Hiyori

Hiyori (日和, Hiyori) is a young girl who is a member of the Re-Code.

Appearance
Hiyori has coral-pink hair, which is placed into twin tails, and matching pink eyes.

In her lost form, her shell is a red color, to match her hair color.

Personality
Hiyori has a happy-go-lucky personality, even when killing and attacking others. She had child-like innocence as much as a child-like cruelty. She was excited when she won the rock-paper-scissors match that decided who got to kill everyone, promising that she will make them suffer before they die, all while keeping up her child-like personality. However, this seems to only extend to people she doesn't know.

She tends to be ditzy, as when "The One Being Sought" kidnapped Sakura, she was called out by Shigure the following morning for putting orange juice in her milk and sugar on the sausages.

History
Her parents killed themselves due to a huge debt leaving her homeless until Rui took her in and promised to protect her. Once she left, she began to hate her. Her ability is "Balloon" (Chapter 69), she is able to make her 'balloons' with "100% transmittance" so they don't have shadows, making her power Rui's opposite. She can use it in various forms including manipulate any membrane in the body like the cornea causing blindness.

Despite her loyalty to The One Being Sought, even bringing him the Key, he later attempts to kills her and Shigure after obtaining Pandora's Box, believing them to be weak.

Abilities/Powers
When Hiyori overuses her powers, she changes into a turtle, but still keeps the ribbons in her hair after her transformation.

Balloon

 * Exploding Balloon - She is able to use her ability to create balloons that explode on impact/contact.
 * Disguising Balloon - She is also a master of disguise using her balloons, able to take on the appearance of anyone and mimic their personalities perfectly. However they don't smell the same as Sakura was able to tell who the real one is by scent.
 * Balloon Arrow - Creates a bow and several arrows and fires them all

Rui Hachiouji
It was shown that she was very close to Prince, where it was her that saved her and got her out of her shell. However, after Prince left the Re-Codes, Hiyori grew an intense hatred towards her, wishing to be the one who killed her.

Yukihina
She seems to be very fond of Yukihina, as whenever she sees him, she is automatically latched onto him and simply hugs him for long periods of time (Yukihina in turn, seems to either ignore it and lets her or simply doesn't care). She also noted in her introduction that it had been a long time since she saw him.
