History Characters / DecaDence

* {{Jerkass}}: He is a cruel and vicious bully whose rude to everyone. [[spoiler: Thus, Jill wasn't surprised to learn that Turkey betrayed them, whom she refers to as "The Biggest Asshole]].

The protagonist of the series, Natsume is a young girl who dreams of exterminating the gadoll threat and bringing peace to the world of Deca-Dence. In truth, she and the rest of the humans are labeled as NPCs by Deca-dence's system, with her being a bug at that, threatening the smooth operation of the game through being an extremely determined glitch.

* TheDividual: As one might expect from their ThemeNaming, they're always seen together, and tend to behave like a single being with two separate but closely-linked minds.

* FunnyAfro: Her cyborg body has a massive green afro with blue and pink polka dots which almost the same size as her body.

* FrickinLaserBeams: Munin has a powerful beam cannon which his Gear body fires from its mouth.

!!! '''Voiced by''': Michiyo Murase (Japanese)

* ImpaledWithExtremePrejudice: [[spoiler:He does this to Kaburagi's avatar at his home. Hugin's avatar ends up on the receiving end shortly after via ''metal Gadoll needle'' from Kaburagi's other avatar.]]

* BaldOfEvil: His Gear Avatar has a buzz cut which adds to his menacing, intimidating, and violent personality.

* AmazingTechnicolorPopulation: His skin used to be orange as a Ranker.

The strict administrator of Deca-Dence. He seeks to rid of "bugs" that threaten the System's game.

* AmazingTechnicolorPopulation: His gear avatar's skin is the same violet as his cyborg body.
* AnimalMotif: Ravens. He and his floating minion Munin are named after [[Myth/NorseMythology Odin]]'s ravens, he has a long, beaklike nose, and Munin's Gear body ''is'' a raven.

* EvilOldFolks: His Gear form is an old man with violet skin.
* FrickinLaserBeams: [[spoiler:Who would have thought that Munin could actually [[BreathWeapon fire a beam from its mouth.]]]]

* MorphicResonance: His silhouette is identical as both a cyborg and a Gear: tall, rectangular, head roughly level with his shoulders/"shoulders". He even has the same nose and sunglasses in both forms.
* MeaningfulName: The cyborgs Hugin and Munin are the roving eyes and ears of the System, just as the ravens Hugin and Munin were for Odin in Myth/NorseMythology.
* LackOfEmpathy: He has no sympathy for any of the humans or Gears.
* LargeAndInCharge: Towers over other cyborgs in both forms.
* LastChanceToQuit: [[spoiler:He gave Kaburagi one more chance to reafirm his loyalty to the System after he ruins Deca-Dence's current event and the rollout of its next expansion. Kaburagi rejects his offer and it doesn't end well for his avatar.]]
* SinisterShades: He wears dark TriangleShades in his cyborg form and Gear form.
* SinisterSchnoz: He has a long and narrow nose in both forms.
* TheStoic: There are no emotions in his cold and ruthless personality.
* YouHaveOutlivedYourUsefulness: He does this to any of the cyborgs that fail to comply to Solid Quake's rules and does this to "bugs", disruptive elements in the game. [[spoiler:And unfortunately this happens to Kaburagi's avatar after disrupting Deca-Dence's latest event.]]

* DragonInChief: The System's primary enforcer, ensuring that Deca-Dence's updates follow the script, its players keep Solid Quake in the black, and the humans stay oblivious.

* RewardedAsATraitorDeserves: [[spoiler:After selling out his fellow prisoners and explaining to Sarkozy's face that he was just using him, he ends up thrown into the gadoll excrement processing pit then blown up by Sarkozy's Heroicsacrifice.]]

[[folder:Gears]]
* AmazingTechnicolorPopulation: Some Gears have green, blue, or purple skin color. This is because they're essentially RPG avatars and one episode even has Natsume see a "Skin Shop" though she doesn't understand what it actually is. Their true forms also come in a wide variety of colors.
* CreatureHunterOrganization: As far as the humans are aware. Their government, the Power, is responsible for fighting the Gadoll threat, by training, arming, and providing incentives for the Gears and the Tankers who join them.
* ProudWarriorRace: The humans are led to believe they are descended from a race who are genetically engineered to fight the Gadoll and are ''very'' enthusiastic about their jobs. In truth, they're player avatars in an MMO.
* RemoteBody: All of them are avatars that the Solid Quake Corporation's cyborgs control from their home and workplace, a spaceship hovering over the Eurasian continent.
* YouGottaHaveBlueHair: The Gears come in a wide variety of inhuman and almost alien colors.

! Humans
[[folder:Tankers]]
* BadassNormal: Some of them are just regular, unmodified humans but are still perfectly capable of matching the Gears in fighting the Gadoll. Unfortunately, they're also ''far'' more vulnerable to casualties and don't have the benefit of just jumping into a new avatar. Kurenai exemplifies this as the leader and most talented fighter among them.
* MeaningfulName: Their name comes from their living in Deca-dence's oxyone tank. How their houses and animals don't end up washed away or destroyed if the city is knocked about and sends all that fluid crashing into them like waves is a mystery.
* RedShirt: Most of the Gears and the Power treat the human Gadoll hunters as little more than NPC allies and extras to make Gaddoll raids feel more alive and populated. It's notable that they only comprise a very small percentage of the Power's active force which is likely why they don't give them much thought.

[[folder:Kurenai]]
!!'''Voiced by:''' Creator/EriKitamura (Japanese), Creator/MorganGarrett (English)
One of the most skilled Tankers fighting alongside the Gears, Kurenai is a legend among them for her combat prowess and leadership skills both.

* TheAce: She's ''the'' best among the humans.
* AllAmazonsWantHercules: As shown in the aftermath of the underground raid in Episode 4, she is positively ''delighted'' at the prospect that Kaburagi is returning to active duty alongside her. Dialog from the rest of her squad implies she's been holding this torch for years and it hasn't flickered since then.
* AuthorityEqualsAsskicking: She is the leader of Tankers in the Power and is the strongest of them as well. Natsume looks up to her as her idol.
* BladeOnAStick: Her main weapon is a large spear capable of firing metal needles from the top and it has hooks on the side for slashing.
* DarkSkinnedBlonde: Kurenai has tanned skin and blonde hair.

* MorphicResonance: His silhouette is identical as both a cyborg and a Gear: tall, rectangular, head lower than his shoulders/"shoulders". He even has the same nose and sunglasses in both forms.
