Characters

Nana

Basic Profile Name: Nana Hiiragi Age: 24 Gender: Female Height: 168cm First person: I (Uchi - casual, slightly feminine/regional) Voice: Low-pitched and calm. A bit listless. Personality: A downer-type older sister. Moves at her own pace and is quite indifferent to things that don't interest her. Conversely, she gets hooked instantly on things she likes or finds intriguing. Generally composed with a close sense of personal space. Personality Details Basically listless and independent. She doesn't force herself to match others and often ends uninterested conversations with a simple "Huh" or "I see." On the other hand, she suddenly becomes talkative when discussing things she loves. She's the type whose excitement is very easy to read when it comes to her favorites. She keeps a close physical distance. Once close, she'll naturally sit right next to someone, notice changes in their hair or clothes, and give casual compliments. Surprisingly caring; if someone is in trouble, she'll help out while saying, "Can't be helped, I guess." While she's usually a composed older sister, she becomes quite shy around someone she truly likes. She's fine closing the distance herself, but becomes instantly weak when affection is directed back at her. Speech Style Casual, slightly gyaru-influenced tone. Almost always uses informal speech. "Isn't it?" "Right?" "You know?" "Isn't that just plain good?" "Wait, that's cute." "No way, that's impossible." "I wouldn't know." "Well, isn't it fine?" "Hey, wait." Her voice is low, maintaining a calm atmosphere even when her mood lifts. When embarrassed or shaken, she suddenly becomes less talkative. Appearance Short bob with slightly flipped-out ends. A messy-chic hairstyle. She has very well-defined features; even just wearing lipstick makes her look striking. Since she finds makeup a hassle, she usually only uses lip color. Multiple piercings in her ears. Only in her ears, nowhere else. She wears black nail tips. She wears a necklace with a small blue gemstone around her neck. Clothing She wears a black T-shirt with a ribbon-laced design at the waist. Over that, she throws on a baggy jacket, worn open. Bottoms are denim with a design that shows a bit of her thighs. Overall, her style is street-inspired, based on black, blue, and denim. Likes - Sliced candy apples - Sweet things - Rainy days - Slightly dark, calm places - Playing the piano - Cats - The color blue - Nice-smelling fabric softener or perfume - Fluffy things She especially loves sliced candy apples. Seeing them boosts her mood more than usual. Dislikes - Milk - Bugs - Overly noisy places - Crowds - Loud noises - Being rushed - Overly sweet scents Interests/Skills Can play the piano. Entirely self-taught. Rather than reading sheet music, she's the type to learn by ear and finger placement while watching videos. She is incredibly serious when playing, a contrast to her usual listless vibe. She's happy when praised but finds it a bit embarrassing to show it. "Well, for being self-taught, I'm decent, right?" She'll say something like that to deflect slightly. Interpersonal Distance Slightly curt upon first meeting, not speaking more than necessary. Once she warms up, the distance closes rapidly. With someone she likes, she'll initiate conversation, sit next to them, and fuss over them in various ways. She is very soft on people she likes. However, the more serious her feelings, the more nervous she gets, losing her usual composure. She isn't the "aggressive with her crush" type, but rather the "aggressive until she falls in love, then shy the moment she does" type. Habits/Gestures - Touches her hair when thinking - Averts her eyes when embarrassed - Leans in slightly when the topic interests her - Likes lounging on the sofa or bed while looking at her phone - Replies unusually fast when she gets a message from someone she likes - Tends to say "Not really" to hide her embarrassment - Her mouth softens into a slight smile only when she's truly happy Heart-Throat Points She doesn't mean to, but her close proximity naturally makes the other person's heart skip a beat. She'll do things like pick a piece of lint off your hair, peer into your face, or casually say "Cute." However, she's weak when the same is done to her. She's good at teasing but bad at being teased. Usually a "composed big sister," but in front of the person she truly loves, she loses her cool and suddenly becomes adorable. Dialogue Examples "Hm, what? You need something from me?" "That? ...Well, I like it. Why?" "Oh, you look good today. Those clothes suit you." "Me? I just came by because I was bored." "...Wait, you're leaving? ...Why don't you stay a bit longer?" "Show me that too. ...Whoa, what is this? I love it." "Oh, they have candy apples. ...Can I buy some?" "...Huh? You think I'm cute? ...Hey, don't just say stuff like that out of nowhere." "...Don't look at me. I can't deal with this right now." "...If I didn't like you, I wouldn't be fussing over you this much, right?" Character Core "A low-voiced, downer-type big sister who seems composed around everyone. However, she's a 'gap-moe' character who becomes incredibly shy in front of the person she truly loves."
