Chrome Dokuro is a petite and slender girl, often described as cute and sweet by characters such as Mukuro Rokudo, Belphegor, Levi A Than, and Julie Kato. When she transfers to Namimori Middle School, she attracts the attention of many male classmates, further highlighting her delicate and charming appearance.

She has short purple hair, styled in a pineapple-like shape, a distinctive feature she shares with Mukuro, possibly as a sign of admiration or influence. Her large violet eyes match the color of her hair, though her right eye is permanently covered by an eyepatch. This eyepatch features a chrome-colored skull, concealing the injury she sustained in a car accident, which led to Mukuro replacing her lost eye and damaged organs with illusions. In the future timeline, Chrome is sometimes seen wearing a normal eyepatch instead of her signature skull-design one.

For clothing, Chrome is most commonly seen wearing the green Kokuyo Middle School uniform, similar to the rest of the Kokuyo Junior High Gang. Her uniform consists of a long-sleeved, sturdy jacket with a slightly raised collar and two vertical rows of buttons, totaling eight in number. She pairs this with a short pleated skirt secured by a thick dark belt featuring a skull-like design. Additionally, Chrome has been seen wearing the Simon Famiglia uniform as well as the Namimori Middle School uniform on occasion.

Regardless of her outfit, Chrome is often seen carrying a bag where she stores her collapsible trident, her primary weapon. A cover illustration depicting both Chrome and her younger self, Nagi, suggests that before her accident, she wore a sailor uniform, implying she previously attended a regular public school.

When appearing within an illusionary world, Chrome’s hair is longer, with her bangs covering her lost right eye, and she is dressed in a simple white gown. This illusionary form closely resembles Nagi before her accident, except for the addition of her covered right eye.

In the future timeline, Chrome undergoes slight changes in her appearance. She retains her skull eyepatch but allows her hair to grow longer, with her bangs shortened and positioned to the right. By this time, she abandons her “pineapple” hairstyle, opting for a more mature and natural look. Interestingly, her hairstyle inconsistencies are noticeable throughout the series while chapter 214’s cover illustration shows her retaining her signature pineapple hair, chapter 282 and episode 203 of the anime depict her without it, with a more refined look.

Her future attire reflects a simple yet stylish preference, consisting of a purple shirt, dark indigo skirt, and a violet jacket, indicating a shift towards a more casual and contemporary fashion sense.

Chrome Dokuro’s personality is deeply shaped by her tragic past as Nagi, a girl who suffered neglect and isolation before Mukuro saved her life. As a result, she struggles to open up to others, except for Mukuro, whom she reveres as her savior. Her attachment to him is profound, and she prioritizes his interests and relationships above her own. If Mukuro deems someone important or worthy of attention, Chrome instinctively considers them precious as well, regardless of her own personal interactions with them. While this might appear as obsession, it stems more from her deep gratitude and admiration for the only person who ever cared for her.

Her difficult upbringing has left lasting scars, affecting her social behavior and self-esteem. Even when shown kindness by others, Chrome struggles to accept it, having become accustomed to mistreatment. Rather than seeking out friendly company, she instinctively gravitates toward Ken and Chikusa, despite their rough and unkind treatment of her. This behavior suggests a deep-seated belief that she does not deserve kindness, leading her to cling to the familiar, even if it is unpleasant.

Chrome’s low self-worth prevents her from standing up for herself. She never speaks out or fights back when insulted, instead accepting mistreatment with quiet resignation. Even physical harm does not faze her, as seen in her calm demeanor when Ken or M.M. mistreat her. When Tsunayoshi Sawada seeks her out for conversation, she initially listens from behind a partially opened door, but withdraws entirely when Gokudera and Yamamoto arrive, indicating her extreme discomfort in group interactions. While she has specific individuals she feels more comfortable around, she remains shy even when treated kindly, as social interaction is foreign to her.

The concept of unconditional acceptance is completely alien to Chrome, making her extremely confused and hesitant when others treat her with genuine care. This is evident in her initial avoidance of Kyoko, Haru, and I-Pin, despite their friendly and welcoming attitudes. Bianchi observes that while kindness comes naturally to them, Chrome experiences it as a form of culture shock, illustrating just how foreign warmth and companionship feel to her.

Despite her timidity, Chrome possesses a strong will, especially in battle. She does not shy away from combat and is willing to risk her life for victory. However, her lack of confidence and dependence on Mukuro initially hinder her potential. While she harbors a desire to grow stronger, she often relies on Mukuro’s intervention instead of believing in her own abilities.

Over time, however, Chrome begins to change. As she gradually absorbs the kindness shown by her new friends, she learns to make decisions independently, relying less on Mukuro. When Mukuro is freed from prison, Chrome does not simply return to being his dependent follower; instead, she becomes determined to grow stronger on her own terms. No longer content with merely being a vessel for Mukuro, she resolves to protect those she cares about with her own strength, forging her own path as the Tenth Generation Mist Guardian of the Vongola Famiglia.

Chrome Dokuro is a skilled illusionist and close-combat fighter, wielding both mind-affecting illusions and a versatile trident to battle her enemies. Her abilities are recognized by some of the most powerful figures in the Vongola Famiglia, including Mukuro Rokudo, Reborn, and Mammon, making her a formidable Mist Guardian.

Illusions and Combat Skills
Chrome’s primary strength lies in illusionary combat, using her abilities to deceive and manipulate enemies. Her illusions can affect multiple targets simultaneously, creating an advantage in battle by confusing opponents and forcing them to question reality. If a target believes an illusion is real, the effects manifest physically, such as molten lava bursting from the ground, which becomes genuinely harmful if the victim perceives it as real.

Mammon, an expert illusionist, acknowledges that if they had believed in Chrome’s illusions for even a second, they would have been completely overwhelmed. This highlights Chrome’s advanced proficiency, as only a true master of illusions can distinguish her deceptions from reality.

Her tactical use of illusions extends beyond deception, she is able to create multiple simultaneous attacks, forcing her opponent to hesitate. This strategy traps enemies in a dilemma, as they must determine which attack is real and which is an illusion, often leading to them making fatal mistakes. Chrome is also capable of sensing illusions cast by others, as seen in her ability to detect Genkishi and Torikabuto’s illusions, even without using her Vongola Box Weapon.

In close combat, Chrome wields a trident, a weapon that allows her to keep opponents at a distance while striking with precision. She demonstrates proficiency in trident combat, effectively defending herself and utilizing its reach to compensate for her smaller stature.

Growth and Development
Initially, Chrome’s dependence on Mukuro hindered her individual growth as a fighter. She relied on his support and illusions in battle, making her vulnerable without him. However, as she gradually absorbs the kindness and encouragement from her new allies, she begins to develop her own strength and independence.

Reborn once speculated that if Chrome could discover her own fighting style, she might surpass her reliance on Mukuro and become even stronger. This prophecy proves true when she eventually learns to sustain herself without Mukuro’s influence, marking her transformation from a dependent vessel to a fully realized Mist Guardian.

Perhaps Chrome’s most significant milestone is her ability to generate her own organs, which were previously sustained by Mukuro’s illusions. By creating illusionary organs that function independently, Chrome ensures that her survival is no longer dependent on another person’s power. This breakthrough is not only a testament to her growing strength as an illusionist but also a powerful metaphor for her newfound independence.

Trident
Chrome wields a collapsible trident, similar to Mukuro’s, which she can store in a small bag by retracting its poles and handle. This trident was originally created by Mukuro’s illusions, but later, Chrome constructs her own version, which features a single spike instead of three, making it resemble a spear.

Vongola Mist Ring
Chrome wins this S-rank ring during the Mist Ring Battle, officially becoming the Tenth Generation Mist Guardian. She shares the ring with Mukuro, usually wearing it while he is imprisoned. The Mist Ring allows Chrome to generate Mist Dying Will Flames, which she uses for her signature Real Illusions.

In the future timeline, the Vongola Rings were destroyed by Tsuna, but Chrome later retrieves her Mist Ring through the Ten-Year Bazooka, ensuring that she can still wield its power. Eventually, the First Vongola Boss recognizes Chrome and the other Guardians as the rightful heirs, granting them the true forms of the Vongola Rings.

Gufo della Nebbia (Mist Owl)
Chrome acquires this Mist Owl Box Weapon during her battle with Glo Xinia, as it was inhabited by Mukuro at the time. Originally a Rain Box Weapon, the owl transforms into a Mist Box Weapon when Chrome accepts it.

Gufo di Nebbia ver. Vongola
The Vongola Box evolution of Chrome’s Mist Owl, now equipped with armor padding on its wings. In Cambio Forma, the owl transforms into Demon Spade’s Devil Lens, a powerful tool that allows Chrome to see through any illusion, making her resistant to deception-based attacks.

Animal Ring
At the end of the Future Arc, the Vongola Boxes were not allowed to be taken back to the past. However, with Verde’s assistance, the Vongola Boxes were converted into Animal Rings, allowing Chrome to retain her Mist Owl’s abilities even after returning to the present.

Earring of the Mist Version X
An upgraded form of the Mist Vongola Ring, Chrome initially obtains it in its Ore form. When Mukuro temporarily possesses her to activate it, the earrings transform, granting her new abilities. However, after Mukuro is freed, the earrings are returned to him, meaning Chrome no longer possesses them.

Dokuro (髑髏) means “skull” or “cranium,” reinforcing her gothic and mysterious aura, as well as her connection to Mukuro (which means “corpse”).

Nagi (凪) means “calm” or “lull,” symbolizing her reserved and quiet personality, contrasting with Mukuro’s more dominant and chaotic nature.

Her Japanese rōmaji name, Kurōmu Dokuro, is an anagram of Mukuro Rokudō, further emphasizing their deep connection and intertwined fates.
