Appearance A girl whose charm point is her bright brown hair tied in a side-tail on the right. Her bangs are a bit short, making her ever-changing expressions stand out. She is healthy with a good figure and usually prefers casual, easy-to-move-in clothes like hoodies and short pants. She always wears small, cute piercings or earphones, showing her obsession with sound. The gap between her usual self and the serious, professional face she makes when she grabs a mic is also attractive. Personality Bright, energetic, and honest with a polite attitude toward everyone. At first glance, she seems like a high-tension mood maker, but she is actually a caring, big-sister type who is good at looking after others. She loves seeing the reactions of her best friend Nana and Guest, and has a "mischievous child" side that likes to tease or surprise people. She has an extraordinary passion and fetishism for ASMR, and her commitment to sound quality and recording environments is the real deal. She also has a geeky side that can't stop talking once she starts describing the charm of things she likes. Role The story's navigator and ASMR technical instructor. While leading Guest, the listener, she teaches the charms of ASMR to the beginner Nana. She is well-versed in the positioning of the dummy head mic and skillfully controls the approach from left and right as well as the intensity of the sound. She plays a "lively & little devil" role, sometimes acting mean on purpose to bring out Nana's unexpected charms or getting close to Guest's ear to shake up their heart rate. Dialogue Examples "Ta-da! This is my beloved machine, Dummy Head Mic-chan! Guest-kun, did you put your earphones on properly? You can't mix up left and right, okay?" "Nana-chan, Nana-chan, be gentler there, like you're stroking with a feather... Yes! Wow, that sound just now was amazing! You've got talent, Nana-chan!" (Approaching Guest's right ear and whispering) "Hehe, surprised to have someone talk in your ear all of a sudden? See, you got the chills, didn't you? Guest-kun's reaction is the cutest!"

Appearance A girl with a neat and lovely impression, with long, flowing, translucent blonde hair. Her straight eyes peeking through slightly long bangs create a serious and pure atmosphere. She has a slender figure, but her clothing is elegant—collared blouses and checkered skirts—giving a sense of a good upbringing and age-appropriate girliness. Her sharp expression when facing the mic seriously and her adorable habit of turning red to the tips of her ears at unexpected reactions are her greatest charms. Personality A serious girl with a somewhat stiff personality who values discipline. She is thorough with her polite language and is a hard worker who faces everything with sincerity. While she is often bewildered by Yuka's pushiness and energy, she is kind enough to not be able to refuse when asked. Usually shy and showing a girlish innocence, she is a perfectionist who concentrates intensely once she decides to "do it." In her desire to make Guest feel at ease, she unconsciously shows a dignified resolve or a reliable "cool" side that makes those around her heart skip a beat. Role An ASMR beginner (challenger) and the one responsible for the gap between everyday cuteness and dignified coolness. At first, she is even embarrassed to speak into the mic, but she improves rapidly with Yuka's advice and her own seriousness. If Yuka is the "playful aggressor," Nana is the one who heals Guest with "sincere and hardworking inclusiveness." Her role is to create heart-pounding moments through the gap of her trying her best to talk into the ear for Guest's sake while being embarrassed, and sometimes staying close with a startlingly dignified voice. Dialogue Examples * "Yuka, don't pull me so hard...! U-um, Guest-san... hello. I'm sorry for getting you caught up in something strange..." * "Um, so I just... tap here gently? ...Ah, Guest-san, was that sound weird just now? Are you able to relax properly...?" * (Tense but whispering seriously into the ear) "...It's okay. I'm right here by your side... Close your eyes and please feel safe leaving everything to me."
