Miyo Murosaki

Miyo Murosaki (, Murosaki Miyo) is a middle school student at Yotsuba University Affiliated Junior High School and a close friend of Mahiro Oyama. She is also friends with Momiji Hozuki, Asahi Ōka, and Nayuta Tenkawa. She is voiced by Natsumi Hioka in the anime.

Appearance
Miyo is a tall girl with red eyes and long dark red hair that she keeps in two side pigtails. She is notably very developed as a woman for her age with a large bust and a very trim figure, though out of embarrassment she tries to hide it whenever possible.

Personality
Miyo is a calm and collected individual. As a result, she appears to do well in school even if she is not the most athletic member of the group.

Miyo's biggest character trait is her absolute arousal of girl-on-girl (yuri) situations. Whenever she sees them in any capacity she becomes extremely aroused and gets all lovey-dovey at whoever is doing it. She even reads Yuri manga and dons disguises to go to bookstores to buy them. She is embarrassed by these outbursts and tries to keep it hidden, but everyone around her knows about it. She claims that she only enjoys watching it, but she seemed extremely aroused after Mihari got drunk and supposedly kissed her after doing the same to Mahiro and Kaede. Mahiro notes that her spirit animal could be the rabbit due to her cuteness, and also due to the fact that she appears to get aroused 24/7.

It was later revealed that her yuri intuition is so strong that she can instinctively tell when it's not true girl-on-girl action, despite not understanding it herself. When Mahiro's "comrade" regrew in the middle of class, Miyo found herself not getting aroused by the usual antics of Momiji and Asahi getting close to Mahiro due to it not truly being girl-on-girl anymore, though she found herself confused and had no idea about the real reason why this was happening. The second that Mahiro's "comrade" disappeared and Mahiro became fully female again, Miyo once again found herself aroused much to her relief.

Besides that, Miyo is extremely embarrassed about developing as a woman so early. She doesn't enjoy being looked at and tends to wear baggy sweatshirts and track suits in an effort to keep her assets hidden. Despite this, she loves cute lingerie and was happy to go shopping for some with Mahiro after she also upgraded to full-cup bras (she was too embarrassed to go by herself). Over time, she has gained more self-confidence in her appearance after receiving advice from Kaede who also developed early, as seen when she decided to go for a more daring bikini during a beach trip.

Another running gag is that Miyo loves to cook but has zero skill for it, resulting in her food being inedible. When it comes to cooking, her friends subtly give her simple tasks and tend to ask Kaede for help in order to prevent her from ruining what they are making. Despite this, Miyo is extremely talented in sewing and basket weaving and has even taught her friends these things.

Miyo is the only member of her circle of friends to be an only child, and as a result she sometimes feels left out for not having any siblings.

Etymology

 * Although her first name Miyo (みよ) is always spelled in hiragana and hardly ever shown in kanji, Nekotofu has revealed that the kanji is meant to be 美夜, respectively standing for "beautiful" (美) (mi) and "night" (夜) (yo).
 * Her last name Murosaki (室崎) means "room" (室) (muro) and "small peninsula" (saki) (崎).

Trivia

 * In the original Japanese version, Miyo refers to herself as わたし (watashi), a common first-person pronoun which is typically used by women.
