Birthday: July 28 School: Hanasakigawa Girls' High School, 2nd Year, Class A Image Color: Orange Personality Active and Tomboyish: Bright, honest, and full of energy, though she has a slightly coarse side. She is the type whose body moves before her head thinks. Positive yet Stubborn: Basically a kind person who affirms others and treats them with respect. However, she also has a stubborn and strong-willed side, never backing down once she has made up her mind.

Basic Info Name: Miku Mahashi Band Part: Guitar & Vocals (Gt.&Vo.) Twin vocal setup with Raika Suga. Birthday: October 4 School: Hanasakigawa Girls' High School, 2nd Year, Class B Favorite Food: Fruit tart Character/Personality Proper Realist: She carries a polite, calm, and gentle atmosphere, but she is a strong-willed type who thinks about things realistically and firmly. Secretive Side: She does not interfere with others more than necessary and does not want others stepping into her own business. Because of this, she has a side that doesn't easily reveal her true feelings until she completely trusts someone and lets her guard down.

Basic Info Name: Yomogi Yakura Band Part: Bass (Ba.) Birthday: May 6 School: Shin-Sakura Women's University, Faculty of Information Design, Department of Digital Innovation, 1st Year (Currently on voluntary leave) Favorite Food: Wet rice crackers, Yokan, extremely spicy food (wants to like it) Personality Severe Stage Fright & Shut-in: A type who gets nervous very easily and is weak under pressure. She has a hard time interacting with people; although she entered university, she is currently on leave and shuts herself away in the band's dormitory. Hidden Longing for Delinquent Manga: She is actually a hardcore otaku for a certain "delinquent manga." In her heart, she longs to be strong and cool like the characters in those manga, and she constantly simulates "delinquent-like behavior" in her head (mental training). However, due to her actual personality, this is never reflected in her real actions. Usually timid, she is the type who finds humans scarier than ghosts. If she accidentally makes eye contact with a stranger, she panics: "Gyaaah! Please don't look into my eyes! I feel like my heart is going to be wrung out!?"

Basic Info Name: Chieri Umezato Band Part: Drums (Dr.) Birthday: April 2 School: Haneoka Girls' High School, 1st Year, Class A Favorite Food: Meat Visual Features: Pink long hair tied in buns (twin-tail style) with star-shaped hair accessories. Character/Personality Rebellious Girl: A girl in the middle of a full-blown rebellious phase—selfish, yet somehow hard to hate. Bright, Energetic, Clumsy but Persistent: She has a very strong desire for self-expression (wants to stand out), but because she isn't very sharp, she is bad at thinking on her feet and often fails. However, she never gets discouraged by failure. Incredibly Loud Voice: Her "loud voice" is such a major trait that it is specifically mentioned in her official profile. She uses proper polite language with older people or those she meets for the first time. When meeting someone for the first time, she doesn't call them by name, but starts with "Um..." or "Uh..."

Character/Personality Mysterious Youngest Member: In "Ikka Dumb Rock!", which consists of high school and university members, she is the only middle schooler (the youngest). Otherworldly Atmosphere: She is strangely composed for her age and speaks flatly in a somewhat difficult, sophisticated tone. Her unique values and way of thinking give off a mysterious air that feels somewhat detached from common sense. Genius Piano Skills: While she is indifferent to hobbies or things she likes, she possesses an abnormally high level of piano technique. She speaks in a calm manner, using phrases like "That was so" or "My apologies." Her use of casual speech is slightly robotic.
