Himekawa is one of the side character delinquents of the Beelzebub Universe. After his first appearance, he never poses much of a threat to Oga and Beel aside from the occasional passing threat. Himekawa is a delinquent through and through, even going so far as to sport the typical rebellious pompadour associated with the subculture. However, all of this changes when Himekawa runs out of his specialized styling gel and is forced to let his hair hang loose.

Himekawa, with his hair down, becomes the school's heartthrob; attracting the attention of all his female peers. Himekawa is not oblivious to this either and uses his signature catchphrase ("I'm Himekawa, didn't you know?") to send his onlookers into a frenzy. Casting aside his typical delinquent demeanor, Himekawa flirts with his fans, helps a young girl from falling over, and agrees to requests to repeat his catchphrase. Himekawa lands at the bottom of this list as, when his hair is up, he gives off very little narcissistic energy. However, for the huge contrast between these two personality traits, he deserves a spot on this list.

Lust, as her name would suggest, is the embodiment of Father's lust and uses her beauty and flirtatious mannerisms to seduce those around her. In doing so, she strives to feed on their desires to not only increase her own power but to fulfill Father's wishes as well. Lust is a lot more sadistic than she is narcissistic but knows the extent of her beauty very well. She is able to lure weak-willed enemies into her spiderweb before finally going in for the kill.

Lust is portrayed as incredibly intelligent and tactical when using her charms to seduce people. She is seen throughout the series tricking people, making friends turn on each other to gain her affection, and expertly extracting information from tight-lipped enemies. Lust despises humans and their easily manipulated minds. As such, she feels no qualms in using them to further her gains and will use her beauty in order to do so.

After the Strawhats suffer their first major loss, Kuma sends the pirates to random places across the world. Where characters such as Zoro and Usopp are sent to perfect locations to assist with their training, Luffy is sent to a kingdom of women warriors under the rule of the snake princess herself, Boa Hancock. Boa's claim to fame as a shichibukai is that she is considered to be the most beautiful woman in the world. And, when we say everyone thinks this way, we are most definitely including Boa herself in that description!

Boa, upon first meeting Luffy, is stunned that he has no interest in her physical appearance. She is used to people of all genders falling at her feet upon first glancing at her and often uses her beauty to get what she wants or be forgiven for past mistakes. Luffy, however, rejects even a naked Boa and we see her fly into dramatic fits whenever Luffy talks down to her. As time progresses, Boa warms to Luffy and eventually falls in love with him (going so far as to propose on multiple occasions). What can we say; girls love bad boys.

Teruhashi is an angel with perfect looks, a perfect personality, perfect morals, and perfect grades. At least, that is what she constantly tells herself through her inner monologues. Teruhashi is not just your average narcissist, however. She goes above and beyond to prove that her beauty extends past her physical appearance and performs good deeds whenever she can to uphold her idol image.

Much like Boa Hancock, Teruhashi is thrown aback when Saiki Kusuo refuses to acknowledge her beauty with a patented "ofu". Teruhashi concocts crazy scenarios in her head as to why Saiki must not like her such as his feeling embarrassed to talk to her or him thinking she must be a mirage. However, as we've seen in the past, all of this negging from Saiki only pushes Teruhashi closer to him as she soon develops a crush on the pink-haired psychic. Teruhashi continues to act as perfectly as possible despite having a crush on the school weirdo (something damning for her image).

We've seen very little of Uzui so far in the sequel series of Kimetsu no Yaiba but, from the brief glimpses we've had of him, it's understandable why he tops this list. Uzui is the most glamorous Hashira and loves to adorn himself in trinkets and makeup to make himself as pretty as possible. This doesn't go unnoticed as Uzui attracts the attention of several women when trying to offload the crossdressing recruit Demon Slayers onto the various pleasure halls.

Uzui is well aware of the effect he has on women and uses this to get what he wants whenever possible. He is also very rude and obnoxious (at least thus far) when speaking with Tanjiro and the others. He pays little regard to other people's feelings (when trying to kidnap a young girl for his mission for example) and believes he has the right to do anything he wants due to his power and beauty.
