Ikuto Tsukuyomi

Ikuto Tsukuyomi is one of the main characters from the Shugo Chara anime and manga.

Ikuto is a teenage boy contracted by Easter to find the Embryo. He often helps Amu Hinamori even though he works for the Easter Company. Ikuto actually despises Easter and tries to wrench himself free from them by trying to find the Embryo to grant his own wish. By chapter 43, he had left Easter Company in search of his father. In the third season of the anime, he is already traveling the world to search for his father and therefore is absent from the series.

Appearance
Ikuto has blue hair and eyes. He is taller than Amu Hinamori and Tadase Hotori.

He wears a choker with a silver cross. He is most often seen in his black school uniform, but he has been seen in other black (or indigo) outfits.

Personality
Ikuto is enigmatic, aloof, stoic and a little naughty, much like an alley cat. He can also be sweet and kind. He likes teasing people, especially Amu and Tadase. Ikuto is selfless and protective, thus, he is willing to distance himself from those he cares in order to protect them and stop them from getting embroiled in his own troubles. This explains why he kept himself away from Utau after she allies with the Guardians. Another example of this is when he makes fun of Tadase so that he'd be hurt and make Amu hate him, so ultimately they [Amu and Tadase] would not meddle with his troubles with Easter (especially Amu).

Although Ikuto may seem to have a passive personality, he is quite perceptive and honest.

As for chapter 43, Amu states that Ikuto "loves music... and his dad".

Character Change
During a character change, Ikuto gains a pair of cat ears and a tail, and is bestowed with reflexes and moves that only come from a cat. He can also form virtual cat claws from his hands, created to form the attack Phantom Claw, something he cannot do during Character Transformation.

Character Transformations
Ikuto only has one standard transformation, and that is "Black Lynx". However, due to being manipulated by Easter's powers, he gains a new transformation, which he will most likely not be able to use anymore after the battle versus Easter ended.

Black Lynx
Ikuto can Character Transform with Yoru into Black Lynx. This represents his desire to be as free as a stray cat. Black Lynx first appears in Chapter 7 of the manga and Episode 13 of the anime, where he "saves" Amu from an X Egg only to break it.
 * Appearance: When transformed, Ikuto grows cat ears and a cat tail and wears a short navy top with long navy pants. He also wears a glove on his right hand with metal claws.


 * Abilities: Ikuto gains increased cat-like reflexes and senses. He can use his gloves' sharp claws to utilize an attack called Slash Claw

Death Rebel
A plan executed by Kazuomi Hoshina involved using Ikuto's X Egg energy influenced violin to control him. The result was Ikuto having been manipulated to become Death Rebel. This represents the trauma and darkness he holds in his heart. After each transformation is undone, Ikuto has no memory of his actions as Death Rebel. He first becomes Death Rebel in Chapter 31 of the manga and Episode 75 of the anime.
 * Appearance: In this form, Ikuto grows cat ears and wears a black suit and a black tie. He also sports an armband on his left arm, similar to the armband Amu wears with her school uniform.


 * Abilities: In this form, he is able to play the violin to take hearts' eggs and create material projections. His violin can turn into a Death Scythe, with which he attacks using Dark Night Storm. In the anime, he can also use an attack to take away a person's energy.

Seven Seas Treasure
In Chapter 38 of the manga and Episode 100 of the anime, Amu completely opens her heart to embrace Ikuto, causing the two of them transform together with infused power from Humpty Lock and Dumpty Key. While Amu becomes Amulet Fortune, Ikuto becomes the pirate Seven Seas Treasure with Guardian Character Yoru; a pirate which represents his freedom to do what he wants. This is only a temporary transformation.
 * Appearance: In this form, he wears a blue pirate outfit and an eyepatch, but keeps his cat ears. On the hat is a skull and crossbone symbol with a cat's head replacing the skull.


 * Abilities: Ikuto has a pirate sword for the attack Emerald Line: an attack to slash apart objects with sharp energy. He is also highly athletic.

Trivia

 * His character song is titled Tsukiyo no Marionette and comes from the album Shugo Chara! Character Song Collection 2.
 * Peach-Pit confirmed in a Q&A in volume 11 that Ikuto also knows how to play the viola and the piano.
 * In chapter 28 he told Amu he was in high school. In the Japanese school system, high school consists of only three years, as opposed to four in many Western countries. In comparison, in the Japanese school system, Elementary consists of six grades (as opposed to five in many Western countries) and Junior High school consists of only three grades, as well. Japanese high school consists of the ages of 15-16 (10th grade), 16-17 (11th grade) and 17+ (12th grade).


 * When telling Amu he was a high schooler (chapter 28), in response she replied "in spring I'll be a junior high schooler!". Japanese Junior high school ages consist of 12-13 in the 12th grade, which is the first year of Junior High school. The Japanese school year begins in April and ends in March, with Amu's birthday being September 24 falling in between there. That means in about five months after the school year starts, Amu will have already had her next birthday. In comparison, Ikuto's next birthday wouldn't be until December 1st.
 * As it was winter in chapter 28, as well, Ikuto's current age as of that chapter (17) / birthday of December 1st would have fallen right around there. That would mean at the start of the series (and when he first met Amu) he was likely actually a bit younger, and closer to a grade before/a year or so younger.
