Nozomi Tachibana橘ノゾミ

First-year Highlander Railroad Academy student and Central Control Center officer

Nozomi Tachibana is a first-year student at Highlander Railroad Academy in the video game Blue Archive. She is an officer of the school’s Central Control Center (CCC), where she works alongside Hikari, her older twin sister. Nozomi is lively, mischievous, and quick to leap into whatever looks interesting; she also loves setting new speed records.

For all the trouble the twins cause, she takes her duties in train operations seriously—a responsibility that becomes central to her appearances in the story.

Biography

A mischievous officer at Highlander

At Highlander Railroad Academy, trains are more than a background detail: managing rail service is part of the school’s work. Nozomi is only in her first year, yet she and Hikari hold officer positions in its Central Control Center. The twins are eager to try entertaining ideas and are prone to creating trouble, but Nozomi’s student profile makes an important distinction: she does not take the actual operation of trains lightly.

Speed, work, and the Tachibana twins

Breaking speed records is Nozomi’s stated hobby. Her appetite for excitement is evident in the way she approaches railway work, where the urge to go faster sits beside an obligation to finish the job. She and Hikari become involved in the railway dispute surrounding Abydos in the main story. Highlander’s day-to-day operations also feature in a separate mini-story, and the sisters later take center stage in a freight-train event.

A brief look at the CCC on an ordinary day

In a Highlander operations mini-story, a train crew calls the CCC as disorder spreads through the carriages. Nozomi and Hikari cannot respond immediately, so they advise the crew to put safety first. The incident gives a glimpse of their supervisory duties beyond the twins’ better-known adventures.

Personality and Motivations

Nozomi is energetic and unrestrained, with a habit of charging toward anything that promises excitement. She does not dwell on small details and can be a handful for colleagues trying to keep a quiet, orderly workplace. Her attitude changes when an actual railway assignment is at stake: responsibility for a train’s operation matters to her, even if she rarely sounds solemn about it.

With Hikari beside her, Nozomi’s mischief often becomes a two-person enterprise. The sisters’ irreverence can frustrate more cautious coworkers, particularly mechanic Aoba, yet the freight-train story also shows Nozomi refusing to abandon a delivery simply because it becomes difficult. Her comic recklessness and her professional pride coexist rather than canceling each other out.

Appearance

Nozomi has pale-green hair gathered into long twin tails, yellow-gold eyes, pointed ears, and a glowing halo. She wears a dark navy Highlander railway-style uniform with blue and gold accents, white gloves, and a peaked cap marked with a badge. The outfit is recognizable in her game illustration and in the officially licensed Nendoroid design.

Abilities

Railway operations and train driving

Nozomi helps oversee rail operations as a CCC officer and has notable train-driving ability. She enjoys pursuing higher speeds, while her official profile specifically emphasizes her responsibility for keeping trains operating.

Handgun combat

Nozomi carries a handgun called Dead Girl’s Switch. In gameplay she is a Sonic-damage Striker/Attacker, and her EX skill, Booster ON!!!, hits a selected enemy and other enemies in a straight-line area; spending up to two additional units of skill cost increases its damage.

Limitations: The stronger EX attack requires additional skill cost, up to the two-unit limit; this is a gameplay mechanic, not a claim of limitless power in the story.

Relationships

Hikari Tachibana

Older twin sister and fellow CCC officer

Hikari is Nozomi’s older twin sister. The two work together at Highlander, sharing an irrepressible taste for excitement and frequently landing in trouble together.

Utsumi Aoba

Railway maintenance colleague

Aoba, a railway mechanic, works with Nozomi and Hikari on a freight assignment. Her more anxious, methodical approach provides a sharp contrast to the twins’ casual attitude.

Sensei

Adult adviser and collaborator

Sensei becomes involved in Nozomi’s Highlander railway assignments, helping her and her colleagues navigate trouble during a freight-transport incident.

Interesting facts

Nozomi debuted in the main story’s Abydos-focused Volume 1, Chapter 3 before she became a playable student.

Her story introduction and playable debut happened at different points in the game’s release history.

Nozomi and Hikari appeared as limited 3-star recruitment characters on the global server beginning September 23, 2025.

Their playable release was tied to the Highlander railway event rather than to their first narrative appearance.

The official global update added special individual and joint cafe interactions for Nozomi and Hikari with the Choo Choo Mini Train.

It is a concrete game detail that emphasizes how closely the sisters are presented as a pair.

Nozomi’s personal handgun is maintained even though her character description says she rarely has cause to use it.

Her equipment description connects combat readiness to protecting railway schedules rather than making gunfighting her central hobby.

Before the twins’ names were widely known, fans called Nozomi and Hikari “Shupogaki”; the term is a fan nickname, not an official character title.

It explains a common name readers may encounter while keeping it separate from Nozomi’s canonical identity.

The Abydos railway dispute

In Volume 1, Chapter 3, Nozomi and Hikari become involved in a dispute over the desert-crossing railway through Abydos. The line’s ownership and redevelopment are contested, and the twins appear on Highlander’s side. During the confrontation with the Foreclosure Task Force, they maneuver a train onto an adjacent track to block their opponents before Highlander supervisor Suou intervenes and defuses the immediate clash.

As the conflict escalates around the Shemata railway gun and Hoshino’s departure, the sisters assist the Abydos students in pursuing Hoshino and Suou. They arrange fast rail transport and help delay Kaiser forces. Later, they are shown participating in work to restore the damaged railway line. These actions turn their first clash with Abydos into a more complicated working relationship.

An unruly train and the CCC’s response

In the Highlander operations mini-story, the crew of circular service HL9000 faces a succession of disturbances. Nozomi and Hikari initially advise the overwhelmed students to stay safe because the CCC cannot arrive immediately. The crew eventually drives off the troublemakers with gunfire, badly damaging the cars in the process. When the twins see the aftermath, they praise the crew’s response and name the students outstanding performers for the month—an absurdly generous assessment of a battered train.

When the freight train disappears

In Highlander Railroad Runaway Incident: And the Train Disappeared, Nozomi and Hikari receive a freight assignment with mechanic Utsumi Aoba. After an argument with a pizza-delivery crew, they discover that a system malfunction has sent the cargo train away without them. The twins enlist Sensei and pursue it by subway and bus. At an intermediate station, Hikari radios ahead to have the train held, but the warning reaches a station where a news team is present. Coverage of the supposedly valuable cargo attracts opportunists who attempt to seize it.

A delivery worth finishing

After the group boards the freight train, attackers pursue it and further trouble breaks out as it crosses into Gehenna. When Aoba worries that the mysterious shipment might involve wrongdoing, Nozomi insists that the task they accepted is to deliver it; uncertainty about its contents does not erase that responsibility. The train’s brakes then fail, and Aoba devises a dangerous emergency stop using explosives left by the attackers. The cargo reaches its destination despite severe damage to the train and railway. Its owner turns out to be a philanthropist, and the shipment consists of items for a charity auction supporting students. The episode closes with Sensei, the twins, and Aoba going to dinner together.

Additional story facts

During the missing-train incident, Nozomi insists on distinguishing the team’s duty to deliver cargo from its uncertainty about the cargo’s provenance.

It is a pointed example of her work ethic interrupting her otherwise carefree manner.

After their confrontation in the Abydos railway dispute, Nozomi and Hikari help the Foreclosure Task Force pursue Hoshino and Suou. Their assistance follows the defusing of the earlier clash; they provide rapid rail transport and help hold off Kaiser forces.
