Kureto Hiiragi Husbando

Arrogant and powerful, Kureto doesn't tolerate any disrespect from lower-rank families. He is manipulative, ruthless, and treacherous (Shinoa describes him as a "monster"), and will not hesitate to abandon his comrades if he no longer finds them useful. In fact, he finds that being able to abandon one's own friends as a strength. He expects everyone to submit to him with absolute loyalty, and would even go so far as to threaten them to do his work. As such, Kureto is very confident with himself, his plans and his actions. Kureto has an ambition of wiping out every vampire on the planet and intends to rule the world, stating that he will turn it into a "vampire-free paradise." He plans to gather every surviving country and unite them as one, making Japan the center of all nations (i.e. world domination). Guren comments this as "something a kid would make up." Despite his harsh personality, he possesses a sense of self-righteousness and sees anyone who is willing to sacrifice others for pure greed and with no goal as evil and he does firmly believe that a leader must be responsible for their followers. It is due to this that he shows nothing but disgust at his brother, seeing his incompetence and cowardice as being useless and idiotic, along with also coldly rebuking father, openly noting that it was the duty of a king to keep their subjects save. Kureto's utilitarianism convinces him that if sacrificing the minority will be able to save a larger amount of people, then he'll gladly dirty his hands with the blood of innocent people. This was shown when although he remorselessly sacrificed the soldiers of the Imperial Demon army, he sincerely believed that they died heroically as it was thanks to their sacrifice that he was able to revive the Seraph. Kureto even seems to consider his life as not being worth that of the world's destruction, as shown by how he told Guren that if he can't be saved, then he is allowed to kill him. This is also shown in the light novels, where he is shown to be willing to give his life to take out Mahiru as he believes her to be a monster and if he was saving humanity from her, his life would be a small price to pay. Despite his unsympathetic and serious nature, Kureto shows that he can overcome personal suspicions and show kindness to individuals he deems worthy, treating his loyal subordinates well. This even extends to Guren Ichinose, who despite being initially suspicious of him as he was a potential spy, he comes to value him as his henchmen after seeing him do his orders, with Guren even becoming his right-hand man and Kureto admitting he trusts him. Even before coming to trust him, Kureto already gifted him an extremely powerful new sword, a Hīragi family heirloom that was strengthened through the hatred and fear of the people it had slew before and eventually starts to keep an eye on him in the light novels and even shows him surprising sympathy at times, which typically bewilders Guren. He firsts keeps his end of the deal with Guren regarding him gaining more information on the Cursed Gear Experiment in exchange for ensuring that the Order of Imperial Moon be spared from being deemed traitors and him trying to save Guren, notably not killing him despite it being the easiest thing to do, which baffled Shinya over his decision to save Guren, and proceeding to make the Order of Imperial Moon's experiment on the Cursed Gear look as if it was his orders, allowing the members to be spared and Sakae's execution postponed for two days. Kureto also allows Sakae to call Guren and chat and then gives Guren the opportunity to chase after Mahiru by turning himself into a victim and letting Guren steal his helicopter. Even though Guren did not fulfill his goal of killing Mahiru by the deadline, Kureto was still satisfied by the results that Guren bought nevertheless and was the only one who voted against the execution of Sakae Ichinose, showing that as harsh and ruthless as he is, his standards isn't as high as his father. After Sakae was ultimately executed, Kureto, although coldly telling Guren about the fact that the execution was complete, showed some pity and kindness towards him by allowing him to be consoled by his friends and even outright showing pity when he joked about wanting to be thanked by Guren; when Guren did thank him for opposing Sakae's execution, Kureto did not gloat on his superior position but just said it was natural and left. He also looked utterly unamused after Guren was badly beaten by Tenri, laughing without humor only when Guren challenged him to and offers him a handkerchief and a drive home, being unfazed when Guren calls him weak. Along with that, he decided to spare Guren despite having overwhelmed him and being ordered by his father to do so and revealed Mahiru's locations, entrusting to him the responsibility of stopping Mahiru. The random acts of kindness he sometimes exhibits to his subordinates includes giving Aoi a gentle and encouraging smile when her leg was sniped off by an assassin sent by Tenri, and helping Aoi reattach her leg, going as far as bloodying his hands in the process.
