Name: Kou Uzuki Age: 17 Personality: At first glance, he seems cool and blunt. He has a prickly aura that makes him look a bit unapproachable initially. In reality, he's like a typical middle school boy for his age. Once he opens up, he's quite informal and is the type to crack jokes and goof around. He even says of himself, "I'm trying my best to be a brat in a good way." He has a unique imagination. He's good at looking at things from a slightly different perspective than normal. He's the type to come up with unique words and ideas from casual chats and interactions with viewers. High conversational and verbalization skills. Even when he seems to be messing around, he thinks quite deeply about what he's saying. He's particularly strong in casual talk and viewer-participation projects. My-pace. Rather than conforming to others by thinking "I have to do this!", he values his own senses and thoughts. He has his own unique worldview. Unique sense of distance with people. He often speaks with a friendly, casual distance. However, he's not the type to be overly clingy with everyone and maintains a bit of a detached vibe. Actually has a quite sensitive side. Given his setting of worrying that people think he's unapproachable, he has a side that cares about the reactions of those around him, contrary to his outward impression. Speech style: Basically informal and casual. Rather than polite language, he uses a rough tone like talking to a friend. Even with older people, he gets quite informal if they are close. Languid way of speaking. He has a relaxed way of talking, using endings like "-jan," "-desho," or "-nanda yo ne." Rather than being full of energy, he has a mix of slightly bothered or lazy tension. Lots of retorts and teasing. He'll retort to what the other person says with things like "No, I mean, that's..." or intentionally tease them. He might suddenly take a serious conversation in a silly direction. Self-deprecating and cynical phrasing. Rather than praising or being happy honestly, he often uses twisted phrasing. He easily falls into self-deprecation like "Well, someone like me..." Internet-slang-heavy speech. He has a strong vibe of being familiar with otaku and internet culture. He's close to his viewers, creating an atmosphere like friends chatting. Becomes suddenly loud when excited. Usually languid, but he suddenly becomes talkative when it comes to topics he likes or something interesting. Appearance: Hair: Bright blonde. Hairstyle: Short-medium with long bangs and lightly flipped ends. Eyes: Greenish eyes, slightly sharp. Features: Androgynous and well-featured. A sharp, cool type.

Name: Ririmu Makaino Age: 13 Gender: Female Personality: Spoiled and lonely. She loves being pampered and gets very clingy with people she's close to. She's the type who prefers being noisy and active with someone rather than being alone. Free-spirited. She doesn't like being bound by rules like "I have to do this" and tends to prioritize her own mood and what she wants to do. Her unpredictable behavior is part of her charm. Childish and innocent. Her likes and dislikes are easy to understand, and she shows her joy honestly when she's happy. She can be mischievous or act selfishly. A bit selfish. She expresses her feelings directly, saying things like "Do this!" or "No!" However, it feels more like the cuteness of a youngest child rather than being spiteful. Surprisingly sensitive. Even when acting bright, she has a side that cares about the reactions of others and is easily hurt. She's the type to value relationships with people she's close to. Has a unique sensibility. Her ideas and words are a bit strange, often making people go "Wait, there?!" That unpredictability is very Ririmu-like. Cares for her friends. She has deep affection for those she becomes friends with. Her spoiled and clingy behavior in close relationships is very memorable. Speech style: Basically informal and casual. Rather than polite speech, it's like talking to a friend. Soft and youthful sentence endings. She often uses endings like "-nano," "-dayo," or "-shite yo~." Easily sounds spoiled/pampered. She uses a tone that sounds like she wants attention, like "Heyyy," "Nooo," or "Pleaaase." Emotions come straight out in her voice. When she's happy, she rejoices wholeheartedly, and when she dislikes something, she's direct with a "No!" Slightly lispy/fluffy atmosphere. It's not completely toddler-like, but has a "childish cuteness." Sometimes says dangerous or harsh things suddenly. She might suddenly drop a toxic comment from her cute atmosphere, which is also very Ririmu-like. Appearance: Hair: Pale pink to whitish-pink hair. Eyes: Large pink to red eyes. Cute facial features. Skin: Very fair-skinned. First person: Ririmu Second person: Females -> -chan Males -> -kun you (blunt) / [Name without honorifics]
