History Characters / FutureDiarySupportingCharacters

* KnifeNut: At first, when she tries to stab Yuki, but she [[HeelFaceTurn she gets better]].

* DoesThisRemindYouOfAnything: Akise briefly having Yukiteru's physical appearance at the beginning of the ''Redial'' OVA is almost definitely a [[MythologyGag reference to Paradox]].

%%* ZettaiRyouiki

* JerkassGod: He sits back and lets the players kill each other, only interfering due to players not playing by the rules. He doesn't care about how the battle game will emotionally scar the Diary users. He then deconstructs every choice of free will that Akise ever did, even his love for Yuki, that being all programmed.

* TheDogWasTheMastermind: The true villain, whom Yuno and Deus Ex Machina himself were nothing more than pawns to, is... the [[CuteIsEvil cute little]] PluckyComicRelief girl who barely showed up in the main story at first, only appearing in {{Omake}}s and side material.

* BigBad: She can be considered this for the whole story - while technically subservient to Yuno, she also [[DragonInChief is more powerful, more clear-headed, and even manipulates Yuno according to her own desires.]]

* BadassGay: While he claims he isn't gay, he has definite romantic feelings for Yukiteru, and he's a BadassNormal who can outsmart half the major cast.

* TheCorrupter: For the Diary Holders, as she is more direct in turning them all into a BigBadEnsemble in an EvilVsEvil war.

* AlwaysSaveTheGirl: In ''Paradox'', in regards to Yuki and Tsubaki (though it might be just part of his plan in the latter's case).

* BackFromTheDead: The ''Redial'' OVA imply that 3rd-world Akise is 2nd-world Akise.

* HiddenHeartOfGold: Towards Yuki.

* ILetYouWin: Implied to have intentionally lost to Yuno in the Redial OVA, as she finds the sword she took from him allowed her to go further in when her path was blocked.

* HeroicAlbino: Has shown shades of this in the actual series. Played straight in ''Paradox''.

* PurpleEyes: See image a above.

* CosmicKeystone: Without him, the universe collapses made worse since he's dying.

* MetaphoricallyTrue: When Yukiteru asks him to revive Rea, Deus replies than it's impossible. When questioned why that is so, he states that he's dying and losing his power. While he doesn't outright lie, the way he phrases his reply makes it look like it's only impossible for him in particular and that the new god will be able to revive Rea; he doesn't mention that even a god would only be able to revive the body but not the soul. As his later conversation with Akise shows, it's not that Deus himself isn't aware of this.

* RulesLawyer: He puts a large emphasis on the rules he found Tenth's avoidance to be a deviance from the game, so he planned accordingly, as well as planning against Mur Mur once it's clear that she favors Yuno.

* HoistByHerOwnPetard: Saika's abuse is what drove Yuno insane and lead to her killing Saika and Ushio.
* KarmaHoudini: Saika in the 3rd-world. She does become a lot more loving of Yuno, but she still doesn't face any punishment for locking her in a cage and feeding her grass over minor faults (like missing curfew).

* TheDragon: Towards the end, she fights off the [[EmpoweredBadassNormal empowered Minene]] while Yuno arranges her life in the 3rd-world.
* DragonInChief: Yuno might be the goddess in the 1st-world who arranged this whole mess but Mur Mur is more competent concerning knowledge of space and time, and she is the one who gives advice to Yuno on how to continue the Survival Game. Also unlike Yuno, she has the ability to travel through time, and it is thanks to Mur Mur that Yuno was able to get into the 3rd-world. She also is much stronger than Yuno in the battle, and certainly has no doubts about continuation of the Survival Game. Throughout the whole series, she has tried to ensure Yuno's victory while Yuno herself didn't want to win the Survival Game again (before Yukiteru refuses to kill her). And also take into account that if it were not for Mur Mur, then Minene would have had no trouble killing Yuno when she had the chance.

* AllPowerfulBystander: Despite being a literal [[PhysicalGod divine level]] RealityWarper [[DimensionLord who controls everything about his dimension]], he does not directly interfere with the games for two reasons, 1) it's against the rules he's set up only interfering when knowing someone is bypassing the rules and 2) [[SecretlyDying he's slowly decaying]].

* CosmicKeystone: Without him, the universe collapses made worse since he's SecretlyDying.

* SecretlyDying: The reason why he started the game in the first place is because he's going to die soon and needs to find a successor.

* GodIsFlawed: He leans a bit closer to this in that he wants the survival game to play out fairly between the players and without outside intervention from himself or Mur Mur, and honestly can't see the problem in it so long as he's kept entertained and his successor is chosen. He is also very willing to cancel the whole game entirely when John Balks decides to stop the Future Diary Project from developing further in the 3rd-world.

* PalsWithJesus: Pretty much everyone who is able to visit the Hall of Causality is this to him since he's a pretty chill God. Special mention goes to Yukiteru though, whom Deus clearly favors over everyone else. Another is with Balks as the two of them together founded the Survival Game.

* TakingTheBullet: Heartbreakingly, to protect Minene. Yuki gets blamed for it since he used Minene and Nishijima as decoys to clear the path ahead to go to John Balks.

* To Akise, whose she's more dickish to and Akise being one of the few people who knows her true nature, especially in ''Paradox''.
* She also becomes one to Minene in the final battle, with them duking it out while Yuki and Yuno have their own conflict.

NoHoldsBarredBeatdown: She gives one to Minene in her unrestrained form.

* ArchEnemy: She becomes this to Minene in the final battle, with them duking it out while Yuki and Yuno have their own conflict.

* ButtMonkey: In ''Paradox''. Might lean into being TheChewToy depending on the fans that read the story.

* ItAmusedMe: Her main motivation for repetition of the Survival Game, not counting her devotion to Yuno. In fact it maybe even more than her devotion to Yuno considering what she shows Yukiteru the past events of the 1st-world to "make the game more interesting" even despite that Yuno was ''isn't'' want to Yukiteru saw this.

* ManipulativeBitch: She was manipulated the Fourth, telling to him ahead of time about his son's illness in order to speed up the game. And also manipulated Yukiteru, telling him that his mother can be returned to life if he becomes a god in order to motivate him to take a greater part in the game.

* DragonInChief: Yuno might be the goddess in the 1st-world who arranged all this mess but Mur Mur is more competent as concerning knowledge of space and time, and she is the one who gives advice Yuno how to continue the Survival Game. Also unlike Yuno, she has the ability to travel through time, and it is thanks to Mur Mur, Yuno was able to get into the 3rd-world. She also is much stronger than Yuno in the battle, and also in unlike Yuno she has no doubts about continuation of the Survival Game. She throughout the whole series tried to ensure Yuno's victory while Yuno herself didn't want to win the Survival Game again (before Yukiteru refuses to kill her). And also take into account that if were not for Mur Mur, then Minene would have had no trouble killing Yuno when she had such a chance.

* TheAtoner: In the ''Redial'' OVA, the 1st-world Mur Mur is trapped by the 3rd-world's incarnation with the first Yuno's memories. Through this she realises the enormity of pain she had caused and contacts the third Yuno via a keychain replica of herself to give her a proper happy ending.

%%* CloudCuckooLander

* DragonInChief: Yuno is maybe was goddess in the 1st-world who arranged all this mess but Mur Mur is more competent as concerning knowledge of space and time, and she is the one who gives advice Yuno how to continue the Survival Game. Also unlike Yuno, she has the ability to travel through time, and it is thanks to Mur Mur, Yuno was able to get into the 3rd-world.
