Kuromi: Unraveling the Charm of Sanrio's Mischievous Character

by Nana Young

Underneath the tough appearance of Kuromi lies a soft, girly personality that few people get to see. Thankfully, we’re about to peel back all the layers and reveal the true nature of one of Sanri’s most fascinating characters.

Introduction to Kuromi: Sanrio's Enigmatic Character 


From the My Melody universe come the enigmatic Kuromi and her antics. Kuromi is a cartoon character created in 2005 by Sanrio, a Japanese entertainment company. She is a female rabbit that fills the role of the antagonist in the My Melody universe.

Kuromi is actually a doppelganger of My Melody. The two rabbit characters look identical, except for some differences in their tails and attire. Kuromi is a white female rabbit with imp-like features. She has a black devil's tail that’s shaped like an arrow at the tip.

Kuromi always wears a signature black jester's hat inscribed with a pink skull that changes expressions to match Kuromi’s mood. When you translate her name from Japanese to English, you’ll find that it means “black beauty.” She was born on October 31, which happens to be Halloween. This is fitting, as Kuromi was originally created to be the mischievous and dark antagonist in the My Melody universe and beyond.

In public, Kuromi loves to act like an unrepentant tomboy, but she’s secretly as girly as they come and tends to crush on cute male characters. She also loves to cook and read romance novels. Her overall personality can generally be described as naughty, angry, mischievous, and enigmatic.

Kuromi flies around on her sidekick tapir, called Baku. Family members also appear at different points in the anime. Her mother, father, and sister (Romina) all bear striking resemblances to her.

Since her debut in 2005, Kuromi has become hugely popular among young people all over the world, especially those in the punk, biker, and goth communities. She is a major Sanrio character and was voted the third most popular on the 2023 Sanrio Character Ranking, surpassing My Melody. The company fully recognizes Kuromi’s popularity and has created several forms of media, merchandise, and themed events based on the character.

The Origins of Kuromi: Exploring Her Backstory

The initial character plans for Kuromi were quite different from how things turned out. Yuko Yamaguchi, one of Sanrio’s designers, created the Kuromi character in 2005. She was only intended to be the main villain in the anime series Onegai My Melody. However, the white rabbit was so cute that viewers couldn’t hate her for too long, and many took a liking to the character because of her fierce nature. Kuromi’s reception after the release of the series caused the executives at Sanrio to turn her into an official character, eventually green-lighting her own animated shorts spin-off on YouTube titled Kuromi’s Pretty Journey.

According to the storyline of Onegai My Melody, Kuromi is an escaped prisoner from My Melody’s hometown, a forest called Mari Land. She exhibited extreme hatred for My Melody, accusing the latter of ruining her life and wronging her 6,324 times. It’s implied that My Melody and Kuromi were once friends. That was the beginning of several unsuccessful attempts by Kuromi to get back at My Melody. The two will eventually go back to being friends in Onegai My Melody: Yu and Ai.

Thanks to the creative minds at Sanrio, Kuromi appears in Hello Kitty and Friends: Supercute Adventures with most of her personality intact. She still doesn't like My Melody, but her hatred is not as strong. She remains her usual naughty self, but is closer to an anti-hero than an outright villain.

Kuromi's Personality Traits: A Playful Mixture of Sweet and Spicy

Kuromi Personality

Part of what makes a character like Kuromi so popular is having a deep and interesting personality. In this section, we’ll explore her key personality traits and provide a better understanding of how the character behaves. Check them out!

  • Mischievousness: It’s no secret that Kuromi loves causing mayhem wherever she goes. In fact, it’s her most prominent trait, as she makes no effort to conceal it. One of her worst pranks involves corrupting dreams with a magical item called “melody key.”

  • Disregard for laws: Kuromi’s rebellious nature often places her on the wrong side of the law. The crimes she has committed include theft, vandalism, fraud, assault, and prison break.

  • Tomboy: She displays a masculine toughness that classifies her as a tomboy, at least in public.

  • Secret girliness: When no one is looking, Kuromi displays her inherent girliness. She cooks, reads romance novels, keeps a diary, and daydreams about her crushes, including Keiichi Hiiragi.

  • Love for black: Her favorite color is black, obviously.

  • Love for diary keeping: Kuromi keeps a detailed diary, which reveals a side of her character that wants to express her feelings. In the midst of all the chaos in her life, Kuromi still has a contemplative and reflective side.

  • Leadership: She is the leader of a biker gang, made up of 4 other girls (Konmi, Nyanmi, Wanmi, and Chumi), a feat that requires tenacity and bravery.

Kuromi's Appearance: Dark and Cute Design Details

From her looks, you can clearly see how Kuromi was designed to contrast with My Melody while maintaining her own identity. She is a white rabbit, just like My Melody but she has a black devil tail, which is common in imps or imp-like creatures.

Kuromi also adds accessories to her signature dark color palette by wearing a black jester hat. This hat is a clear nod to her role as a mischievous prankster. It also has the symbol of a skull inscribed on it. There must be something magical about this skull because its eyes can change to match those of Kuromi. Hence, they appear to share the same emotions.

Her character design also includes pink colors, adding a level of cuteness to all of those black colors. In certain scenes, Kuromi wears pink skull cherries on one ear.

Overall, Kuromi’s design appears similar to cute yet edgy design elements in cartoons in the 1920s and 1930s. Yet, she doesn’t look one bit out of place in the modern anime scene.
