Jun Yazumi

Jun Yazumi (矢住潤（ヤズミ・ジュン）, Yazumi Jun) is one of the main characters of Ultraman Tiga. He is a member of GUTS.

Personality

As the youngest member of GUTS, Yazumi has an ambitious, enthusiastic, and lively personality. Despite his young age, he can professionally assist the team in logistics and communication support. He can also carry out auxiliary operations with a decisive and calm attitude.

However, Yazumi can also be naive, stubborn, or immature at times. He lacked courage during his first front-line mission and often got confused when facing unexpected events. Despite this, he continues to gain ample growth as a member of GUTS. In his free time, he enjoys computer operations, video games, and writing code.

His only dissatisfaction is that Rena treats him just like her younger brother, not an adult though sometimes he sees her as an older sister figure while addressing her by the honorific 'Onee-chan' (big sister in Japanese).

History

Pre-Ultraman Tiga

Yazumi was born in the Sakuragaoka area. When he was young, he repeatedly failed to learn how to ride a bicycle, feeling regretful. But one day, he stumbled upon a mysterious old woman who encouraged him not to give up and gifted him a pendant with a portrait of a young girl. This event left a lasting impression on Yazumi and remains fresh in his memory today.

Later on, he joined TPC and became a member of GUTS.

Ultraman Tiga

After Ultraman Tiga appeared in the world, Yazumi officially did his duties as a member of GUTS. His main job is to analyze monsters, technology, and materials, as well as research them to gather information. He also uses a system he created called "Akashic Records" to access and search for any kind of data in the world, including not only text data but also images, movies, sounds, and more. He can access it from anywhere. He also seems to be able to access protected TPC databases.

However, due to his role mostly being in the base as logistics and communication support, he was dissatisfied with not being able to participate in front-line actions during the early part of the series. ^{GUTS to the Sky Part 1}

Jun Yazumi 51 — Yazumi feels dazed after witnessing the tragic battlefield.

As the number of monster disasters increased, he advocated for the development of military strength for TPC. Therefore, he had conflicts with those who advocated for peace, like Rena and Mayumi. But after his first front-line battle, witnessing the brutality of the monster Jobarieh and war, he began to rethink the meaning of the human pursuit of power. After re-examining his ideas, he reconciled with Mayumi. ^{One Vanishing Moment}

Jun Yazumi 52 — Yazumi presents Yuri with a necklace

In an event caused by a time-traveling incident, he got appointed by Captain Iruma as the responsible person for a Taisho-era young girl named Yuri who traveled through time. As Yuri missed her hometown, Yazumi decided to take Yuri to find her home and tour the city. During the trip, he gave Yuri a necklace with her photo as a gift and a souvenir.

When Yazumi got called to battle, he witnessed Tiga's fight against Goldras. He realized that if Goldras got destroyed, everything, including Yuri, that got brought from the past to the present would cease to exist. Because not stopping Goldras would cause more damage in the flow of time, Yazumi ultimately said goodbye to Yuri and helped Tiga defeat Goldras.

Later, after returning home, Yazumi went through his old possessions and found the necklace, realizing that the old woman he met when he was young was the elderly Yuri. He was grateful that she was able to return to her own time. ^{The Time-Transcending Smile}

In an opportunity, he and Rena got invited to TOWN to play in an amusement facility. Then along with the strange events that occurred in the facility, he was attacked by Virtual Alien Muzan. He was saved by a mysterious girl while trying to escape. Due to Yazumi's kind actions, the girl gradually developed feelings for him.

However, when Yazumi manages to destroy all the UFOS and the simulated aliens, he discovers that the mastermind behind all of it is the girl. He learned that the girl's true identity was the virtual AI of the biological computer Karen E-90, who controlled the amusement facility and was the programmer behind it. Karen believed that humans were bugs in the world, so she began developing the ability to brainwash humans, create virtual spaces, and invade network systems. Thus Yazumi, who possessed anti-hacker skills, was viewed as a target.

Due to her feelings for Yazumi, she had once persuaded Yazumi to live in the world she created together. After being rejected by Yazumi, Karen became Faivas in anger and disappointment and invaded the computer systems of the GUTS base in an attempt to attack Tokyo. In the end, after Yazumi's persuasion and an effort to express his feelings, Faivas ultimately gave up resistance and willingly allowed herself to get deleted by Tiga. She thanked Yazumi before disappearing. ^{Town Where the Girl Disappeared}

Before Gatanothor's resurrection and the destruction of the world, he, along with GUTS and TPU's senior staff, witnessed Tiga's defeat and learned the truth about Tiga's identity as Daigo. They then put all their efforts into a rescue plan, trying to revive Tiga, who had become a statue. ^{Master of Darkness}

After learning that Captain Iruma and the TPC investigation team lost contact on R'lyeh, in order not to worry about Daigo and Rena, who were about to get married, he and Mayumi meet them both and travel together. After learning that the incident was getting out of hand, he and the members of GUTS went to R'lyeh to support operations.

In the end, he and everyone witnessed the return of Glitter Tiga and the submergence of R'lyeh.

A year later, he and the other members bid farewell to Daigo and Rena, who were heading to Mars. ^{Ultraman Tiga: The Final Odyssey}

With the disbandment of GUTS, Yazumi was sent to Jupiter's Ganymede base as the program director of the base's comprehensive computer technology agency, mainly focusing on weapon development issues at the base and assisting in the construction of space battleships.

Before the final battle against the Spheres, he assisted Super GUTS and Dyna in stopping the action of the Super Synthetic Monster Neo Gaigaraid. Despite the approaching darkness brought by Neo Gaigaraid, he calmly completed his work and finally evacuated the base with Dr. Kisaragi, who assisted him. ^{Final Chapter II: Solar System Annihilation}
