrois=]and part of its surrounding lands were mysteriously whisked off to another world, so a search party leaves to castle to investigate, but ultimately only two of its members return. So Pietro ventures again to search for the missing members, but ends up getting wrapped up in solving the mystery of how [=PopoloCrois=] came to that world, searching also for his father, King Paulo who left the castle under unclear circumstances, and getting his kingdom back to its proper place.
* [=PopoloCrois=] Story II (PSX, 2000): With its prologue being set after [=PopoRogue=] and its main story taking place three years after it, a Goddess has started wreaking havoc throughout the world in search for four ancient stone tablets that will allow her to remake the world however she wishes, and Pietro, now older and wiser, must team with his friends once again to save [=PopoloCrois=] and the world from destruction.
* [=PopoloCrois=]: Hajimari no Bouken ([=PS2=], 2002): Taking place fifteen years after [=PopoloCrois=] Story II and featuring Pietro and Narcia's son Pinon as the protagonist, this game also marked the jump to 3D for the series. After the elements start acting strangely, Pinon ventures into an old shrine located near the castle looking for adventure, but upon getting attacked by a monster, his powers awaken and he meets a strange creature called Papuu. He also meets a mysterious girl called Luna and a rowdy boy called Marco, and them three end up joining together to finding out why the elements are out of control and what is the cause for the darkness that threatens to envelop [=PopoloCrois=].
* [=PopoloCrois=] (Anime, 2003): An anime series that serves as an expanded retelling of [=PopoloCrois=]: Hajimari no Bouken and [=PopoloCrois=]: Tsuki no Okite no Bouken, predating the latter's release by a few months. It was produced by Creator/TMSEntertainment, the studio behind WesternAnimation/TinyToonAdventures.
* [=PopoloCrois=]: Tsuki no Okite no Bouken ([=PS2=], 2003): A direct sequel to [=PopoloCrois=]: Hajimari no Bouken that takes place a few months after it. After going to meet Luna once again, Pinon and Marco return to [=PopoloCrois=] to see it has turned into stone, and after hearing only a legendary relic called the Lunar Drop can undo the petrification, Pinon, Marco and Luna depart for the sea in the ship belonging to Pietro's younger sister, Elena to look for the Lunar Drop, not knowing this will also lead into awakening an ancient evil that is hellbent in leading the world to its destruction.
* [=PopoloCrois=] (PSP, 2005): A condensed adaptation of [=PopoloCrois=] Story and [=PopoloCrois=]Story II, which also includes an interlude to bridge both games. This is the only version released of these games outside Japan.
* [=PopoloCrois=] Story: Card Quest (Mobile, 2009): A card game RPG released for mobile phones in Japan.
* [=PopoloCrois=] Story: Yume to Kizuna no Bouken (Browser, 2011): A social game developed for the entag! social network. Its service was terminated in June 2013.
* [=PopoloChronicle=] (light novel, 2015): A duo of light novels set several years into the past that follow the adventures of a boy called Marcosias. It also features King Paulo, Queen Sania and Esperanza, the younger brother of the Dragon King.
* Return to [=PopoloCrois=]: A Story of Seasons Fairytale (3DS, 2016): Crossover with the Story of Seasons series, and first and so far only game in the series to see release in a Nintendo console. Taking place between [=PopoloCrois=] Monogatari II's prologue and main story, Pietro finds himself whisked off to another world called Galariland, and now he must find a way to go back to [=PopoloCrois=], all while also tending to an abandoned farm he found and started using as his home away from home.

Did we mention that this is most ''definitely'' a WidgetSeries?

----
!!''[=PopoloCrois=]'' provides examples of:

* ActionGirl: Kai, Jilva, Leona.
* AdaptationDistillation: The only game to receive an overseas release (The PSP Title) is a combined adaptation of the first and third Playstation games. Most of the first game's content is cut or compressed, but the story is expanded a little with a side-story set in between the two games included. On the other hand, the second game ([=PopoRogue=]) is completely disregarded excepting for some of its characters and monsters being included as summons.
* AdaptationDyeJob: Seriously, Pietro's hair changes in every adaptation, like the creators can't decide what his hair color should be! In the games, it's brown, in the 3 minute pilot, it's orange, in the 1998 anime, it's blonde, and in the 2003 anime, it's brownish blonde.
** On that same order of ideas, the first anime series takes a lot of liberties with the characters' color schemes: Pietro also has greenish eyes instead of brown, Queen Sania has brown hair instead of reddish and her dress is mostly blue instead of red, King Paulo's coat is purple instead of green, Narcia's eyes are green instead of blue and [=GamiGami=] is missing the gauntlets on his hands.
* AnachronismStew: One half is a MedievalEuropeanFantasy... alongside ambiguously Roman areas (Which actually isn't ''too'' implausible)... alongside any area the [=GamiGami=] Devil lives in with robots and ''modern-day-Japanese rooms''.
* AnnoyingYoungerSibling: Elena
* TheArcher: Leona
* BalefulPolymorph: Happens several times. They get better.
* BilingualBonus
* BittersweetEnding: Averted. [[spoiler: Pietro gets one wish for saving the world... guess what he wishes for.]]
* CerebusRollerCoaster: Given the adaptation of two games, this is a given. Both start surprisingly light-hearted (Given the artstyle!) but it quickly gets ''real'', and when it gets real... ''you know it''.
* CharacterDevelopment: Narcia gradually grows closer to Pietro and accepts [[spoiler: Her heritage, as well as the fact that their relationship didn't ''need'' to be forbidden]]
** Jilva. At first she's a bit of a SpoiledBrat with her father ''clearly'' favouring her.. but her mother is shown to be a SternTeacher who can keep her in line, and her adventures with Pietro teach her to become a member of the ActiveRoyalty.
* DanceBattler: Jilva.
* DarkerAndEdgier: The second game.
* DullSurprise: Leona's english voice.
* EarnYourHappyEnding: Do Pietro and Pinon ''ever'' have to go through ''hell'' to get their happy endings.
* EldritchAbomination: The Ice Demon, Dream Demon Id, Barbaran, Yasm, Zephys.
* EverythingsBetterWithPrincesses
* EverythingsBetterWithSamurai
* EvilIsHammy: [=GamiGami=]. [[LargeHam "Otoko no ROMAAAAAN!!"]]
* EvolvingWeapon: The Dragon Sword. Pietro's starting weapon and ''ultimate'' weapon. It can also be powered up further in some of the games by collecting Dragon Orbs.
** Averted in [=PopoRogue=] and Return to [=PopoloCrois=]: A Story of Seasons Fairytale, as the Dragon Sword (renamed to Dragonlord's Blade in the latter) lost its evolving properties in both games.
* {{Expy}}: Pietro looks oddly similar to [[Franchise/TheLegendOfZelda Link]]. This hasn't gone unnoticed by fans.
* FairFolk: [[spoiler: Narcia]].
* FullContactMagic: Jilva's special attacks.
* GameplayAndStoryIntegration: The player is not able to bring Narcia around any areas with salt water.
* GrandTheftMe: Pietro's father
** [[spoiler: Maira tries it to Pietro... but then possesses his ''mom'' instead!]]
* GettingCrapPastTheRadar: A small but EXTREMELY subtle instance appears in episode 11 of the 1998 anime where a certain character is '''almost''' DrivenToSuicide, and the anime implies said character attempts it THREE times.
** In the English version, the fact that [=GamiGami=] is obsessed with Narcia. That would really ''REALLY'' get a lot of eyebrows if this wasn't written in Japan.
* GratuitousFrench
* GuestStarPartyMember: The only true example is Kai. Because she is also Narcia, it's impossible for her to join permanently.
** Kai is available as an alternate form to Narcia near the end for the original [=PopoloCrois=] Monogatari for PSX, but it's a hassle to use her because that requires Narcia to remain inactive for two whole turns (one for the transformation, and one in Stop status) due to the mechanics the transformation includes.
* HalfHumanHybrid: Pietro is half dragon. Notable in that his ''mother'' is the dragon.
* HeelFaceTurn: Gami Gami Devil, [[spoiler: Maira performs one right at the end.]]
* HeroicBSOD: Pietro has got three so far [[spoiler: when he released the Ice Devil accidentally in the world and his mother was taken away to be used as a receptacle for said devil, when he and the White Knight kill the earth dragon, and the worst one of them all, when Queen Sania was killed by Maira.]].
** [[spoiler: The king of gods himself had it when he punished Maira]]
* HeroicSacrifice: [[spoiler: Narcia attempts one. Pietro's mom does it as well.]]
* HeroesPreferSwords: Pietro
* HurricaneKick: How Jilva fights.
** Kai as well.
* JokeCharacter: Three in fact: Gon, Don, and Gabo.
** LethalJokeCharacter: See MagikarpPower.
** In-Universe example, the last of Maira's minions, Boxie, despite being a DamageSpongeBoss.
* KidHero: Pietro and Narcia are ''ten'' during the first game.
* MagicDance: Jilva is able to perform some of these.
* MagikarpPower: Gabo. Ungodly weak and useless, essentially being an EleventhHourSuperpower... that is if you decide to go through all the process of babying him.
* MarathonBoss: Almost every boss if one doesn't take advantage of charged attacks.
* MissingMom: Zig-zagged. Pietro rescues his mom in the first game, [[spoiler: loses her... only to get her back.]]
* NoExportForYou: The ''entire'' franchise... sans the PSP version and the Story of Seasons crossover. The first anime received a dub and was broadcast on some Latin American countries and Italy, but only that.
* NoNameGiven: White Knight.
* OlderThanTheyLook: Would you believe that these characters are supposed to be teenagers? The voiceacting (Pietro has the same voice as when he's a ten year old) doesn't help either.
* OnlyKnownByTheirNickname: [=GamiGami=] Devil, White Knight.
** NoNameGiven: White Knight.
* PettingZooPeople: The people of Bryonia.
* ThePowerOfFriendship: One of the ''key'' themes.
* ThoseTwoGuys: Gon and Don. They're ''completely'' useless (excepting for [=PopoRogue=], where they were included as bonus characters capable of equipping any weapons and armor, and learning all special skills).
* TrickArrow: Leona.
* PickyEater: When [=GamiGami=] dresses Jilva as Narcia, some of his robots try to make her eat her vegetables, which Jilva doesn't like. As this is a Japanese trope, these vegetables that Jilva will not eat are, of course, carrots and green peppers.
** StockYuck: Green peppers and carrots are fairly common versions of this in Japanese media.
* PowersViaPossession: Pietro's father when he becomes the Dark Lion King
* QuirkyMinibossSquad: The Ice Demon and Maira ''both'' have them.
* RedMage: Narcia has healing but she gets a lot of attacking and buffing abilities too. She also shares this role with Jilva, who veers more towards the physical side of the trope.
* RoyalsWhoActuallyDoSomething: Pietro, [[spoiler: Narcia]]. Jilva at first is an idle royalty, but she becomes a member of active royalty through the game. Not to mention, Pietro's parents are pretty active.
* [[spoiler: SelflessWish]]
* SpinAttack: Jilva.
* SpiritualSuccessor: There are QUITE a few similarities between this series and the BreathOfFire series, most notably the fact that the protagonist is half dragon and gains powers from it.
* SpoiledSweet: Jilva's CharacterDevelopment.
* StalkerWithACrush: [=GamiGami=] to Narcia.
* SternTeacher: Jilva's father is a complete pushover... however Jilva's mother, on the other hand, will ''not'' let her get away with the stuff her father does!
* SummonMagic: Both Eastern ''and'' Western Summon magic, unusually enough!
* TakenForGranite: [[spoiler: Julius]]
** Some other characters turn to stone and fall to pieces... but that's more metaphorically speaking rather than ''literal'' and is PlayedForLaughs.
* TomboyPrincess: Zig-zagged with Jilva - Despite dressing feminine and engaging in activities such as dancing (To be fair, dancing and music are part of her culture), she is primarily an ''attacker'', and is more of a RedMage focusing a little more on offense and melee.
* TwoAliasesOneCharacter: Narcia is Kai
* [[spoiler: VictoriousChildhoodFriend: Narcia]].
* VoluntaryShapeshifting: Kai and Narcia thanks to a MacGuffin.
* WeaksauceWeakness: Forest Witches will turn into seafoam if they come in contact with saltwater.
* WidgetSeries: Oh ''yes''.
* {{Wutai}}: There is a Japan-themed area where Kimendoji can be recruited late-game.
