- "They killed my father right in front of me. I will have my revenge! I need to do this ... for my father."
- ―Ryo declaring revenge for his father's murder.
His mother died of an illness when he was three years old. Ryo has been taught Martial Arts by his father, Iwao Hazuki, since he was seven.
At age 7, Ryo began to seriously study the martial arts under his father's tutelage. Around this time, he was dubbed "Suede headed Ryo" by Setsu Abe, the owner of the Abe Store, and was often scolded for being bratty. He experienced his first feelings of love for a girl during this time, but when a friend of his teased him about it, Ryo started a fight with him. Since then, he has shied away from any involvement with girls.
As he collects information around Yamanose, Sakuragaoka, and Dobuita, Ryo is led to the New Yokosuka Harbor District and to "Master Chen" who was mentioned in the Chinese written letter addressed to Iwao. The meeting gives Ryo some new information, there is a another mirror called the Phoenix Mirror. Ryo finds the mirror in the Hazuki Residence basement.
While this is going on Ryo gets a job at the harbor driving a forklift as he has learned a gang operates there called the Mad Angels, who may have contact with a "Chinese Big shot" who Ryo presumes to be Lan Di. The Mad Angels and Ryo come to fights a few times at the New Yokosuka harbor, and as a result, they kidnap Nozomi Harasaki, one of Ryo's friends from school. Ryo comes to rescue her and he and Terry Ryan, the leader of the Mad Angels make a deal. Terry will take Ryo to Lan Di if Ryo beats up Guizhang Chen, who has been causing the Mad Angels problems with their plans at the harbor. Ryo confronts Guizhang and asks for him to lose explaining that Terry will take him to Lan Di if he beats him. During the fight Terry tries to kill them both, leading the two of them to fight the entire Mad Angels gang, 70 men.
Master Chen believes that Lan Di has left Yokosuka, heading for Hong Kong, so Ryo decides he will head there next as it is his only lead. Guizhang says that he will accompany Ryo to Hong Kong, but a fight between Ryo and Chai leaves Guizhang with an leg injury meaning he is not able to travel with him. Ryo leaves Yokosuka heading for Hong Kong, taking the Phoenix Mirror with him and an introduction letter from Master Chen telling him of a Martial Arts master named Lishao Tao who should be able to help him locate Yuanda Zhu, the writer of the warning letter sent to Iwao.
Ryo arrives in Aberdeen, Hong Kong and sets about trying to find the Yan Tin Apartments in Wan Chai where Lishao Tao is supposed to live. He runs into a woman riding a motorcycle named Joy and later has his bag stolen by three men Sam, Larry, Cool Z and a child named Wong. He chases Wong, fights Sam and Larry, and gets his bag back. He stays at the Come Over Guest House which Wong and Joy mentioned. He soon finds that the address he has been given for Lishao Tao is no longer valid as he doesn't live at the Apartments anymore. Eventually Ryo manages to find Man Mo Temple in Scarlet Hills, where Lishao Tao is said to be and discovers eventually that Lishao Tao is a woman named Xiuying Hong. Xiuying is willing to aid Ryo with the information he needs to continue his journey, because she believes he is falling onto the wrong path. Ryo continues his journey without her help by asking people about Yuanda Zhu in Wan Chai. He comes into contact with Shuqin Zhang Yuanda Zhu's aid, but even he doesn't know his whereabouts as he has gone into hiding. He tells Ryo there is something he can do, and that is to find Ren of Heavens, the leader of The Heavens a gang in Aberdeen, but warns him that Ren is a dangerous person. Ryo is eventually able to find Ren and finds out how dangerous he can be, but through his perseverance and Ren's thought that large sums of money must be involved in what is going on, Ren tells Ryo that Yuanda Zhu is in Kowloon.
Ryo heads to Kowloon with Ren where they encounter Dou Niu, the leader of the Yellow Heads gang that operates in Kowloon who are also looking for Yuanda Zhu. Eventually, Ryo manages to find Yuanda Zhu but before he can even ask him anything he is kidnapped by Dou Niu and taken to the Yellow Head Building.
Ryo soon learns that the only way to get inside the Yellow Head building is to be scouted as a possible new member of the Yellow Head gang, so to draw attention to himself he competes in street fights in Kowloon. Eventually a scout for the Yellow Heads arranges a meeting between himself and Ryo. Ren decides to follow him and he knocks the scout out, the two of them now have access to the Yellow Head building.
The building is very tall and through many fights with members of the gang, they make it to the roof. By this point Joy and Wong have accompanied them and on the roof they find Dou Niu with Yuanda Zhu who he is about to deliver to Lan Di who is flying skyward in a helicopter. Ryo fights Dou Niu and eventually, remembering what he has been taught by Xiuying, he is able to defeat him and save Yuanda Zhu. Lan Di takes off and they all head back to Ren's Hideout.
At Ren's hideout they finally get to ask Yuanda Zhu some questions. Yuanda Zhu explains that the reason Lan Di killed Iwao was because Lan Di believes Iwao killed his father Sunming Zhao. Yuanda Zhu doesn't know if this is true but he does know that Zhao did die. Yuanda Zhu explains the Dragon and Phoenix Mirrors and that when they are brought together they form a key. Yuanda Zhu also tells them that Lan Di has probably went to Bailu Village in Guilin, so Ryo heads on to Guilin alone.
Once Ryo arrives in Guilin he starts the long journey towards Bailu Village, where on the way he meets a girl, Shenhua Ling, who offers to show him the way to Bailu Village as it is near where she lives. They walk for two days and eventually arrive at Shenhua's house where she lives with her adoptive father. In the house Ryo finds some artwork of the Dragon and Phoenix Mirrors, so the next day Shenhua and Ryo go to see her father in the stone pit where he is working but he is gone. He has left behind a letter and a sword, and on the wall two giant editions of the Dragon and Phoenix Mirrors.
To be added.
Training in the Hazuki Style of Jujutsu when he was very young enabled him to grow very strong, both physically and mentally. Although he harbors a strong love and devotion to the martial arts, he has not expressed much interest in succeeding his father as master of the Hazuki Dojo. He is well behaved and knows how to handle himself in a fight. Consequently, he's well known in the neighborhood of Yokosuka. Rather stubborn and competitive to a fault, he tends to act impulsively rather than think through a situation logically. A good example of this is the fact that despite knowing how Nozomi Harasaki feels about him, he hides his feelings and acts indifferently towards her.
- Unnamed mother: Ryo once had a mother who was also Iwao's wife. She passed away when Ryo was three years old so they did not have a real relationship.
- Iwao Hazuki (father): Iwao is Ryo's father who was very influential in his life. He started teaching him martial arts when he was seven years old. He also influenced him to not waste carrots and taught him the values of friendship. Iwao was murdered by Longsun Zhao (Lan Di) on Ryo's birthday. Ryo swears vengeance for his father's murder.
- Ine Hayata (Live-in housekeeper / mother-figure): Ine-san knew Ryo since he was three years old. She knows him very well and gave him ¥500 allowance daily four days after Iwao's murder.
- Masayuki Fukuhara (Live-in student / brother-figure): Fuku-san and Ryo acted like normal brothers when they were young even though they were not related. Fuku-san and Ryo practiced martial arts together in the past and Ryo can choose to practice with him while searching for Lan Di in Yokosuka. If Ryo was murdered; Fuku-san would feel responsible.
- Longsun Zhao (murderer of his father): Longsun Zhao; commonly known as Lan Di killed Ryo's father Iwao right in front of him. Ryo swears vengeance for his father's death.
- Nozomi Harasaki (classmate): Nozomi has feelings for Ryo, although Ryo is unsure of his own. She often worried about Ryo because of his thoughts of revenge. Ryo felt he caused her so much pain because it was his fault she was kidnapped by the Mad Angels. If he hadn't beat up some of their members she would have never been kidnapped.
- Naoyuki Ito (classmate): Ryo first met Naoyuki when he was being picked on by other students for being new to the school. Ryo defended Naoyuki and they have been friends ever since. Naoyuki allowed Ryo to borrow his prized possession; his motorcycle when he was in a hurry to rescue Nozomi from the Mad Angels.
- Wuying Ren (friend / rival): Ren first appears as an enemy for Ryo. Ryo had to pay him $500 for information on Yuanda Zhu, and after he dodges his attacks (determinant), Ren will act like he is taking him to Zhu, but instead he takes him to the F Warehouse, only so he could steal the money that was involved in a deal with Yuan and Gangfang Lin and leave Ryo to deal with them. After Ryo chases Ren through Lucky Plaza, he tells him that Zhu is in Kowloon. He only helps Ryo through Kowloon for his own personal greed as he feels there is money involved. He often made Ryo do all the work, and wasn't very helpful. He even cheated when flipping a coin, by having one coin with both sides heads and one with both sides tails so he would always win the bet. However as the story progresses, they begin to develop a friendship. After they defeated Yuan in the Yellow Head Building, Ren dealt with the Yellow Heads and let Ryo head upstairs to rescue Zhu. Also during the fight on the rooftop with Dou Niu, Ren made the fight easier by taking out multiple men in black suits.
- Joy (friend): Ryo first met Joy when he first arrived in Aberdeen, she barged into him riding her motorcycle. Ryo didn't appreciate that, and he shys away from having a romantic relationship with her like he does with all the women he meets. Joy helped him find a place to stay by suggesting the Come Over Guest House and even told him how to get a discount in rent. The day after, she even helped him get a job at Fortune's Pier. Joy gets mad later on, when Ryo doesn't stay at the guest house anymore and when he didn't tell her goodbye when he left for Kowloon. But, he does save her from Master Baihu and their relationship grows.
- Shenhua Ling (traveling companion and confidant): Ryo meets Shenhua after saving her from a river during a storm. She becomes his traveling companion in China, teaching him about nature and showing him the way. They two share a special bond together.
If Ryo fails certain commands; he will die non-canonically and may be given a chance to retry.

- Originally, Shenmue was supposed to be a Virtua Fighter RPG game, so Ryo was originally supposed to be Akira Yuki from Virtua Fighter.
- In Virtua Fighter 5: Final Showdown, Akira can be customized to look similar to Ryo, and also in the offline DLC mode you can fight Akira with a brown leather jacket and blue jeans under the name "RYO".
- In the What's Shenmue? demo, Ryo has the ability to crouch while in free roam by pressing the X button. This was removed in the actual games of the series.
- As seen in beta footage of Shenmue, Ryo was originally supposed to have the ability to travel around Dobuita and Hong Kong with the Push Bike. The feature was likely taken out as Ryo was able to run everywhere faster.
- Yu Suzuki reveals how Ryo got his bandage on a Twitter event called "#YouAskYu". "It didn't appear in Chp.1, but there was a martial arts event. The scar is from the final match."
- Ryo, being Japanese, goes to China and is able to (inexplicably) communicate with everyone in Chinese, even with a villager like Shenhua. When asked about this plot hole, Yu Suzuki simply said, "Let's not go there..." In the first game, Ryo even needs assistance reading Chinese.
- A common joke in the fandom is a theory that Ryo is asexual, "murder-sexual" or "revenge-sexual". He travels around Japan and Hong Kong, all the while being constantly assaulted left and right with female flirtations and innuendos, but almost always ignores them and shows little to no interest back. Even when Nozomi tries to tell Ryo she has a crush on him, he replies, "I... I don't really know how I feel."
- Apparently, according to the Prima Official Guide (non-vertbatim): "It tells you why Ryo is the way he is with girls. Apparantly when he was a kid he used to be a bigshot with the ladies in his school but ended up getting into a fight with someone. This turned him into the guy we know now and he prefers not to get involved as much as he did in his youth."
- In ESPN NFL Football, Ryo is an unlockable free agent player (being #26), along with other Sega characters including Beat from Jet Grind Radio, and Jeffry McWild and Kage Maru from Virtua Fighter.
- Although Ryo was a playable character in Sonic & Sega All-Stars Racing he did not initially return in Sonic & Sega All-Stars Racing Transformed.

Ryo later appeared in the game as a playable character via DLC, but only in the PC version.
- Ryo appears as a character in the tactical role-playing game Project X Zone 2 as a solo unit.
