Mr. KK is one of the characters from Pop'n Music 5.


One of the cleaning staff who cleans the Nishi-Shinjuku buildings every day.
His other side is apparently a sniper who earned the nickname "scavenger". Is it a secret?

Mr. KK is a Police Officer, who now works undercover. He has a strong military background. Even though he is an introvert and practical joker at times, he has a very friendly personality about him.

He has a second job being a janitor who cleans office buildings, where he works with his boss at Tokyo's Nishi-Shinjuku Plumbing.

He is sometimes seen with Belle, after he found her pet cat, where it seems to dislike him.

Character Information

See Mr. KK/Character Information.



Mr. KK appears as a tall man with short, brown hair, a shaved beard, and dark brown eyes. He wears a periwinkle blue suit along with his hat and pink-red headphones. He dons a pair of black shoes with a skull icon in each sole. Additionally, he wields a brown mop for duties. His debut garments appear again in his FEVER! animation in Pop'n 20 fantasia.

In his 2P palette, he has strawberry blond hair and his outfit becomes all black with hot pink accessories and shoes. His headphones remain the same while his mop handle is red.

His URA color from Pop'n Music 11 makes his hair red and his outfit lime green with black shoes and blue headphones, and his mop handle becomes dark lavender.


Mr. KK wears a dark sea green suit shirt along with gray striped pants, black socks, and brown shoes. He keeps his blue hat and red headphones and has his hair tied back. His original palette is recycled in On top of the world from Pop'n Music éclale.

In his 2P palette his hair is light blond and his eyes are a lighter brown. His suit top is blue and worn with a teal shirt, and his pants are olive green. His shoes and hat are a mahogany color and his headphones are dark orange.

Mr. KK has taken off his blue janitor suit except for the blue pants. His white shirt is shown for the first time and the black shoes remain identical. Mr. KK carries a water backpack connected to his water gun. His hat becomes a more violet hue and he wears yellow-pink headphones.

Once again his 2P colors give him blond hair and light brown eyes. His outfit is mainly black except for his navy blue shirt and purple headphones.

Urban Rock

Mr. KK wears a long, dark green jacket with fur trim along the hood over his dark gray pants and black shoes. His hat is also dark gray and worn over orange headphones.

Mr. KK's 2P palette shows him with blond hair and light brown eyes. His coat becomes sky blue while his pants, hat, and fur trim are brown. His headphones turn light blue.

Other Character Comments

Pop'n Music 10:
The family business is secret. Super secret. From cleaning buildings to table waiting and looking for a cat,
Honey can rely on me to do anything (but only cute girls can ask)
Pop'n Music 15 ADVENTURE:
This time he works for a living to get safe water in the water department?
...huh, a water gun, what kind of job??

Pop'n Music 20 fantasia:
Urban living is fast paced every day. Once in a while you want to relax and some days just speed walk.
...but, despite what I say it seems like I don't?
