Puniru

Puniru appears mostly as a cute, young girl around the same age as Kotaro.

Her body is made of polyvinyl alcohol glue and borax, making her look solid but actually closer to liquid.

She can change her hair, outfit, and even her whole body shape at will.

Puniru’s default look hides her ears with hair, as she finds them "not so cute."

Her original form was like a penguin, but she changed to look like a human girl to be cuter for Kotaro.

When transforming, Puniru can become anything, like an idol, a little kid, a cheerleader, a trophy, or even a gross lump if she feels down.

If she bumps into things or hugs someone, she can get sticky and her body may splatter.

Puniru is very cheerful, energetic, and loves to show off how cute she is.

She always refers to herself as "boku" and speaks in polite language, but calls everyone by their first names, even adults.

She is a total narcissist, always confident that she’s adorable.

She dreams big: Puniru wants to be the world’s most beloved character, open an amusement park named "Puniru Land," travel to space, and become the face of "kawaii."

Puniru doesn’t understand human ideas about gender or romance. She sees her girly form as just one of many cute shapes.

She thinks of humans as limited because they can’t freely change their bodies.

She still has the mind of a seven-year-old, so her knowledge is limited and she can be naive.

Puniru was created when Kotaro, as a child, wished for a cute friend who would understand his love for adorable things.

He drew a picture of his ideal friend and accidentally mixed it into his homemade slime, which then came to life as Puniru.

Puniru’s spirit was awakened by a goddess who told her that her main purpose is to help and support Kotaro with his worries.

However, for more than seven years, Puniru hadn’t been able to fully solve Kotaro’s troubles.

Puniru can freely shape-shift by adding things like borax and glue, along with other materials, to her body.

Her imagination is her limit—she can imitate idols, become a boy or a girl, take animal shapes, or transform into objects.

She can slip through pipes, disappear into drinks, or drip from the ceiling.

Pieces of her body can split off, move on their own, and rejoin later without harm.

She has little physical toughness and will fall apart under pressure, but can re-form easily.

She can even absorb people inside her body, like swallowing up Kotaro for fun.

Puniru is very close to Kotaro Kawaii, the boy who created her.

She often hugs him, sneaks into his bed, and does her best to impress him with her cuteness.

Puniru cares a lot about Kotaro’s opinion of her and wants him to think she’s as cute as when they first met.

She doesn’t have romantic feelings for anyone, not even Kotaro, since she doesn’t understand romance.

She has no concept of rivals in love, but she is a little afraid of Mami Kirara’s overwhelming motherly vibe.

Puniru is called "Puniru-chan" by everyone and treated as a girl, even though she is genderless.

Her birthday is February 29.

She turned 8 years old in episode 59.

She loves cream soda and sweet snacks.

Puniru’s dream is to create "Puniru Land," sell her own merchandise, travel to space, and collect 1,000,000 yen from everyone.

She usually sleeps in a special container labeled "Slime."

Puniru was inspired by Yoshi from "Super Mario-kun," being an assertive, polite character.

She often says, "It’s the cute me!"

Her creator, Kotaro, was bullied for liking cute things as a boy, and Puniru was made as his wish for a cute friend.

How Puniru Was Born

When Kotaro Kawaii was a small child, he was bullied because he liked cute things even though he was a boy.

He wished for a friend who would understand him and drew a picture of his ideal companion.

Accidentally, he put the drawing into the slime he was making, and that slime became Puniru.

Puniru’s Purpose

On her birthday, February 29, a goddess appeared to Puniru and said she was given life to help Kotaro and solve his problems.

The goddess was almost about to take Puniru’s soul away because she hadn’t fixed Kotaro’s troubles after 7 years.

Kotaro rushed to protect Puniru, so the goddess agreed to let them be together and watch over them for now.

Transformations and Adventures

Puniru can transform into many different forms using slime ingredients and random craft materials.

She has become a pop star, a school child, a boy prince, a car, a fairy, a dragon, and many more.

Sometimes, changes in her mood or accidents, like eating the wrong thing, make her transform oddly, such as turning into a messy blob.

Puniru gets into funny and wild situations, often causing trouble or confusion for Kotaro and her friends, but always bounces back with happiness.

Life with Kotaro

Puniru lives with Kotaro and is always by his side.

She helps him with personal problems, cheers him up, and sometimes creates chaos with her free transformations.

She works hard to get Kotaro to call her cute, just like he did when he was little.

Even though she is called a girl and acts cute, to her being "cute" is just like choosing an adorable shape, not a reflection of being a girl.

Puniru doesn’t eat regular food but loves cream soda and sweets.

She can also eat things like paper cakes, clay, or even drawings of food.

Her sense of "cute" is very different from humans—she thinks things like sandals or animal shapes are just as cute as being a girl.

She has no worries about showing her body, since she is just made of slime.

Puniru’s spirit and memories stay even if she splits into pieces, and every piece can act on its own.

She treats clothes and bodies as just different "skins" or forms she can wear or change.
