Rin Natsume

is the investigator and genius programmer of the Hoshimoto City Branch of SKIP.
==History==
===Pre-Ultraman Arc===
In the past, due to her parents' work, Rin frequently moved from place to place during her childhood. Among the many cities she lived in, Hoshimoto City was her favorite. This is why Rin chose to settle there after reaching adulthood.
After coming of age, Rin Natsume became an investigator and programmer at the SKIP Hoshimoto City branch. As a brilliant programmer, she is highly proficient with mechanics and responsible for maintaining systems and developing equipment at the institute. In addition to her mechanical engineering skills, she took charge of developing the AI robot "YouPi" from the beginning, forming a trustful sibling-like relationship with it.
As Yuma's senior, Rin has a cheerful and straightforward personality, and she demonstrates a strong sense of professional dedication. On Yuma's first day of work, she attentively helps him adjust to his role as an investigator at SKIP. During a break, she inquires about Yuma's past and is deeply moved by his traumatic experiences and unwavering spirit, offering him encouragement with a friendly and supportive attitude.
When Digelos appears, Yuma falls into panic due to his past trauma. Rin calmly intervenes to help him regain his composure, and together they participate in the evacuation of citizens. During this process, she, along with Bin, witnesses the "Giant of Light" that Yuma had mentioned.
===Ultraman Arc===
In her debut, Rin was investigating "Monohorn" with Hiroshi Ban on Mt. Shishio, the horn of the Monogelos that appeared during the "K-DAY" incident. Using their detectors, they discovered a mysterious creature inside Monohorn — "Oo-ze." Oo-Ze then burrowed underground and parasitized the armored kaiju Shagong.
With assistance from GDF investigator Shu Ishido, the team analyzed Oo-Ze and found that Shagong, now parasitized, was forced to ingest Oo-Ze's nutrient source, calcium carbonate, mutating into a giant kaiju nearly 50 meters tall. It began moving towards Hayama Chemical Industries in Hoshimoto City, prompting her to join the evacuation efforts on site. She witnessed the entire battle between Ultraman Arc and Shagong. The next day, she joined the other members in welcoming Shu as he joined the team as a Special Investigator.
A few weeks later, Rin and Yuma went to she favorite, friendly neighborhood shopping street to buy lunch. However, the shopkeepers reported that some strange incidents had occurred recently. Evidence from the store’s power system damage suggested it might have been caused by rats, but these were not ordinary rats. The shopkeepers requested Rin’s help. Although Rin initially thought the case might not involve kaiju, it turned out that these rats were nearly the size of humans and their target was not food, but the power system.
It was reported that a certain university had discovered a new species of rat, named Electricamus nipponicus, which carries a unique bacteria. These rats seemed to be spreading and multiplying in Hoshimoto City. As SKIP's investigation progressed, Rin, Yuma, and YouPi suspected that these rats might be hiding in the Kawami Heavy Industries factory that supplies electricity to Hoshimoto City. The factory uses a highly explosive mineral called "daimode" as energy for its generators. After obtaining permission for the investigation, Rin and Hasegawa from the factory’s public relations department discovered a giant rat the size of a human in the laboratory.
The giant rat attempted to attack Rin, but as it tried to escape after Rin fired the Compact Launcher, it was electrocuted when it crashed into the generator. The electric shock caused the giant rat to merge with other rats, transforming into a 50-meter-tall kaiju: Nezutron. Nezutron absorbed daimode energy from the generator through cables connected to its body, putting the city at risk of disaster.
Due to the excessive absorption of daimode, which could lead to a high-intensity explosion, Rin and YouPi ventured back to the base to find a way to shut down the generator. YouPi accessed the Kawami Heavy Industries system and discovered that the generator's temperature was continuously rising. Rin successfully managed to stop the generator, which caused Nezutron’s discharging abilities and electromagnetic shield to disappear, giving Ultraman Arc an advantage in the battle.
After leaving the factory, Rin, YouPi, and the factory staff cheered for the struggling Ultraman Arc and witnessed Arc don the Solis Armor and defeat Nezutron. Afterwards, Rin sent a report of the incident to headquarters and reunited with friends from the shopping street.
