==History==
===Ultraman Orb THE ORIGIN SAGA===
When first introduced, Yui and Shohei were in the midst of conducting a submarine exploration mission. They were exploring the mysterious ruins of an ancient civilization located 4,000 meters deep in the Sea of Japan. During this expedition, they stumbled upon a mysterious seed within the ruins.
Upon bringing this seed back to the surface, Yui and Shohei commenced their study of it, confirming its origin from an ancient civilization through radiocarbon dating. Yui was taken aback by the seed's continued vitality and size. However, during their conversation, she noticed that Shohei unconsciously shed tears.
Subsequently, with the discovery of inscriptions on the ruins, Yosuke Aoi speculated that the depicted entity might be the World Tree. He described how its branches extended endlessly, its trunk connected the past and the future, and its fruits could bestow infinite life. Yui, on the other hand, found the concept of "eternal life" exceedingly boring and unnecessary, considering the idea of getting trapped deeper and deeper as terrifying. However, as Shohei's concern for the seed escalated to an obsession, he was forcefully propelled backward by a powerful resonance when he observed the seed. Astonished, Yui and Aoi rushed him to the hospital for treatment after witnessing this event.
While Shohei rested in his hospital room, Yui and Aoi informed the doctor about Shohei's condition. The doctor inquired whether Shohei had been in contact with anything unusual and suggested that it might be symptoms of bacteria or parasites affecting the brain. Yui, curious about the possibility of bacteria attached to ancient artifacts, posed a question, which Aoi skillfully evaded with an analogy.
Upon returning to the hospital room, they were surprised to find Shohei creating an unusual scene of the Tree of Life using ink on the bedsheet. Yui was alarmed by his behavior and learned about the existence of Planet Kanon and Amate. Despite her concern for Shohei's mental state, Yui chose to continue listening and expressed her commitment to be by his side.
After several examinations by the doctor, Yui learned that Shohei's brain and nervous system showed no abnormalities, suggesting that his issues were likely psychological. After his discharge from the hospital, despite Yui's continuous concern, Shohei exhibited more abnormal behavior and lapsed into a coma once again.
Upon waking from his coma, Shohei informed Yui about the felling of the Tree of Life. What neither of them knew was that the seed in their research laboratory was, in fact, the Tree of Life. When the Tree of Life on Planet Kanon was felled, the seed on Earth began to sprout, and as they hurried back to the research institute, they witnessed the rapid growth of the Tree of Life.
During the evacuation process, the two of them found themselves trapped inside a building, unable to evade the situation. In their moment of desperation, a man named Gamu Takayama, guided by Earth's consciousness from another world, came to their rescue just in time. After comprehending the entire situation, they had their first encounter with Gai, who had been dispatched to Earth by Amate.
Following a comprehensive examination by Gamu, Yui finally learned that Shohei's pineal gland had undergone evolution, enabling him to establish a connection with Amate. This connection achieved the seemingly impossible, confirming the pivotal role of the Tree of Life in advancing the intelligence of living beings. However, Yui was skeptical of the grounds for the Tree of Life's growth driven by the connection between Amate and Shohei, questioning Gamu's use of the term "miracle" and insisting that scientists would not describe it as such. 
Nevertheless, Gamu believed that the world was filled with unexplainable phenomena that could be termed "miracles" because they transcended the scope of scientific understanding. Similarly, Gai emphasized that these events were fueled by the power of "love" and highlighted the concept of "miracles created by love." This left Yui, who had long harbored feelings for Shohei, with some inner turmoil.
The following day, news reports in Japan began to cover the appearance of the Tree of Life in Tokyo. Shohei, anxious about Amate's warning, attempted to urge Aoi and other team members investigating the tree to evacuate. Yui tried to stop Shohei, but she witnessed the moment when Bezelb, who had arrived on Earth, captured him. Fortunately, with the assistance of Ultraman Gaia and Ultraman Orb, they successfully rescued Shohei.
Through real-time news reports, Yui and the others learned that the Japanese government's Cabinet meeting had decided to issue an emergency evacuation order for the residents of Tokyo under the Emergency Disaster Measures Act. The JSDF had proceeded with the next step of their plan to destroy the Tree of Life. Just at that moment, Shohei once again sensed the news of Amate's arrival on Earth. Yui could only watch alongside the others as Shohei and Amate met and embraced each other in an emotional reunion.
Upon learning about the existence of Queen Bezelb, Yui and the others witnessed Shohei and Amate attempting to establish contact with Queen Bezelb through a resonance phenomenon. They saw Amate transform into the War Deity in an attempt to initiate a formal dialogue with Queen Bezelb. However, this contact turned out to be a trap set by Queen Bezelb herself. Her true intention was to inject a highly concentrated puppet toxin into the War Deity, causing her to explode and disseminate the toxin to various corners of the universe, thus disrupting wisdom.
Upon witnessing the War Deity being controlled, Yui and the others made the decision to rescue Amate from the grip of the toxin. During this endeavor, they glimpsed visions projected across the entire universe by the War Deity, revealing the worlds devastated by Queen Bezelb. These revelations deeply unsettled Yui.
Ultimately, they found another seed in the underwater temple and attempted to implant it into the War Deity's head to halt her destructive behavior. However, due to the incomplete structure of the seed, they were unable to successfully stop the War Deity's rampage.
Despite experiencing failure, upon witnessing the Tree of Life bearing fruit, Yui made the decision to accompany Shohei on a journey to the top of the Tree in search of seeds. However, when they found the fruits, they discovered that these fruits had not fully ripened and showed no signs of illumination. Just when Shohei was on the brink of despair, Yui offered him words of encouragement, urging him not to succumb to despair at this stage. It was precisely because of the connection between Shohei and Amate, which led to the miracle of their hearts communicating, that despair was even more unwarranted.
In the midst of fervent prayer, Yui ultimately witnessed the extraordinary connection between Shohei and Amate's consciousness, causing all the fruits of the Tree of Life to blossom with the hope of life. This connection successfully freed War Deity from the grip of the toxin.
After the victories of the five Ultras, the Tree of Life on Earth was preserved. Amate returned to her original state and reunited with Yui and the others. She expressed special gratitude for the efforts of Yui and Shohei, acknowledging that striving for a conflict-free world in the current universe was indeed a challenge. However, as long as hope was not abandoned, this ideal would one day be realized. As long as wisdom existed, a world filled with love would never come to an end.
