Tsukasa Hiiragi is generally a sweet, naive, innocent and dimwitted person who never gets mad, similar to Miyuki. Her calm, girly, cheerful, and friendly personality heavily contrasts with that of her sister, Kagami, who is a Tsundere and takes on a much more harsh, tomboyish, and arrogant attitude.

A very silent girl (usually speaking in as few words as possible) who is very impassive, Minami is often mistaken for being cold, but she is very kind at heart. However, many jokes arise when her seemingly "perfect and sleek" appearance is contradicted, such as when Miyuki's mother notices Minami teaching Cherry how to stand on her hind legs by mimicking the position herself; Minami often blushes heavily and stares at the floor in response to such teasing. With her overall first-impressions, she tends to be mistaken as the "modern-day tsundere" type.

Kagami is the stereotypical Tsundere in the group. She's a bit egotistical, and somewhat weak in common household chores, such as cooking and cleaning, unlike her sister Tsukasa, who excels at cooking. She can be the straight and intolerant type. However, she is prone to become shy and lonely at times. Kagami is constantly attempting to hide the fact that she has a deep sense of attachment to her friends, especially Konata.

Akira's idol persona tends to be very energetic, and her chief form of greeting is "Hiya, Luckies!" ("Oha Lucky" or "Ohayou Lucky" in Japanese), and frequently ends each episode with "Bye-ni!/Bye-nee!". The cute persona, however, is a cover-up; in reality, whenever she is annoyed or feels that her career or popularity is threatened (usually both by her assistant, Minoru Shiraishi), she immediately breaks character. For example, when Minoru once called something she said lame, she grabbed him and yelled, "Did you say something?!" Akira's bright persona is instantaneously shed to reveal a deep voiced, violent, chain-smoking, selfish-cynic of a burnt-out entertainer on the brink of becoming a has-been. However, her talents are undeniable; she has been in the entertainment business since the age of three.

Miyuki Takara is a pretty, smart, and friendly girl, who can be outgoing despite her reserved nature.

Numbuh 86 speaks with a thick Irish accent and has a loud voice, especially when she yells which she does often especially for someone so rude. She is rude, ill-tempered, bossy, stubborn, hypocritical and mean, but is strongly loyal to the Kids Next Door. As mentioned above, she has a strong distaste in boys, most notably shown during her first appearance in Operation: F.U.G.I.T.I.V.E., where she essentially takes Numbuh 1, Numbuh 2, and Numbuh 4 out of a mission simply for being boys and instead readily listens to Numbuh 5 and Numbuh 3.

This depiction of Alucard is as cocky, arrogant, and egotistical as his original counterpart, but unlike the original, he is is sarcastic, rude, perverted, argumentative, and rebellious, often disrespecting or mocking his enemies in a very distasteful and vulgar fashion.

In fact, the only times where he obeys her orders are if he is either paid for it or if he can have genuine fun while doing it
