Description
Rin Eba, the younger biological sister of Itsuki and stepsister to Yuzuki Eba, hails from Tokyo. Initially appearing as a petite girl with short red or pink hair just above her shoulders and often sporting a bored expression, her physicality transforms significantly over multiple years. She grows approximately half a foot taller and lets her hair lengthen. Her evolving style accentuates her developing figure—curves, hips, and breasts—resulting in a mature, noticeably different appearance that frequently causes others to fail recognizing her upon reunion. Her specific attributes include height increasing from 148 cm to 162 cm, weight 46 kg, blood type AB, and body measurements recorded as B86/W56/H87.
Mischievous and prone to causing trouble for others, Rin initially harbors a strong fondness bordering on a brother complex for Itsuki and expresses irritation toward Yuzuki, whom she accuses of seeking attention through niceness. She frequently tells lies aimed at upsetting Yuzuki. Despite this early hostility, their relationship improves considerably over time. Rin later exhibits a nearly promiscuous nature, using her evolving appearance and sexuality to provoke reactions. While her actions often serve her own amusement, they increasingly force other characters to confront their feelings, even as her methods remain manipulative and questionable. She experiences significant emotional turmoil, including depression, upon learning Haruto Kirishima and Yuzuki became sexually intimate.
Rin first appears seeking Yuzuki at the dormitory where Haruto's sister lives in Tokyo, revealing she incited Yuzuki's initial trip to Hiroshima. She refuses to accept Yuzuki as a sister, believing Yuzuki aims to take Itsuki away. Her words later haunt Haruto, prompting his return to Tokyo to uncover Yuzuki's true reluctance. Itsuki explains Rin's animosity stems from her infatuation with him. After Haruto confronts Itsuki over Yuzuki's pain, Rin overhears their conflict. A subsequent discussion among the Eba siblings resolves some issues, leading Rin to understand Yuzuki's friendly nature is misinterpreted as promiscuity. Rin forgives Yuzuki but, angered by Haruto hitting Itsuki, vows to target Haruto next—a threat fulfilled when she visits Hiroshima during summer break.
Living temporarily with Haruto and Yuzuki in Hiroshima, Rin becomes disruptive. Haruto assigns Takashi Yura to show her around as a distraction. Discovering Haruto's feelings for Nanami Kanzaki, Rin deliberately causes mischief, playing a key role in Nanami rejecting Haruto at a summer festival by informing her Haruto went to Tokyo with Yuzuki instead of shopping. After returning to Tokyo, Rin later encounters Haruto during his school trip seeking Yuzuki; she informs him Yuzuki isn't home, though Haruto glimpses Yuzuki inside. When Yuzuki ceases contact, Rin tips off Nanami that Yuzuki has a new boyfriend, prompting Haruto's move to Tokyo. She again meets him at her house, expresses disbelief at his pursuit, and claims Yuzuki isn't present despite Haruto spotting her.
Years later, Rin reappears working part-time at the same convenience store as an adult Haruto, her matured appearance surprising him. She announces her intention to attend Seijou University and convinces Haruto to give her a campus tour. After avoiding Takashi, who harbors lingering feelings, Rin finds Haruto discussing vacation plans with his girlfriend, Asuka Mishima. She embarrasses Haruto by clinging to his arm and proclaiming them a couple. Later, she confronts him outside work, challenging his love for Asuka and claiming she could provide a better time. Rin then orchestrates a situation forcing Haruto and Yuzuki to meet and spend a day together at Disneyland while she observes from afar.
Accompanying the Eba siblings on a visit to Hiroshima, Rin resumes troublemaking, involving Takashi and his new love interest, Kiyomi Asakura. She provokes Kiyomi's jealousy through overt flirting with Takashi—whether genuine feeling or mere chaos remains ambiguous. Following an argument between Asuka and Haruto over Yuzuki, Rin confronts Haruto about his conflicted emotions. Later, upon definitively learning Haruto and Yuzuki slept together after a year of dating, Rin realizes she harbors genuine romantic feelings for Haruto. She initially denies this, attributing it to being left out, but privately reassures herself their sexual relationship doesn't guarantee permanence, implying she retains interest.
In the series' first character poll, Rin placed 10th with 33 votes. Her popularity significantly increased in the second poll, achieving 4th place with 445 votes, potentially attributed to her physical and character development during the college era arcs.
