* BeCarefulWhatYouWishFor: Like all magician groups, the Yotsuba use eugenic techniques and genetic engineering to ensure their offspring have increasingly strong magic. Unfortunately, they were the first group to experience the logical [[PersonOfMassDestruction consequence]] of such techniques.
* BigScrewedUpFamily: The current head of the clan wants to destroy the world through [[spoiler: [[RoyalInbreeding engagement]] between her nephews, for which she manipulates incestuous feelings her younger niece to her own brother]]. In addition, the last head has arranged a bloody vendetta against a secret organization that kidnapped his daughter, and as a result of this, the clan killed 4,000 people while losing only 18 of its own.
* BlackAndGreyMorality: The morally worst threat is Maya, who wants to destroy '''everything'''. A little up from her are the majority of the clan, who enable slavery and child abuse because it's convenient. And up from ''them'' are the protagonists, who are vaguely interested in preventing the above atrocities. But all of these characters are terrible in their own ways.

* DarkSecret: Factions are supposed to openly declare the existence of any strategic-class magicians within them, but the Yotsuba didn't do this when Tatsuya was born.
* DidYouJustPunchOutCthulhu: It took a few years of preparation, but the Yotsuba managed to mutilate a PhysicalGod. Mutilated it ''so hard'' that even a decade later he is still essentially their attack dog.
* TheDreaded: Even USNA, the strongest country ''in the world'', fears them.
** [[spoiler: In volume 31, every government and military InUniverse agrees that Tatsuya and, by extension, the Yotsuba, has powers equal or greater than the 4 World Superpowers.]]
* EpicFail: Every attempt the Yotsuba make to fix their mistakes only makes things worse, because a) they refuse to acknowledge that they were in the wrong in any way, and b) those attempts always involve 'fucking with the natural order ''again'', in the hope that ''this time'' that will work'. Special mention goes to the FaceHeelTurn of [[spoiler:Miyuki]], who was literally created for the sole purpose of supporting the family's interests.
* EvilCannotComprehendGood: Miya readily tells a ''thirteen-year-old child'' that the Yotsuba MindRape[=d=] Tatsuya, because she genuinely doesn't see (or doesn't care about) the inhumanity of such an act.
** She is quite literally incapable of this, due to her limited emotions, after suffering backlash from her Mental Design Interference on Tatsuya's emotions, making her lose a portion of the potency. Also, she has a unique view on the mental structure of the brain, as a required secondary power to her Mental Design Interference, so she might not see anything wrong with this either way.
* EvilCounterpart: To the Yoshida family, who work alongside eldritch spirits beyond human comprehension instead of enslaving them.
* FamilyHonor: The Yotsuba really don't like showing weakness to outsiders. Hence the global death crusade against Maya's kidnappers. (And- knowing the Yotsuba- probably a lot of innocent employees too.)
* FourIsDeath: Yotsuba Family are descendants of the infamous 4th laboratory.
* FreudianExcuse: Several decades before the start of the series, the Yotsuba's then-heiress and figurehead was [[RapeIsASpecialKindOfEvil kidnapped and tortured]]. Their fear and [[MightMakesRight shame]] twisted them into becoming [[NeverBeHurtAgain even more paranoid then they had been before]].

%%* Hypocrite: Their treatment of Tatsuya is similar to how {{Muggles}} treated the first magicians, [[HistoryRepeats centuries ago]].
* InTheBlood: Ruthlessness. Not all Yotsuba are evil, but they only care for their allies and subjects. Anyone else is expendable.
* ALessonLearnedTooWell: They made it so Tatsuya would ([[MoralityChain probably]]) not destroy the world because of emotional extremes. However, he may now destroy the world because he is sociopathic.

* NamesToRunAwayFromReallyFast: {{Lampshaded}} by Miyuki when she planned to use her identity as a Yotsuba when a politician was bothering her. Also [[spoiler: by Volume 17, only Erika and Leo amongst his closest friends never feared Tatsuya when his identity as Yotsuba was revealed.]]

So they enslaved him, made him into a ruthless killing machine, etc, and then several years later someone else frees Tatsuya and he is not pleased with the family who made his life a living hell.
%%* AlwaysABiggerFish:
* AsskickingEqualsAuthority: The Yotsuba are always competing, all the time. Just showing up at one of their coronation ceremonies is an accomplishment, because it means you managed to dodge or fight off all the rivals trying to stop you from getting there.
%%* BadassFamily
* BeCarefulWhatYouWishFor: Like all magician groups, the Yotsuba use eugenic techniques and genetic engineering to ensure their offspring have increasingly strong magic. Unfortunately, they were the first group to experience the logical [[PersonOfMassDestruction consequence]] of such techniques.
* BigScrewedUpFamily: The current head of the clan wants to destroy the world through [[spoiler: [[RoyalInbreeding engagement]] between her nephews, for which she manipulates incestuous feelings her younger niece to her own brother]]. In addition, the last head has arranged a bloody vendetta against a secret organization that kidnapped his daughter, and as a result of this, the clan killed 4,000 people while losing only 18 of its own.
* BlackAndGreyMorality: The morally worst threat is Maya, who wants to destroy '''everything'''. A little up from her are the majority of the clan, who enable slavery and child abuse because it's convenient. And up from ''them'' are the protagonists, who are vaguely interested in preventing the above atrocities. But all of these characters are terrible in their own ways.
* BlackSite: The 4th institute and any Yotsuba residencies. Also, given they're specialized in black ops, government agencies gives them access to their own black sites.
* BrainwashingForTheGreaterGood: They ''say'' this, but they jumped on the chance to use Tatsuya after his MindRape, so...
* DarkSecret: Factions are supposed to openly declare the existence of any strategic-class magicians within them, but the Yotsuba didn't do this when Tatsuya was born.
* DidYouJustPunchOutCthulhu: It took a few years of preparation, but the Yotsuba managed to mutilate a PhysicalGod. Mutilated it ''so hard'' that even a decade later he is still essentially their attack dog.
* TheDreaded: Even USNA, the strongest country ''in the world'', fears them.
** [[spoiler: In volume 31, every government and military InUniverse agrees that Tatsuya and, by extension, the Yotsuba, has powers equal or greater than the 4 World Superpowers.]]
* EpicFail: Every attempt the Yotsuba make to fix their mistakes only makes things worse, because a) they refuse to acknowledge that they were in the wrong in any way, and b) those attempts always involve 'fucking with the natural order ''again'', in the hope that ''this time'' that will work'. Special mention goes to the FaceHeelTurn of [[spoiler:Miyuki]], who was literally created for the sole purpose of supporting the family's interests.
* EvilCannotComprehendGood: Miya readily tells a ''thirteen-year-old child'' that the Yotsuba MindRape[=d=] Tatsuya, because she genuinely doesn't see (or doesn't care about) the inhumanity of such an act.
** She is quite literally incapable of this, due to her limited emotions, after suffering backlash from her Mental Design Interference on Tatsuya's emotions, making her lose a portion of the potency. Also, she has a unique view on the mental structure of the brain, as a required secondary power to her Mental Design Interference, so she might not see anything wrong with this either way.
* EvilCounterpart: To the Yoshida family, who work alongside eldritch spirits beyond human comprehension instead of enslaving them.
* FamilyHonor: The Yotsuba really don't like showing weakness to outsiders. Hence the global death crusade against Maya's kidnappers. (And- knowing the Yotsuba- probably a lot of innocent employees too.)
* FourIsDeath: Yotsuba Family are descendants of the infamous 4th laboratory.
* FreudianExcuse: Several decades before the start of the series, the Yotsuba's then-heiress and figurehead was [[RapeIsASpecialKindOfEvil kidnapped and tortured]]. Their fear and [[MightMakesRight shame]] twisted them into becoming [[NeverBeHurtAgain even more paranoid then they had been before]].
* GoneHorriblyRight: Tatsuya's power stems from the Yotsuba's wishes for a savior, and Maya's wishes for a destroyer after the incident at Dahan.
%%* Hypocrite: Their treatment of Tatsuya is similar to how {{Muggles}} treated the first magicians, [[HistoryRepeats centuries ago]].
* InTheBlood: Ruthlessness. Not all Yotsuba are evil, but they only care for their allies and subjects. Anyone else is expendable.
* ALessonLearnedTooWell: They made it so Tatsuya would ([[MoralityChain probably]]) not destroy the world because of emotional extremes. However, he may now destroy the world because he is sociopathic.
* MealTicket: [[spoiler: In the sequel, most people see the Yotsuba Family as this due to Tatsuya's Magian Company attracting various investors.]]
* NamesToRunAwayFromReallyFast: {{Lampshaded}} by Miyuki when she planned to use her identity as a Yotsuba when a politician was bothering her. Also [[spoiler: by Volume 17, only Erika and Leo amongst his closest friends never feared Tatsuya when his identity as Yotsuba was revealed.]]
* PersonalityPowers: All their magics reflect some part of entropy: ice, darkness, amputation of memories or emotions, AntiMagic...
* PowerEqualsRarity: Its resources are channelled into strange, unprecedented biological projects instead of expanding the clan through more typical ways.
* RedBaron: The Untouchables.
* TheDragon: [[spoiler: In volume 32, Yotsuba are under the command of [[TheOmniscientCouncilOfVagueness The Senate]], in which High Level Government officials take part. [[TheTeamBenefactor In return, they provide the Yotsuba whatever they need.]]]]
* TheSpartanWay: Yotsuba magicians and their guardians are trained this way, making their combat prowess levels above any other clans.
* TokenEvilTeammate: They are the Clan that specializes in black ops and information control [[note]]though every Clan participates in those things to some extent[[/note]]; not coincidentally, [[spoiler:their bloodline grants the ability to MindRape]]. Although given their increased attempts to dominate Japan's magicians, they may not be a 'teammate' anymore...
* ATragedyOfImpulsiveness: They panicked when they realized [[PersonOfMassDestruction what]] was gestating in Miya's womb, so they created a second, slightly less apocalyptically-powerful child to follow the first one around and control it. Unfortunately, no one is around to control ''that'' one.
* VetinariJobSecurity: The Yotsuba can singlehandedly turn the tide of whatever conflict they join, and they are not shy about milking this fact for all it's worth.
* QualityOverQuantity: They lacked numbers compared to the other clans yet their combat prowess makes it up for it. Taken {{Up To Eleven}} when they even have the [[PersonOfMassDestruction God of]] [[RedBaron Destruction.]]
* WardensAreEvil: [[spoiler: A side story reveals that one of the trainings for Yotsuba magicians was to guard [[TheAlcatraz a volcanic island prison]] [[BlackSite where very dangerous individuals are held.]]]]

* {{Miko}}: Was forced to dress as one in order to [[spoiler: seal the parasite, as they believe that dressing as opposite sex will increase the effect since they don't have enough people to perform the spells]]. He was not amused.
* NiceGuy: One of the nicest Yotsuba out there (his father said that he is too kind to lead the Yotsuba clan). Though he wouldn't mind [[BlueAndOrangeMorality attacking and blackmailing anyone who opposes them]].
* OneManArmy: [[TookALevelInBadass A few examples]]:
** Defeated a group of armies/humanists in his introduction without even touching them.
** [[spoiler: Annihilated the security forces who were trying to arrest Minami in less than 5 minutes during the Steeplechase arc]].
** [[spoiler: Has to fight parasite dolls all by himself after confronting Minoru, since Ayako's magic isn't suited to combat. But he was forced to retreat when he realizes Direct Pain doesn't have any effects on [[SealedArmyInACan parasite dolls]] ]].
* {{Sadist}}: Hashibami Yuki called him this, due to the nature of [[spoiler: his innate magic, Direct Pain]].
%% TagTeamTwins: With Ayako.
* TookALevelInBadass: Was presented as a CheerfulChild in the Reminiscence arc. Now he is a competent fighter and a great leader. [[spoiler: He is also able to corner Parasite!Minoru (which the 3 Saegusa members have trouble dealing with) all alone and would have win if not for Minoru launching a suicide attack against him]]
* TroublingUnchildlikeBehavior: He talks about assassination like it was a normal topic for a high school student to talk about. {{Justified}} as he's part of a clan specializing in doing wetwork for various clients.
* WholesomeCrossdresser: Much to his displeasure.
