Numbuh 3

Kuki Sanban, also known as Numbuh 3, is one of the main characters from the Codename: Kids Next Door series.

The team's medic, and the most feminine of the kids, a happy-go-lucky girl who loves Rainbow Monkeys. She seems to have a lot of admirers, but her heart obviously belongs to a certain Aussie.

Appearance
Kuki is a girl of Japanese descent. Her usual outfit is an over-sized green shirt, black leggings, green socks, and black and white converse shoes. She has long straight black hair with bangs. She has more alternative costumes than any other character in the show.

Personality
Numbuh 3 is described as the "Diversionary Tactics Expert," and is the nurse of the medical lab and the primary caretaker of hamsters in Sector V. She has a very short attention span, but is long on charm, speaking in a slight Asian accent, and often alludes to her Japanese heritage. She is optimistic, clueless, kind, patient, gentle, and arguably smarter than her teammate, Numbuh 4, with whom she harbors a mutual crush seen throughout the show, though it is less obvious. She loves Rainbow Monkeys, which she collects, fantasizes about, and has extensive knowledge about. Due to her great love for Rainbow Monkeys, she will often irrationally defend them, occasionally allowing her aggressive side to show (generally accompanied by her face turning red, teeth and ears becoming pointed and eyes flaming, resembling an oni, demons from Japanese mythology).

Abilities
In battle, she specializes in diversionary tactics. Not in the show proper, but in the Cartoon Network game Rainbow Monkey Rundown, she fights King Sandy's minions with a yo-yo.

Trivia

 * Her most prized characteristic, according to Operation: C.A.R.A.M.E.L., is her cheerfulness, which is "almost too sweet."
 * Her favourite type of Rainbow Monkey is an orange one, referencing her crush on Wallabee, specifically his orange hoodie.
 * Her favourite snack is popcorn, as shown in No P in the Ool, Operation: S.L.U.M.B.E.R. and Operation: P.L.A.N.E.T.
 * Her codename is linked to her last name "Sanban", which is Japanese for "Number 3"; san means three and ban means number.
 * Her stuffed animals have the number 3 painted on them.
 * She is the 23rd person to steal Death's scythe, even though she technically received it through legal means.
 * The only time she got to lead a mission was Operation: F.A.S.T.-F.O.O.D..
 * She was temporarily Sector V's leader in Operation: F.E.R.A.L..
 * It is revealed that she is not as 'air-headed' as she leads everyone to believe, as seen in Operation: I.N.T.E.R.V.I.E.W.S., when Numbuh 1 is leaving and she asks him what they are doing the next day, to which he replies that he won't be there, and she says, "Oh, I know you're leaving, silly. What do you think I am, an airhead or something?"
 * It is hinted that Numbuh 3 may be the one to create the acronyms for the missions and 2x4 tech as seen in The Grim Adventures of the KND, when the M.A.N.D.R.O.B.O.T. has a stupid acronym and Mandy asks Numbuh 3, "What kind of acronym is that?!", to which she replies, "Well, if you weren't in such a rush, I could've come up with a better one!"
 * There is a running joke with Numbuh 3 where whenever she's ejected from Hippy-Hop, her parachute always comes out after she's already hit the ground.
 * Kuki is the only member of Sector V to have never called Numbuh 1 "Nigie".
 * Her given name is Japanese for "stem". It can also be written as (kūki), which means "air", and reflects her carefree personality.
 * One thing that she is afraid is that all the rainbow monkey's in the world would disappear.
