Digimon Seekers
When Yulin was a teenager, she once got confused by the police as a middle schooler and was escorted home since she was considered to be out to late for a girl supposedly so young.

During her time at University, Yulin studied and worked under Tomonori Ryusenji. Ryusenji Laboratories was able to vault to the forefront of Digital World research shortly after its discovery due to the hard work of Tomonori's students: Yulin, Kosuke Kisakata, and Saya Ryusenji.

One day, when Yulin arrived at Ryusenji Laboratories and delivered the mail to the professor, who was busy analyzing some code. He complains about the code itself being awful, expressing shock that it was probably written by Ryusenji himself. As they discuss Yulin's request for a proper server room, the campus being transferred to Denrin, and the new investments in their field around the world, Ryusenji lets her know that since the campus was going to be moved, all requests such as the server room were rejected since it'd be seen as a waste of money. Yulin questions if they will have to go overseas, prompting an annoyed response by Kosuke, who once again had slept in the office. As Yulin calls him out for his habits, Saya arrives with food for everyone and a change of clothes for Kosuke.

As the group eat the food Saya had brought them, Yulin scolds Saya for coddling Kosuke too much though she fires back about how she is now his wife and not his mother. Tomonori laughs at the group's interactions, with the group moving on to talk about their research. Since Digimon didn't live very long, research wasn't going well and they figured they needed to find a way to breed and raise their own Digimon to make studying them easier. Saya mentions that if they really are living creatures they could raise them like pets, though Yulin points out she didn't feel that way herself. As they muse that extra-terrestrial life was actually on the Internet the whole time Tomonori laments that they will need money to be able to continue their research — something everyone is able to agree to. Fully devoted to this cause, Tomonori announces that he is going to start a company and as they doubt his ability to Kosuke brings up that the University had money set aside for start up companies which they should be able to use for this end if they were able to convince them to back the project. They decide Yulin should make the pitch since she was trilingual and good at presentations but Yulin herself was worried someone with Chinese ancestry doing so would ruin the entire plan. She winds up agreeing to do so as the others let her know that it didn't matter and she was the only one who could do it.

Some time later, having found a new office, Ryusenji Laboratories prepared to start their move. Kosuke tells the others the they wont see much of him as he would be "fighting on the front lines", with Saya disappointed with the fact he didn't have enough credits to graduate yet. Kosuke muses that it doesn't really matter as he doesn't mind staying at the University for a few more years with Tomonori saying he will hire him regardless of if he graduates. Saya protests, saying that's not something a professor should say — but he simply laughs saying maybe she's right.

Tomonori and his students were able to get permission to use a warehouse within the Denrin District as a temporary base for their work despite the fact it was going to be destroyed for redevelopment soon. The group redecorate and replace the name plates with it acting as the headquarters for not just the University but Ryusenji Electrics as well. Tomonori was very happy, since he was now running his own business — even with the massive debts he had incurred setting it up. They had managed to set it up with a mix of University funds, money from the government, and Tomonori's own money — the biggest amount coming from Tomonori himself. Now they had managed to set things up, the group were ready to use Digimon to unlock something significant for humanity.

Some time later, Ryusenji shows off the fruits of his labor — the Digimon Dock. He intended to use it to record the actions of the Digimon, though none of his students were impressed with it. Since the Digimon die fast on their computers, he wondered if he could recreate their habitat as closely as possible within something else — hoping the Dock would be able to help with that. He decided to make it a toy, as he wanted children all over the World to be able to become friends with Digimon. When he refers to the Digimon as humanity’s irreplaceable companions, Yulin becomes enamoured with the idea and when Saya notices this she gives her a Digimon Dock. Yulin is surprised to see a Digitama on it, with Saya and Tomonori explaining they had found it on the Internet and that the Dock was able to display the data itself instead of as a series of numbers like on their computers. The group are amazed at the sight, and become even more excited when the Digitama begins to move. Thinking it was going to hatch, Tomonori snatches it out of their hands as he wanted to see.

Tomonori was promoted to being a full time professor at the University. In addition, a big tech company invested so much money in his work it allowed Ryusenji Electronics to become a proper business. Tomonori was able to hire more staff and as the company got bigger they realized they needed to move on from the rented warehouse.

Saya and Yulin discuss and celebrate the fact that Kosuke had proposed to her. They then discuss the new employees at Ryusenji Electronics and the fact that the company would need to go public to pay back their investors since thus far they hadn't actually made any money. Kosuke joins the conversation, joking that Yulin was trying to steal Sara from him, and shows off a VR headset. He puts it onto Saya's head and tells her that she is currently seeing through a Digimon's eyes and can see what it can see — though it was a recording rather than live.

Wanting to one day explore the Digital World, Tomonori continues to work even harder. Wanting to experience all five senses whilst there, he began researching DigiCores in the hopes he could transfer human consciousness into it and allow his goal to come true. He found it was possible too, as other scientists were researching ways to convert the human consciousness and memories into data. There were even machines that would allow blind people to access sight, or deaf people to access hearing though the government had made it so that they couldn't move past research for around 10-20 years. Tomonori figured however, that since the Digital World was a different World, those rules wouldn't apply which lead him to focus his time on this endeavour and would focus on it even if it took him the rest of his life. To make sure no one would find out and stop him, the company researched it in secret.

Some time later, Saya would become the first person to do a Mindlink — linking her mind with a Digimon — though the effects on her body were bad with her vomiting and defecating herself in front of everyone. As she did more and more Mindlinks her body got used to it and the side effects would be less severe. Upon coming too, she looks into her Digimon Dock and praises her for its hard work. Yulin and Kosuke had also been given their own Digimon partners, with Kosuke's turning his life around since he had to make sure he was able to properly look after.

All three of them would go through many Mindlink tests though thus far had only explored their Digimon Docks. To be able to explore further than that, and reach the Digital World, they would need better computers. They would also need to learn how to control their partners, since if they lost control they would go passed the Mindlink limit and be unable to return to their bodies. As they discuss these facts, they also theorize what the Digital World would actually be like.

Kosuke was in charge of the development of the Digimon tools and would send Digimon out to the Digital World to explore. Around 80% of the Digimon would return alive, giving them lots of useful information. Tomonori muses that it would be impossible for such tests to be 100% successful, comparing it to space mission in the past — this making the students uncomfortable since he brought up instances of astronauts failing to come back especially since they would soon be joining the Digimon on their travels via Mindlinking. They would refer to said upcoming Mindlinking project as the Tartarus program.

The night before beginning the Tartarus program Yulin, Saya, and Kosuke visit the plot of land on which Tokyo University of Electrical and Computer Engineering was to be built in the Denrin District and look on in amazement that such University was going to be built there. As they take in view of its current appearance, before the building would be made, Saya makes a wish that everyone would still be together in ten years — including their Digimon partners. She shows off the area to her, by pointing her Digimon Dock at it, and makes another wish that the Digimon will be able to live alongside the humans. Yulin is confused at the fact Saya was talking to her Agumon, since they can't talk back, but she tells them that Agumon had actually been talking to her during their Mindlinks — a fact that shocked Yulin. Realizing what she had said, she tells Yulin not to tell anyone as she was scared she would be seen as crazy and be removed from the project. She tells her that Agumon would call out her name and tell her she's glad she came to play and this leads Yulin to think Digimon might actually be dangerous and that they were actually the ones discovering humans, not the other way round. Saya points out it was too late now though, and that their Worlds were now destined to collide. She also tells Yulin she is considered the most important member of the team as Saya was Tomonori's daughter and Kosuke was just a younger version of him. In addition, she was considered to be the only one to be to stop them should they mess up. Kosuke joins them, giving them warm drinks, and though he tries to get them to leave due to the weather Saya insists they stay longer. Yulin leaves, returning to the car to warm up, and with the couple now on their own, they act like love birds which irritates Yulin and causes her to take a picture of them.

The next day, Yulin, Kosuke, and Saya Mindlink to their partners. They have their partners board the Tartarus probe, a digital observation vessel so that they could begin the Tartarus program. The Digimon search the Digital World on their own virtual vessels with their partners controlling the vessels using Kosuke Kisakata tools. Due to the weak technology being used, the groups visibility was low but despite this they followed the path set for them and continued on their journey. As they explored, they were attacked with Kosuke and Yulin having no clue what had attacked them. Yulin and Kosuke figure Agumon had been the attack target, and were unable to do anything as Saya's unit vanished without a trace. Kosuke blamed himself, as he had been the one to push for her to be a one woman rescue team, and regretted it wishing he had been doing it instead so that she would've returned safe in place of him. Tomonori forces Kosuke and Yulin to retreat as he considered it far too dangerous to have them try and rescue his daughter. The Tartarus probe was damaged and and Tentomon were injured and as such he had them withdraw as the chance of all three of them falling into DMIA was too high. When they logged out, Kosuke cried as he held his unresponsive fiancée. Her consciousness had fused with Agumon's DigiCore, and Agumon's whereabouts was unknown. Now in a coma, her body was sent to the local hospital with no hopes of her ever waking up.

Over the following years, Tomonori made sure to keep Saya's body in a stable condition. He sent her to a hospital in the United States that specialized in coma patients then continued the Tartarus program and Mindlink tests in secret — though without the help of Yulin and Kosuke as he didn't want to put them in any more danger. Despite losing Saya, most aware of what happened considered the project a success as they had managed to capture footage of the Digital World and their programs allowing control of their Digimon worked as intended. Yulin and Kosuke didn't feel this way though, and considered it a failure. Kosuke cut contact with Yulin, and dropped out of University — though still kept in contact with Tomonori.

Many years later, and the Digimon Dock was a success. Many people had befriended and raised Digimon and and it did indeed allow them to live longer. More and more sponsors poured money into Tomonori's research and with more money, Tomonori was able to increase his influence within the University. The extra money also allowed the University itself continued to grow.

Yulin eventually start working for the DigiPolice, one day becoming its chief.

Even when working for the DigiPolice, Yulin visited Tomonori often.

When Satsuki Tamahime reports to Yulin about her battle with Eiji Nagasumi and Yulin is surprised at how powerful Loogamon was, despite being at the Rookie level, and is also surprised that Eiji's name wasn't listed among the top executives of the Sons of Chaos with how powerful he was. She praises Satsuki for somehow figuring out his real name though is less impressed upon learning he had simply told her for seemingly no reason. She berates Satsuki for going passed the Mindlink limit once again and tells her that doing so risks death and that she needs to stop doing it as she doesn't want any member of the DigiPolice to die. Satsuki apologizes though Yulin ignores her and opens up the file on Eiji to learn more about his life. Within the file was a recent video of him in the real world outside the Tokyo University of Electrical and Computer Engineering with this surprising Yulin, since he wasn't a student there. Yulin notices something and tells Satsuki to zoom in on Eiji's arm with them doing so revealing he owned a Digimon Linker. Ryudamon hololizes within the office to watch the video as well which causes Yulin to compare Loogamon and Ryudamon. This has her notice they have similar interfaces on their heads.

Yulin attends a meeting with Tomonori, walking passed Eiji on the way there as he was coming out of Tomonori's office. As they walk passed each other, she looks at him — fully aware of who he was.

The DigiPolice later fight some code crackers during a patrol. After a Mindlinked Yulin/ capture some of the Digimon, Hisyaryumon analyzes them and deduces they were foreigners after state secrets. Though warned by Hisyaryumon that interfering in foreign affairs was against the law, Yulin decided she would still deal with it since what happens to them wouldn't matter once they returned home. As she looks at Hisyaryumon, Yulin reminisces about her past and wonders what Kosuke and were up to — Hisyaryumon interface reminding her of Dorumon.

Yulin vists Abadin Electronics and whilst in their buildings and thought back to the failed Tartarus program missing. She tries to remember the last time she saw Kosuke, and thinks back to if it was when she saw him visit Saya in the local hospital right after the incident. As she thinks about Kosuke, her thoughts are interrupted by three spheres labelled Data, Vaccine, and Virus.
