Video Game / Mugen Souls
aka: Attouteki Yuugi Mugen Souls
The next Compile Heart game developed under the direction of Keiji "Shin" Inafune (no, not that one).

The plot revolves around Chou Chou, a self-proclaimed god who wishes for world domination.

It was released in Japan on March 22, 2012, and by NIS America in Europe on September 28th, 2012 and in the U.S. on October 16th, 2012.

Not to be confused with M.U.G.E.N (though somebody might put this game's characters in there if they haven't already).

NOTE: Character page currently under construction.

A sequel was released, entitled "Mugen Souls Z" detailing the adventures of Syrma, who wants to become the "Ultimate God" once again with the help of Nao and Chou Chou.

Tropes Associated with the first game, Attouteki Yuugi Mugen Souls

  • Absurdly High Level Cap: Trailers show that 9999 is the highest level you can obtain in this game.
    • Absurdly High Damage Cap: Trailers show multi-hit attacks easily breaking ten-digit damage. At one point, a finishing move is shown to cause a grand total of over six-and-a-half billion HP damage! Even for a Nippon Ichi-associated RPG, I think that's a new record! note 
    • One of the screenshots on the website shows an attack doing over 933 billion damage.
  • Amnesiac God: Chou Chou has no idea who she is other than knowing that she's a god.
  • Bittersweet Ending: The Normal Ending. Chou-Chou abandons her peons in order to destroy Vorgis for good. While a post-credits scene shows they eventually found her somewhere at the edge of the universe, and can speak with her, she is unable to come back with them. Thankfully, it seems this ending isn't canon.
  • Bowdlerize: NISA decided to remove a mini-game that has controversial elements in it to avoid the AO ESRB rating (as discussed by a mod).
    • The PC port was going to avert this until Ghostlight was instructed by Steam that they could not keep the mini-game.
  • Calling Your Attacks: A variation with Soul. When casting a spell, he'll say "Spell" and then just say whatever it does. Such as "Spell! That magically teleports me safely to the castle!" Or "Spell! That heals all wounds in a flash of light!".
  • Censor Steam: Necessary for the various bath scenes, and in the Japanese version, a small extra mechanic to the hot spring minigame.
  • Character Customization: Trailers show that you're able to create different characters.
    • You can customize the clothing of everyone in the playable party, including the main characters.
  • Cloning Blues: A few of your party members get cloned for some bizarre reason in the post-game and you must fight them with their levels in the 1000 range. Good luck with that by the way, unless you've been Level Grinding at the Mugen Field.
  • Cool Ship: The Gcastle
  • Crush Blush: Ryuto gets this all the time when someone pokes fun of his crush on Chou-Chou.
  • Daddy's Little Villain: Subverted, Vorgis is NOT Belleria's father afterall, and she isn't much of a villain.
  • Defeat Means Friendship: Every single boss fight ends with Chou-Chou having the defeated person as their slave.
  • Departmentof Redundancy Department: The 7th World is called "Earthen Soil World". Gee, might as well say "Planet Planet Planet".
  • Disc One Nuke: it's pretty easy to wander into the Mugen Field at early levels, get into a random ship battle and get a huge EXP bonus, propelling your party forward 20 levels or more, pretty much steamrolling the rest of the main story for a time.
    • Generally that could be bad, but in a game where you can increase the level way higher than you should, it's a pretty good thing.
    • The equipment in some of the DLC packs are endgame level in terms of power and can be used as soon as you buy the DLC which can make the early levels a complete cakewalk. The Steam version of the game goes even further as it comes with some of said DLC packed into the base game.
  • Difficulty Spike: Chapter 8. And it only gets harder from there.
  • Does This Remind You of Anything?: Beat the clones of your party members in the post-game of the Golden Ending (good luck with that by the way) and look at the CG picture. That is all.
    • Also, the CG images that show up whenever someone goes into Syrmas coffin.
  • Duel Boss: Chou-Chou has a one-on-one match with Belleria.
  • Elemental Rock-Paper-Scissors: Personalities in Mugen Souls act as elements, and have corresponding strengths and weaknesses. Incompatible personalities will reduce the power of team attacks, adding a certain degree of strategy to party formation.
  • Epic Fail: In-Universe, Altis failed so hard at being a demon that she was reincarnated as an angel instead.
  • Expy: Chou-Chou's true form really looks like Goddess Madoka albeit with more...filling.
    • Ryuto has the same look, temperance and even English VA as Almaz, from Disgaea 3. (Who was also designed by Takehito Harada).
    • Syrma has the same personality and English VA as Plutia
    • Also Reu is a young child who has a surprising amount of energy and strength just like Peashy
  • Forgotten Friend, New Foe: Belleria is Chou Chou's first friend and she forgot all about it.
  • Guide Dang It: Getting the True Ending in typical Compile Heart fashion.
    • Granted, they do give you some ideas on how to get it after getting the Normal End, but figuring out what the threshold is is up to you.
    • 20% average charmlevel and at least 19% on all personalities. FYI.
  • Giving Someone the Pointer Finger: Chou-Chou loves doing this all the time. To a lesser extent, so does Altis.
  • Happiness in Slavery: Ryuto. To the max. This guy will never stop serving Chou-Chou if he can help it. Admittedly, Chou-Chou isn't a particularly harsh master... Most of the time...
  • Hates Being Alone: Chou-Chou. It the reason she created her world in the first place. She became even lonelier after realizing that she was only an observer of the world she made, not a participant.
  • Hoist by His Own Petard: Go ahead, go overload that Peon Ball. We'll wait to see your reaction.
  • Hot Springs Episode: Brings back the good ol' fashion minigames from Record Of Agarest War 2
    • Unusual for Compile Heart, this happens at the beginning of the game.
  • Informed Ability: Chou Chou Sadistic personality is actually not a real sadistic in fact she's more like of an arrogant queen, a real sadistic would be her Terse personality who shows absolute zero compassion to others and even managed to save Shirogane by torturing him so much that it excites him.
    • NISA has confirmed they are making significant changes to the character in order to make her more sadistic to a western audience.
  • Knight of Cerebus: Vorgis. Enough said.
  • Launcher Move: Some skills enable you to launch enemies up in the air.
  • Level Grinding: Say hello to the Mugen Field.
  • Literal Split Personality: Chou-Chou Infinite has split herself up into seven different personalities: Ditz, Hyper, Graceful, Terse, Sadistic, Masochist, and Bipolar.
  • Marshmallow Hell: In the ending, Belleria is hanging out at Chou-Chou's cleavage, who's now grown HUGE.
    • Never shown on-screen, but it's implied Chou-Chou ran face-first into Marina's chest when they first met.
  • Monty Haul: If you download the DLC; it's a Compile Heart tradition after all.
  • Nose Bleed: Ryuto makes one at the beginning of the game when he sees Chou-Chou and Altis naked in the bath. In fact, he gets these a lot.
  • One-Winged Angel: Vorgis gets a second form when he eats Belleria's gemstone to fuse with her to become a God of Destruction.
  • Person of Mass Destruction: Chou-Chou, the protagonist, is able to literally drop an Energy Ball the size of a freaking galaxy!
  • Pragmatic Adaptation: Nippon Ichi has announced some changes will occur to the US version of the game, presumably this will involve removing or editing the extremely lewd bathing minigame. And possibly the post-game post-fight CG of clones of your allies.
    • Confirmed. NISA has stated the bathing mini-game will be removed in it's entirety.
      • For more info on this (and link about it), see Bowdlerize above.
  • Sequel Hook: The game ends with Chou-Chou declares her new ambition to rule the entire universe. And Altis still wish to become a demon even after promoted into an even higher rank Angel.
  • Shout-Out: Lots.
  • Spell My Name with an "S": Even the website and the game can't seem to agree whether it's Shu-Shu or Chou-Chou. However, the official translation is the latter.
    • It should be noted that it's pronounced "Shu Shu" either way.
  • Spiritual Successor: It's basically a Hyperdimension Neptunia game. Of course Nippon Ichi's American branch is publishing it overseas...
  • Tactical Rock-Paper-Scissors: How the ship-to-ship combat works in this game.
  • Theme Music Powerup: When entering Fever Mode, you are treated to the game's themesong overriding the battle theme for as long as the Fever Mode lasts.
  • The Starscream: Vorgis to Belleria.
  • Unknown Rival: Well, more like "unacknowledged rival". Alys thinks she's Chou-Chou's rival, and while Chou-Chou does pity her, she knows that she is infinitely superior.
  • What Happened to the Mouse?: You never do get to actually visit/conquer Soil World. While it is freed from Vorgis' stomach in both endings, Chou-Chou and company never actually go there in the story or the postgame.
  • Word Salad Title: If you must know, the literal translation of this game is "Overwhelming Game Infinite Souls".
  • You Are Not Alone: The group gives Chou-Chou this treatment when she recalls how lonely she was as a god.

Tropes Associated with the second game, Mugen Souls Z

  • Attack of the 50-Foot Whatever: Peon Ball is replaced with Ultimate Soul, which summons a Chou Chou whose size varies based on Syrma's charm levels.
  • Breaking the Fourth Wall: After defeating Fake Ace Bellaria asks the player if they would want a reward for beating all of the clone characters.
  • Demoted to Extra: Chou-Chou loses her powers and gets shrunk down to a tiny chibi form in the beginning, handing the playable character status to Syrma.
  • Difficulty Spike: The very first "forced" encounter in the post-game consists of enemies with levels much higher than the True Final Boss.
  • Fetch Quest: Many of the Planet Spots require this; instead of asking the player for enough money to buy an item (as in the first game), they now ask for the item directly.
  • Flanderization: Zigzagged. Some characters' personality traits are downplayed (such as Alys losing much of her Valley Girl speak), while others are exaggerated (such as Marina's clumsiness).
  • Fun Size: Chou-Chou gets shrunk down after losing her powers because of Syrma's coffin malfunctioning.
  • I'm Taking Her Home with Me!: While Reu and Fake Reu are playing together Tsukika askes Shirogane if she can take Fake Reu with her.
    Tsukika: Um... Mister Shirogane...?
    Shirogane: No.
    Tsukika: I-I didn't say anything yet!
    Shirogane: You want to take the other one with us. No way.
    Shirogane: One is enough of a handful already. There's no way we can handle two.
    Tsukika: I-I'll take care of them both. I'll make sure to feed her, and walk her every day...!
  • Late-Arrival Spoiler: The game is a direct sequel, so this is to be expected. For starters, anything regarding Belleria.
  • Permanently Missable Content: The twelve worlds are destroyed in the Normal Ending, denying the player access to anything except the G-Castle, Mugen Field and the option to start New Game+.
  • Western Zodiac: The theme for the twelve worlds.
