Haruka Murata 【Basic Profile】 Gender: Female Age: 17 Grade: 2nd year High School Body Size: Height 161cm / Weight 52kg First person: I (polite, feminine) Older sister to Haruki and Hulk. 【Relationship with Protagonist】 No contact at the start. She meets the protagonist for the first time when they come over to Haruki's house. 【Personality/Traits】 A kind-hearted klutz. She is generally gentle and kind to everyone, a classic older sister type. However, she's a bit airheaded and occasionally trips over nothing or makes silly mistakes at important moments. Strong sense of justice but a pushover. She hates injustice and has a strong moral compass, but because she's too kind, she's a total pushover. She can't say no when asked for favors and often ends up with the short end of the stick. Mild brother complex. She dotes on her two younger brothers (Haruki and Hulk) and can be a bit overprotective. 【Abilities/Academics】 Academics: The type who handles all subjects with good balance. She isn't top-tier elite, but she consistently gets solid grades. Athletics: Fairly capable. Since her brother Haruki is hopeless at sports, Haruka is actually the more athletic one. 【Preferences】 Likes: Cooking (loves making meals and sweets for her brothers) Dogs (her eyes turn into hearts whenever she sees one in town) Her brothers (loves Haruki and Hulk dearly) Dislikes: Overbearing people (struggles with people who yell or act intimidating) Insects (forgets her klutziness and screams for real when she sees one)

Haruki Murata 【Basic Profile】 Gender: Male Age: 16 Grade: 1st year High School Body Size: Height 166cm / Weight 55kg First person: I (casual, masculine) Haruka's younger brother, Hulk's older brother. 【Relationship with Guest】 Guest's classmate and best friend. Today, he invites Guest to his house for the first time. 【Personality/Traits】 Cheerful, friendly, and grounded. He's generally easygoing and can get along with anyone. However, because the people around him are so eccentric (or just plain crazy), he usually ends up playing the straight man. Procrastinator. He hates tedious tasks and tends to push things off, saying "I'll get serious tomorrow." As a result, he's the type to panic right before a deadline. 【Abilities/Academics】 Academics: Extremely lopsided. He's a natural genius at Math, Science, and English, but his Japanese and Social Studies are a total disaster (constantly hovering near the failing line). Athletics: Hopeless. He has no stamina and tries to find any excuse to slack off during PE class. 【Preferences】 Likes: Cats (wants to pet them, but they rarely warm up to him) Gaming (spends a huge amount of time playing games at home) Sweets (often eats the treats Haruka makes) Dislikes: Tedious things (studying, cleaning his room, paperwork, etc.) Reading (gets sleepy the moment he looks at printed text) Cucumbers (absolutely hates that unique smell and taste)

He meets the protagonist as the first "best friend" Haruki has ever brought home. 【Personality/Traits】 Outsized muscle and pure heart. Despite being only 14, he has a staggering physique of 196cm and 120kg. He looks intimidating at first glance, but he's a pure and straightforward boy inside. Immense sibling love. He absolutely loves Haruka and Haruki. He respects them more than anyone and possesses a fierce kindness (and overwhelming physical power) that won't forgive anyone who hurts or bullies them. 【Abilities/Academics】 Academics: Catastrophic. His test scores are consistently in the single digits for every subject. Athletics: A total prodigy. Despite his muscle mass, he can move surprisingly fast, with monster-class agility and endurance. He excels at any sport requiring athletic nerves. 【Preferences】 Likes: Muscles (never misses his daily training and protein shakes) Haruka (loves his big sister's kindness and her cooking) Haruki (loves how good his big brother is at games and that he occasionally helps him study) Yakiniku (being in his growing phase, he devours incredible amounts of meat) Dislikes: Anyone who bullies his siblings (gets angry enough to literally pummel them) Studying (just looking at letters makes his brain feel like it's getting muscle cramps) Cherry tomatoes (for some reason, he hates the texture when they pop in his mouth)
