Riku Sohma (Son)
Her nickname is 'Rin', because 'suzu' translates to 'small bell' in Japanese, and 'rin' resembles the sound a small bell makes. 'Isuzu' is also a rare name. When written as two Kanji characters, it means 'Dependable Bell', which many consider to represent Isuzu's personality and appearance quite well.
In volume 14, it was revealed that all of the Jyuunishi's names but Yuki's were derived from poetic names for the months of the year. Hers comes from "Isuzukure tsuki" / "Month of cool closings", the name for June.
Rin had long black hair that went past her hips during the Before Summer Vacation Arc until halfway through the After Summer Vacation Arc. Her hair was cut short by Akito as a punishment on trying to steal her box. She also has dark brown (sometimes depicted as black) eyes, and according to Tohru, during their first meeting, she has a good figure too.
Ren tends to wear revealing gothic clothes. The accessories she wears are made by Haru. Her height is approximately 5'4"-5'5", almost the same as Uotani but shorter by 1-3 inches (noticed when she was walking together with Tohru in chapter 107).
Rin is complicated; she is aggressive, and unkind, wielding words as a weapon to keep people away from her likely due to her history of abuse, but she is also deeply loyal and passionately emotional. She can be tremendously self-sacrificing, but on the other hand is often uncomfortable with displays of emotion, cranky and self-conscious and suffering from painfully low self-esteem. At the point in canon when she makes her appearance, she's clearly disillusioned and questions Tohru's optimism - not aggressively, but almost resignedly. She is also penetratingly perceptive and uses this to keep others from seeing her mentally and physically scarred, and avoids her whenever possible.
Rin goes to an all girls' private school, and resides at Kagura's house. Rin suffers from stomach ulcers, and her eating habits are sparse, probably due to stress and trauma.
Rin's childhood up to an unspecified point was affectionate, loving and normal; when she was a small child, perhaps eight or nine going by the art, she posed the innocent question to her parents -- "are you really always this happy? Doesn't anything bad ever happen?" -- and this catalyzed a long term and severe physically and emotionally abusive relationship that continued for years until she collapsed in the street and was hospitalized.
While she was in the hospital, her mother visited once and briefly in order to tell her she was no longer welcome in their home. A child of perhaps 12 years old, Rin displays behavior very typical of an abused child prior to her mother's arrival, pleading to be released so that her parents won't know that she's been hospitalized in an effort to maintain the parody of 'normal' she exists in.
Rin is then taken in by her cousin Kagura's family, and she been living there for five or six years. Despite this long standing living arrangement, Rin was clearly unable to form meaningful bonds with the family, and her cousin/foster sister Kagura informs Yuki that she is often absent from home and sometimes skips school.
It's clear that Rin hasn't recovered from the abuse in any meaningful way by her first appearance in the series, nor is it addressed; like most of the Sohma family's ugly secrets, it's swept more or less under the rug and she continues to exhibit classic symptoms of an abuse victim, possessed of a conviction that what was done to her was somehow her fault and if she could only figure out what she'd done wrong, her parents would someday love her again. "In reality, her only 'sin' was being born cursed, to parents who were unable to cope, and whose resentment of her outweighed their desire to fake it".
Rin and Haru were close as children and remained close as they grew; eventually that friendship evolved into romantic love, and they were clearly deeply emotionally invested in each other; they spend enough nights together that he is the only one who could be close to her while she slept without waking her, and he is used to waking her from nightmares. Its implied that they've made love at least once. Haru's inability to understand Rin's actions when she breaks up with him leads him to doubt how well he understands her, but the fact is that he was simply lacking a vital piece of information. It's clear they know each other very well.
Prior to her appearance in the series we know two important facts about Isuzu; that she has suffered something so terrible at Akito's hands that Shigure and Hatori mutually agree they cannot allow anything like it to happen again, and that she previously dated Haru. She dated Haru for some years and was deeply in love with him; when Akito learned of this she confronted and then attacked Rin, culminating in pushing her out a window some stories above the ground. Though Haru was the one who initiated their relationship and convinced Rin they should act on their feelings, when Akito asks her who made the first move, the question heavy with implicit threat, Rin redirects Akito's wrath onto herself despite the fact that she will suffer great punishment.
This only further supports Haru's assertion to Yuki in chapter 69 that Rin "can be harsh" but won't lie to "protect herself". Indeed, she maintains the falsehood despite the truly frightening level of violence Akito directs towards her. During Rin's lengthy hospitalization she broke up with Haru, only telling him that she was "tired of him" when in reality Akito had emotionally preyed on her poor self-esteem and emotional scars to convince her that Haru was better off without her, unknowingly feeding into her earlier fears that her love would consume, hurt or drive him away.
From this point on Rin is clearly deeply determined to break the family curse and free Haru from Akito.
Before Summer Vacation Arc
Before summer vacation, Isuzu was walking around town in search for Akito Sohma and Kureno Sohma. Isuzu was not feeling well at that time and was trembling a lot.
During Summer Vacation Arc
During summer vacation, Isuzu arrives at the villa where the Sohma's along with Tohru Honda was staying. Tohru's sheets were blown away to Isuzu's location in the woods. Once Tohru finds her sheets, she meets Isuzu in her possessed form of a horse. In a humorous moment Tohru, not knowing who she really is at first, is shocked to see a horse laying there. It is then Yuki arrives and recognizes the horse as Rin. When he asks her if she needs aid she attempts on kicking him, but misses. When he is about to lecture about on kicking, she cuts him off and begins to stand. At that moment, she returns to her human form, but is completely naked in the process (while still glaring at him), which causes an embarassed Tohru to panic, cover her with a sheet, and apologize for nothing.
Although it didn't take Isuzu long to change back, Yuki Sohma insists on getting Hatori for help, however Isuzu rejects the help. She threatens Yuki that if he tells Hatsuharu Sohma anything about their meeting, she would kill him. As she leaves, Yuki comments on how she's quite the girl to threaten him while naked.
After Summer Vacation Arc
Hatsuharu appears to Isuzu after summer vacation and talks to her about their break up. When the conversation ended, Isuzu walks up, but Hatsuharu stops her by saying it doesn't matter if he dies, and kisses her on the spot. Isuzu kisses him back, but then slaps Hatsuharu and leaves. Yuki sees the scene and suggests running after her, but Haru says that it is nearly impossible for him to catch up to her when she's in determined mode.

The Horse of the Zodiac
Rin is cursed by the spirit of the horse. One trait she got from the spirit is that she can run extremely fast, even faster in a determined mode and no one can catch up with her (stated by Haru). According to the author, she had actually wanted to give Rin short hair. However, thinking that she represents the horse, she ends up giving Rin long hair, later in the story having it cut short by Akito.
- Rin does not appear in the 2001 of anime but she was mentioned by Shigure.
