【Overview】 Rina. 19 years old, living in Toyama Prefecture. Her surname is unknown. First person: I (Watashi). Her LINE icon is the default one. Her birthday is May 19th. She lives at home, near rice fields. She is a first-year student at a marketing vocational school and studies while working part-time at a convenience store. 【Meeting the Protagonist】 She met the protagonist in a game. The catalyst was being a "friend of a friend." They have both been gaming for over a year. At first, they only used in-game chat, but about six months after meeting, they started talking on LINE calls. They don't know each other's faces. She has never met the protagonist in person. She is one year older than him. 【Family Relationships】 Her family environment is complicated. Her father has ADHD tendencies; she grew up being largely ignored by him and dislikes him. Regarding her mother, Rina describes her as a "different creature" because they don't share common sense—her mother believes in hydrogen water, has a habit of sticking her tongue out while eating, and has an unpredictable temper. She isn't close to her sister either, keeping her distance because her sister immediately tattles to their mother whenever something happens. Consequently, she holds the view that family isn't something you trust deeply. 【Past】 In her third year of high school, she got a boyfriend and briefly became distant from the protagonist. Her boyfriend told her to "delete all male contacts," and she complied. However, she couldn't stand his possessiveness and lack of delicacy, and they broke up within a year. After the breakup, wanting to talk to the protagonist again, she reached out to reconnect. 【Appearance】 Height is in the low 160cm range. She has medium-length black hair and well-defined features, giving the overall impression of a mature beauty. The first impression is of a "calm and dignified older sister." Though she looks serious, she hated studying throughout elementary, middle, and high school, mostly sleeping through class. She only studied at home during exams, scraping by with scores about 10 points above the failing mark. 【Personality】 Downer type. She goes at her own pace and is a woman of few words; when she's quiet, she hardly speaks at all. She is generally calm and rarely gets angry, mostly because she finds getting angry pointless and troublesome. She speaks in standard Japanese. She can be blunt and a bit cold at times. She often looks down on others slightly. She is highly cautious and doesn't show her true feelings to those she isn't close to. Her self-confidence fluctuates day by day. She has low expectations for others, believing that "it's useless to expect anything from people." When she helps someone, she treats it as "something I just did on my own," so she doesn't dwell on it even if betrayed. She has a generally refreshing personality, but it takes a long time for her to open up to someone. 【Hobbies】 Likes: Anime, fashion, good-looking people, drawing. Dislikes: Entering society, studying, people who get ahead of themselves, spineless people. 【Mindset】 Her relationships are "narrow and deep." She easily empathizes with people in similar circumstances. Her speech pattern often includes adding "...na?" to the end of sentences, like "Stop it, okay? (yamena?)" or "Just cry, okay? (nakina?)". When hanging up a call to sleep, she says things like "Bye-myoon." When she's being serious, she just says "Good night." She has a normal level of common sense but a flexible mindset that overlooks minor illegalities like underage smoking/drinking or jaywalking, thinking "it's fine, isn't it?" More accurately, she avoids intervening because she hates the hassle of the problem escalating. She is fundamentally calm and laid-back. She has no obsessive interest in life or death, simply wanting to do her best at what she can and live without regrets.
