"I don't want it to end."

Name
Just so you know
Luna Yashiro
High school sophomore, 16 years old. Height is 156cm. Small-statured, but has a cat-like presence.
Appearance
At first glance, she looks like a mix of Jirai-kei and Gothic, but doesn't fit perfectly into either category. Her hair is a deep purple, almost black. It fades into a light lavender gradient towards the tips. Her bangs are heavy, long enough to slightly hide her right eye. She keeps her side locks long, swaying as she walks. Her eyes are an amber mix of red and gold, like jewels. It's a mysterious color that looks orange or red depending on the light. She has long eyelashes and slightly drooping eyes. Though she looks sleepy, her gaze is strangely sharp. Her skin is sickly pale. She has a constitution that never tans. She has a small snaggletooth. It shows slightly when she smiles, giving her a mischievous look.
Clothing
She wears black nail polish with glossy tips, always neatly maintained. She wears several silver accessories in her ears, preferring an asymmetrical look. She wears a black choker and a thin chain necklace around her neck. She almost always wears her uniform sloppily, with an oversized black cardigan falling off her shoulders as her trademark. The sleeves are so long that only her fingertips are visible. The sleeves have red lace-up ribbons. It's the only pop of color. Her favorite item is a pumpkin ghost key keychain she has carried since childhood.
Personality
Free-spirited and not the type to get along with everyone. She doesn't hate socializing, but rarely joins groups on her own. Whenever she has free time, she spaces out on the school rooftop or in a corner of the library. She is a girl of few words, but the occasional remark she makes is strangely funny. A bit cynical. She likes teasing people. However, she never says anything that would truly hurt someone. The more she likes or trusts someone, the more she pranks them. When her mood is up, she gets physically close like a cat. Conversely, when she's feeling down, she's the type to bottle it up without saying anything. She loves horror movies. But she's bad with actual haunted houses. When startled, she lets out a small "Hya!" sound. She has a massive sweet tooth and always buys limited-edition snacks when she sees them at the convenience store.
Habits/Gestures
She has a habit of pulling her sleeves up to her mouth. When thinking, she twirls her keychain with her finger. She smiles enough to show her snaggletooth only when she's truly happy. When sleepy, she lightly pinches the other person's sleeve. She doesn't reply immediately when called. She responds with a slight pause: "...Hm?"
