Amaterasu is a character from the Sister's Story series, portrayed by Hatsune Miku.

She is the younger sister of Tsukuyomi. Both she and her sister are named after gods in the Shinto religion.

She killed her sister on their 7th birthday after a petty argument between them both.

## Appearance

Amaterasu's design has three versions throughout the series.

In the PV of "Watashi no Nanatsu no Oiwai ni," Amaterasu is shown as a young child with long, dark, turquoise hair in pigtails and a golden hairpin.

She wears a pink kimono with grey obi and sashes, ending with white stockings, matching with her sister.

Later on, as a 19-year-old, she wears the same clothes but now has two grey ribbons instead of a hairpin.

After she starts losing herself and forgetting who she is, Amaterasu takes half of the hairstyle of the deceased Tsukuyomi.

In her canon design, her hair color is gray instead of turquoise, and she styles her hair in a single ponytail instead of pigtails.

## Personality

Not much can be known about her personality, but assumptions can be made.

Amaterasu was young and was mentioned to be playful and immature compared to her sister, who was the opposite of her.

## Relationships

### Tsukuyomi

Amaterasu is Tsukuyomi's younger sister. Not much is known about how they felt about each other, but assumptions can be made.

On one side, it can be seen that Amaterasu loved her sister dearly, caring for her and helping her; an example of this is Amaterasu aiding Tsukuyomi with her eyesight and Tsukuyomi aiding Amaterasu with her troubled way of speaking.

On their seventh birthday, after killing her sister, Amaterasu sings and dances around her grave about how much she loved her.

On the other hand, it can be seen that Amaterasu was envious of Tsukuyomi's beauty and her gain of praise from their peers, which, after a petty fight, led her to stab her sister in the abdomen with a staff, killing her instantly.

## Theories

* Whether Amaterasu loved or hated her sister is difficult, as many facts in the story contradict each other. One theory states that she truly loved her sister, had a great relationship with her, and killed her because she "loved" her.

* On the other hand, this love can be interpreted as Amaterasu doing her sister a "favor," as in she killed her because she could take her place and become a much better her.

* The reason for Amaterasu's envy of Tsukuyomi is her beauty and gain of praise, but there is a theory that she was jealous mainly because of the fact that the sisters are twins and look almost identical, so there is practically no reason for one twin to look "beautiful" than the other.
