Early Life

She is born on September 30, 2002, in the city of Cryglen, Avalaera, Ventilus, as Caitlineia Malicha Pagonia Eurius. She is one of the daughters of a Ventilussian couple, with Cordelia as her twin sister. In the neighborhood, there stood Thunderous Tornado Castle. Her first childhood friend is Josh the Hedgehog, the great grandson of the 1st Lesser Deific Ventilus King. she often played outdoor games with him. However, three years later, she was chosen to be one of the slaves of a Pyronian tyrant. She was separated from her childhood friend. After a year of bondage, she fled from her evil master at night through her Pagonian Psychokinesis. She went back to Ventilus to return to her family. However, extensive use of her psychokinetic power dealt a strain to her body and collapsed near an orphanage.

She was never found by anyone, except a young Ventilussian nun. She seemed to be the owner of the orphanage.



During her childhood times, she had a mildly cheerful demeanor. She is a very close childhood friend of Josh the Hedgehog. She often played outdoor games with him. However, when she became a slave, she became emotionally detached, resulting to the complete loss of her cheerful bearing. She became a very quiet, bland, and mysterious individual.

Fortunately, this condition did not last long subsequent to their reunion. Her mild cheerfulness returned, and a boost of aesthetical value followed. She now valued elegance and modesty. She is even strict in terms of choosing clothes in her wardrobe for a specific occasion. Her complete silence became taciturnity. However, her mysteriousness remained. When she is with her husband at public, she does not display any form of romance of some sort. She only bonds with him as a couple in private circumstances and is not shy to do so, because she is also firm in her beliefs and ways to enjoy her marriage life.

As her real name itself implies purity, she is christened as the legendary "Platinum Heart", due to her high level of charisma and beauty. She can persuade an individual to return to his or her old deeds, which can benefit himself and others, even if they are within an inch of complete corruption. She can only do this efficiently if she is willing to do so. She is denominated as one of Layla's counterparts, because of their completely contradicting personalities. 


She may not look powerful, but her powers are as formidable as Layla the FoxSkunk, as cited in The New Organization Chapter 1: The Eggmen Assault. She possesses a wide variety of powers, which dubbed her as "one of Layla's coincidential antipodes", along with Patricia the Skunk

Ancient Aerokinesis

She rarely uses this type of magic, until Josh the Hedgehog X: Ancient Adventures/Episode 79, when she was unable to use Pagonian Cryokinesis because of the aura she released that created crimson snowflakes in Diablodia. Due to Josh's Ancient Rejuvenation, he was able to give her the path to master Ancient Aerokinesis. She can cast strong wind spells which usual aerokinetics are incapable of casting.

Pagonian Psychokinesis

Between the twin sisters, Yuki is the only one who has been taught about the arts of Pagonian Psychokinesis by their mother and is the only one who has mastered it at an early age of 500. Examples of Yuki's abilities involving Pagonian Psychokinesis are:
  • Shock Visions - She can create shock visions in her opponent's mind directly or indirectly. She can only do this on a single person, until Episode 79. In order to cast the spell indirectly, Yuki must make eye contact with her target and at the same time, cast the spell.
  • Telepathic Mode - She can turn invisible in this state. She can also communicate with other beings she is very familiar with, through the ability of telepathy.

Pagonian Cryokinesis

She was able to learn Pagonian Cryokinesis from her mother. However, she is unable to master these arts easily, unlike her twin sister, Shizuku the Hedgecat, who is a prodigial practitioner. Additionally, Shizuku remarked that her twin sister was able to release her full potential in using Pagonian Cryokinesis during the time when the crimson snowflakes fell from the sky, and it was yet stronger than her mightiest skill.

Rune of Immortality

  • Enhanced Regeneration - Due to her Rune of Immortality, her wounds heal faster than any mortal being, as shown in The New Organization Episode 2: wherein she recuperated earlier than Patricia.

Ancient Photokinesis

Yuki unwittingly possesses the lost arts of Ancient Photokinesis. It is presumed that her first time to use this magic is in Ancient Battle Chapter 3: Nightmare's Reign.


When she bestows her Rune of Immortality to a person with Special Psychomancy she bestowed upon that person, she dies. Also, when she is knocked out by a very powerful attack, she doesn't get any progress or she can't be awakened in this state, in order to regenerate. This state is known as Subcoma. Fortunately, she can't be attacked.

Josh the Hedgehog

Currently, she and Josh are married, as stated in the Primordial Codex of the Ancients. Before they were married, they were close childhood friends. They often played outdoor gamed together. Howver, since the tyrant arrived in tbeir hometown, their presence was severed, but their bonds remained. Josh swore to save her from the tyrant by negotiating with him in a peaceful manner.
