Illumi zeigt größtenteils nur sehr wenig Ausdruck. Im Gegensatz zu seinem ausdruckslosen Verhalten spricht Illumi oft in einem etwas freudigen und abwesenden Ton. Er ist im Allgemeinen ein steiniger, rücksichtsloser Mensch mit einer extrem kalten Denkweise und reflektiert sich ausschließlich auf seine eigenen Interessen. Trotzdem hält er eine verdrehte und übersichtige Liebe der Liebe zu seinem jüngeren Bruder, Killua ; Dies manifestiert sich so weit, dass er seine Nen-Fähigkeit benutzte, Killua zu kontrollieren, um sein Überleben und sein Gehorsam zu gewährleisten. Killua zu glauben, dass das einzige, was ihn aufrechterhalten, die Dunkelheit war und dass er nur Freude daran erlangen konnte, den Tod anderer zu verursachen. Als Mittel, um seinen kleinen Bruder zu schützen, implantierte Illumi eine Nadel in Killuas Gehirn und zwang die letztere, vor Schlachten zu rennen, er war nicht sicher, ob er gewinnen konnte. CITE_NOTE-CHAP219-6 "> Illumi kümmert sich um die meisten Mitglieder der Familie Zoldyck. Er ist bereit, Alluka 's Macht zu sein, selbst wenn es sein Leben kostet. Er hat jedoch erklärt, dass Familienmitglieder während einer inneren Mission nicht töten dürfen (eine Mission, bei der es einen internen Konflikt gibt), sondern unterstellt, dass es ihm gut wäre, Alluka zu töten und Aluka nicht als Mitglied der Familie zu betrachten. Während Illumi viele menschliche Gefühle ohne ein Gefühl des Verlangens nicht ohne Verlangen erscheint, da er Alukas Wunsch-Granting-Fähigkeit sehr schlägt. Tsubone impliziert, dass Illumis das unruhige Ambition von Illumis kontrolliert hat, um Allukas Kraft zu kontrollieren. Irgendwann bildete Illumi eine ungewöhnliche Beziehung zu Hisoka, die er als "Give-and-Take" bezeichnete. Er kam einmal zu Hilfe des Magiers, indem er für ihn als Doppel in der phantom troupe sacke "sacke, um zu finden, um zu finden, um zu finden, um zu finden, um zu finden, um zu finden, um zu finden, um es zu finden, um zu finden, um zu finden, um zu finden, um zu finden, um zu finden, zu einem Doppel -Nofollow" -Behnen -Fandom. -s -Versteck, stand, stand. rel = "noopener norferrer nofollow" href = "https://hunterxhunter.fandom.com/wiki/chrollo_lucilfer"> chrollo . Als Hisoka jedoch Illumi fragt, ob es in Ordnung wäre, wenn er Killua töten würde, zeigt Illumi eine schreckliche Seite von sich selbst und fragt, ob Hisoka dann sterben will. Sein Verhalten und sein Blutverschenken waren sehr ähnlich wie Hisoka auf Illumis Unentschlossenheit darüber reagierte, ob er , wobei er als A -Hisci -Hiscs -" -S -Hiscs -"-S -von A -Droh mit A -Hiscs -" -Mesibilen, reagierte, reagierte. Killua während der Jägerprüfung, wenn auch viel weniger. Trotz des gegenseitigen Nutzens ihrer Beziehung glaubte Illumi immer, dass einer von ihnen das andere töten würde. Er nahm daher an, einen Vertrag mit Hisoka mit der Bedingung auszuschließen, dass Illumi seine Belohnung erhält, wenn der Zauberer getötet wird. Der Attentäter bezieht sich kryptisch als "Verlobungsring" und "Ehevereinbarung". Illumi verpflichtet sich jedes Mal, wenn er seine Fähigkeiten nutzt, beiläufig Massenmord und opfert das Leben unschuldiger Menschen in der überwiegenden Zeit.

Muzan is cold-hearted, ruthless, intimidating, and exceptionally intelligent. He sees no value in any humans he has encountered and shows little value in his own subordinates. Rarely ever visibly upset or happy, he appears completely monotone and detached on most occasions, even when he callously murders his own subordinates. The only times he ever shows emotion are when his vision of perfection is moving forward or when he has subordinates completely submit to his will. Initially, his expressions would only change slightly and only bear a slight shift from his usual calm attitude and his tone of voice tends to be consistent at nearly all times, accentuating his monotonous demeanor. His cruel and imposing nature has gained him the great admiration and fear of many demons. After Hantengu informs him of Nezuko Kamado's survival of sunlight, Muzan reveals a side that is in stark contrast to his perpetual composed disposition, as he is shown to be ecstatic at the prospect of absorbing her to finally gain the immunity to sunlight himself. In addition, he also shows himself to be extremely arrogant and prideful, first seen when he mockingly asked a platoon of soldiers sent to kill him if they were referring to him. His boastful side is also shown when he gloats to Kagaya about never facing any divine retribution for his millennia of murders. Furthermore, he is shown to have a sadistically cruel side to him, first shown when he reminds Tamayo on how she murdered and ate her family following her transformation, gleefully smiling as she wells up tears and further reminding her that she killed several people as well, rhetorically asking if he imagined that . In addition when Muzan has Nakime summon the Demon Slayers Corps inside the Infinity Castle, he sadistically boasts to Tanjiro that he will murder the entirety of its members that night, and when he responds with a vow to hunt him down, Muzan boldly dares the Demon Slayer to follow up on his threat if he can. It is heavily implied that after his encounter with Yoriichi Tsugikuni, Muzan's more vicious and overconfident personality was stifled by the sheer terror brought upon him by the Demon Slayer that nearly killed him, only resurfacing after learning of Nezuko's ability and realizing a new chance to complete his ultimate goal is now in his grasp. His inflated ego and delusional sense of self-worth are so large, he cannot stand being mocked or corrected in any fashion, believing that others only exist to serve him. This also means he rarely ever takes any opponent or threat seriously. He brutally killed a drunk man simply for being rude to him and killed the man's brother and a female companion when they had done nothing, all while proclaiming of his own perfection and superiority over them, displaying his shrewd pettiness as he won't settle for any mockery and will do anything he pleases until the humiliation is remedied. This event also hints that Muzan has unpleasant memories of his weaker, human past, and is very self-conscious of his unnaturally sickly appearance, immediately following his own rhetorical questioning with a lengthy denial that he is unhealthy, sick and much less on the verge of death, in all likelihood a bitter reminder that he is still imperfect. When he confronts Kagaya Ubuyashiki, the man responded to Muzan in a tone of pity and sadness for the life he had led. However, Muzan only interpreted his words as insults and threats, which further accentuates his hatred for humanity a

Zestial speaks in an archaic dialect redolent of early modern English. He has a very sophisticated way of speaking, and often keeps his temper rather than get easily frustrated, as the case when Velvette mocks him. However, despite his overall demeanor, he can be slightly petty, loudly sipping his tea to cut Velvette off mid-sentence before opposing her proposal to fight back against the Exorcists.

His reputation is such that demons other than his fellow Overlords are terrified of him, hiding or cowering whenever he passes by. The sight of him causes one civilian to set himself on fire out of fear.

Befitting his advanced age, Zestial is extremely patient and cautious, telling Velvette that they shouldn't take immediate action in spite of being given proof that Exorcists can be killed out of fear of the potential repercussions.

He is also shown to be compassionate to those with which he is close, sensing Carmilla's tension after an Overlord meeting and offering her an ear upon which to vent her concerns.
