Asahi Ōka

Asahi Ōka (, Ōka Asahi) is a middle-school student at Yotsuba University Affiliated Junior High School who's one of Mahiro Oyama's closest friends and classmates. She was originally friends with Momiji Hozuki and Miyo Murosaki, having known the former since elementary school. She later became friends with Mahiro through Momiji, and later befriended Nayuta Tenkawa through Mahiro. She is voiced by Kana Yūki in the anime.

Appearance
Asahi is a short, but extremely cute and athletic girl with short dirty blonde hair and green eyes. When she smiles, she has pointed teeth in the back of her mouth that give off the appearance of fangs. She tends to keep her hair hung in side pigtails, a style that Momiji gave her when they first met.

When not wearing her school uniform, she tends to dress in a very boyish style with shorts and tee-shirts.

Personality
Asahi is an extremely energetic and outgoing tomboy who speaks whatever is on her mind and is always looking to make friends with whoever she can.

Asahi comes off as a bit dumb due to her sheer energy and a tendency to say whatever is on her mind regardless of how it makes others feel. Despite this, she never means any harm by it and wants to be friends with everyone.

She has a habit of giving nicknames to anybody she meets, and sometimes these nicknames are picked up by her other friends. She calls Mahiro "Mahiron", Miyo "Miyochin", Momiji "Momijiro", and Nayuta "Nayutan".

Due to her excess energy, Asahi is a severe tomboy who loves to explore in her free time. She also has a habit of racing with Momiji who is also extremely athletic. In these races, Asahi tends to come out as the winner. Also due to being such a tomboy, with the sole exception of her school uniform, Asahi tends to only wear what can be considered boyish clothing much like Momiji. She has mentioned that she never feels cold, and doesn't wear tights even in the winter. The one time that she was shown wearing a dress, it miraculously tamed her wild nature, and she even admitted to feeling a little off balance in it. It didn't last though, as she quickly regained her adventurous spirit after eating some lunch. Despite this, both Mahiro and Kaede note how unbelievably adorable Asahi looks in dresses, and no one ever mistakes her for a boy the way that they do for Momiji.

Asahi has a naïve and innocent personality. Due to not having yet developed as a woman, she is completely unfamiliar with periods and never understands subtext involving them when her friends discuss them. It was shown that before she met Momiji, Asahi was also ignorant of the differences between boys and girls. She would always bathe with her older brother, and upon bathing with Momiji for the first time, she was confused and asked if "it" grew in later. Everyone around Asahi treasures her innocence and have done their best to help her maintain it for as long as possible. Momiji has refused to explain the concept of periods to her, and her brother Yuya claimed that a dirty magazine of his that she found was a magazine about wrestling.

Due to her energy and innocent personality, Asahi comes off almost like a pet. Mahiro noted that it was very soothing petting her head, and once noted that her spirit animal could be the dog due to her energy and playfulness.

Asahi's one weakness however is tests. When she has to face them, she loses all her energy and acts nothing like her usual self, even falling asleep during a few tests. Fortunately she has her friends to help her bounce back from these episodes.

Etymology

 * Although her first name Asahi (あさひ) is always spelled in hiragana and hardly ever shown in kanji, Nekotofu has revealed that the kanji is supposed to be 朝日, meaning "morning sun" (朝日) (asahi).
 * Her last name Ōka means "cherry blossoms" (桜花) (Ōka).

Trivia

 * In the original Japanese version, Asahi uses her own name ("Asahi") when referring to herself, which is considered cute yet somewhat childish and immature.
