Kuyou

Kuyou is a major antagonist in the anime/manga series ''Rosario+Vampire. ''He is the leader of the Public Safety Commission until his defeat at the hands of Tsukune Aono, Moka Akashiya and their friends, after which he moves on and becomes a member of Fairy Tale. He is a kitsune, an S-Class species of monster who are amongst one of the most powerful of all Yōkai who live in Japan, and they have even known to be worshipped as divine beings.

He is voiced by Shuichi Ikeda in the Japanese version of the anime and Jason Douglas in the English version, the latter of whom also voices Beerus.

Personality
Kuyou's defining traits are as follows; misanthropy, hypocrisy, arrogance and delusions of grandeur. He enforces the rules of the Public Safety Commission with a tyrannical and sadistic iron fist, going so far as to state if someone goes against him, they are against the school. He sees nothing wrong with what he and his group do, believing it all to be in the name of peace. While none of the student police force are particularly nice people, Kuyou is without a doubt the worst of them all. Possessed with a strong lust for power and relentless sadism, he is a tremendously cruel individual who takes great satisfaction in the pain of others and thrives on the fear and submission his actions receive. He is extremely confident in his abilities, as shown by his utter shock at Yukari and Ruby hurting him with a combined spell. He also possesses a fearsome temper and will quickly fly into a rage with little provocation. He has a deep hatred and distaste for humans, believing they and monsters will always be enemies and that any friendship between the two exists only in fairy tales.

However, it's only when Kuyou fights Moka that it's made clear just how completely hypocritical he is; he calls out humans for lying, cheating, stealing, betraying and hurting other living things without a second thought, as though completely oblivious to the fact that he's done all those same things himself. When Moka calls him on his criminal activities and hypocrisy, he is thoroughly outraged and tells her to shut up. This reflects that he's got a problem with "injustice" only when it doesn't suit his needs.

Kuyō has a deep hatred for Tsukune, born from his defeat at the latter's hands. He does not think highly of Tsukune, believing he's just a weakling who has to hide behind the women around him and is insulted by the very idea of having lost to such a man. When Tsukune overcame his fear of Kuyō and fought him seriously the latter was further enraged and suffered disbelief due to the difference in their powers, he went on to use his full power, bragging he could kill Tsukune and advance ever further, but suffered only further humiliation upon failing to defeat him a second time. During the moment of his second defeat rather than trying to understand how Tsukune defeated him, Kuyo instead just display disbelief at the thought of defeat from Tsukune despite it happening to him twice. Also after his second defeat, he proceeded to brag about the dimension designed to kill them thus showing that he is a sore loser.

Despite these faults of Kuyo, in the Rosario Vampire II chapter 67 Extra II, it's been shown that he has some honor towards his fellow monsters if they have his respect as he agreed to look after Kahlua when Miyabi revived her before going into battle against his enemies. He also shown concern towards Hokuto when the latter's hybrid blood deterioration left him completely unconscious and unable to wake up after his fight with Kiria despite being a former human whom he has a deep seated hatred towards. Also during his observation of Alucard's final battle against all of his enemies, Kuyo is shown to have solemn look towards the scenery and left with Kiria to rebuild Fairy Tale despite its tremendous loss which implies that Kuyo decided to learn from his loss against Tsukune rather try to attack the latter and his friends just after the battle in spite of their vulnerable state of just recovering from fighting against Alucard.
