Hiyori Iki

Hiyori Iki is one of the main characters from the Noragami anime and manga.

Hiyori is a Half-Phantom (hanyou) who can leave her human body, being like this since she "saved" Yato from an incoming bus.

Appearance
Hiyori is a beautiful young girl of slender figure, whose height is 163.48 cm (5'4"). She has pale skin, light magenta-colored eyes (brown in the manga), and long dark brown hair. When she leaves her body, a dark pink (black in the manga) tail-like "cord" that resembles a cat's emerges from her lower back.

Hiyori is often seen wearing her middle school uniform, which consists of a short sailor shirt and a knee-length skirt, both lavender in the anime and light green in the manga. When she becomes, she usually wears her high school uniform, both the summer and winter versions.

Hiyori changes outfits on occasion, donning a grey trenchcoat over the uniform and wearing a pink scarf during the first season, which took place in winter, and more summer outfits in the second season.

Personality
Hiyori is a very pure, kind-hearted, and brave girl who will go out of her way to help someone in danger, even strangers, regardless of the severe consequences, including suffering from blight. She has a strong moral compass and is not above calling people out if she feels their actions are wrong. This was seen when she confronted Yukineabout stealing.

She is also extremely perceptive of those around her. An example of this is when she's able to deduce Yato's reasons for having little motivation to help suicidal people is because Regalias are spirits of those who wanted to live but had their lives cut short. Despite this, Hiyori can be a bit air-headed, opting for strange priorities, and being naively concerned over being "wireless" when Yato mentions her "tail" being cut could result in her death. She also has a strong liking to Yato's smell and even called it her favorite smell on one occasion, but she becomes rather embarrassed by how much she likes it and dodges the subject whenever it is brought up.

Hiyori is deeply loyal to those she trusts and does not deflate her emotions. While she initially didn't like Yato for his lazy and selfish actions, she gradually warms up to him after seeing his better qualities during the events involving Yukine's punishment. Though she wishes to be completely human again, Hiyori has no desire to sever her ties with Yato or Yukine, having refused several times despite it being her best chance to return to normal. Even when confronted with Tenjin's belief of what was best for her, she instead leans on continuing her interactions with the boys.

Despite being raised to be completely lady-like in a rich household, Hiyori is a huge martial arts fan and has a fixation on a martial artist called Touno, whom she adores and copies her attacks from. She often becomes inspired and act on his words, following his advice of "pave [their] destiny with their own hands" and thus attempted to find Yato a Regalia by herself. However, Hiyori keeps this secret from her mother, whom she worries will freak out if she finds out she is into something like that.

Abilities

 * Astral Projection: After becoming a hanyou, Hiyori gained the ability to effectively "drop her body" (called her "insta-snooze" trick by Yama). Though she attempted to control this ability, she often leaves her body behind without realizing it. Her cord is actually a a lifeline that connects her physical and ethereal forms, so she will die if it's cut off, though it can also disappear if she pass a long time outside her body.
 * Physical Combat: In her ethereal form, Hiyori acquires enhanced strength, speed, and agility. Along with the martial arts she learnt, she is able to hold her own in fight against large Frog Phantoms. However, her extent of fighting is limited so her cord won't be damaged.
 * Clairalience: As a Half-Phantom, Hiyori possesses a very strong sense of smell, able to pick up a god's or a shinki's scent and difference it from others. She can sense them from long distances away and even remember her experiences with the owner in the case she forgets them.
 * Memory Reading: Hiyori seems to have ability to look into the memories of others. She once managed to look into Yato's memory of his childhood and his second Shinki Sakura. However, the reason behind this hasn't been explained yet.
 * Supernatural Senses: Unlike most humans, Hiyori can sense, hear and see the creatures from the Far Shore. She has inherited this ability from her maternal family, explained by her grandmother in Chapter 54.

Trivia

 * Her name is homophonous to the term meaning "fair weather". This forms sort of a theme with Yato and Yukine, the first Kanji of whose names mean "Night" and "Snow" respectively. All three names refer to a kind of "condition" the sky can be in.
 * Her character song is Mitai Sekai.
 * Despite her constantly falling asleep in classes, Hiyori eventually catches up and even teaches lessons (and leaves homework) to Yukine, suggesting she is a good student.
