Hikari Tachibana – Blue Archive Character Profile

During the Trans-Desert Railway dispute, Hikari and Nozomi press forward without the proper permission, are confronted by the Abydos Foreclosure Task Force, and lose the ensuing clash. Their overseer Suou arrives to take custody of them, making clear that the twins’ recklessness is not a unified Highlander policy. Hikari’s apparent lack of concern does not erase the very real danger their actions create.

Later, Kaiser PMC attacks the railway area and the twins find themselves surrounded. The Abydos students rescue the Highlander group despite their earlier conflict. Hikari and Nozomi subsequently return the favor by providing a fast train when Sensei and the Task Force need to pursue a dangerous target along the railway.

With Kaiser forces pursuing them by train, the sisters arrange for their passengers to escape and use a spectacular maneuver Hikari calls 'Train Drift' to stop the pursuers. The train is wrecked; the twins then surrender to Kaiser rather than trying to win a direct fight. Their help lets the Abydos group continue toward its destination, turning an earlier confrontation into a practical act of cooperation.

Hikari and Nozomi appear again as the effort to intercept the Train Cannon reaches its climax, assisting the Task Force’s approach. Hikari’s reaction is characteristically peculiar: the prospect of destroying a train is distressing to someone so devoted to them, even in a crisis.

In the short Highlander Railroad Academy Operation Log, Hikari and Nozomi are contacted as trouble overwhelms a train crew on the HL9000 inner-loop service. Unable to respond immediately, the twins advise the staff to avoid overexertion and prioritize safety. By the time they arrive, the three crew members have suppressed the disorder through armed resistance, leaving the cars heavily damaged. The twins nevertheless praise the crew’s initiative and recognize them as outstanding students for the month. Their response illustrates the CCC’s unusual workplace culture as vividly as any high-speed stunt.

In Highlander Railroad Runaway Incident: And the Train Disappeared, Hikari and Nozomi are assigned a freight delivery with Utsumi Aoba, a mechanic from Highlander's Cargo Transportation Management Department. They postpone departure to relax and eat pizza, to Aoba's dismay. By the time they return to work, the train has vanished, and what should have been an ordinary transport assignment becomes a pursuit across Kivotos.

A system malfunction sends the freight train away without its crew. Hikari and her companions chase it first by subway and then by bus with Sensei's help. Hikari finds its location using a communicator, but an exchange about holding the train at a station is overheard by Kronos reporters. Their broadcast attracts biker gangs and other opportunists to its apparently valuable cargo. Neither twin knows exactly what is aboard; their immediate aim is to complete the delivery.

When the train's brakes fail, Aoba devises a desperate solution: explosives remove the locomotive's wheels so the train can be brought to a destructive stop. The group still must fend off attackers at the destination. Their supposedly mysterious cargo turns out to be goods intended for a charity auction, and the shipment is delivered despite the wrecked locomotive. The ordeal ends with the Highlander students and Sensei heading out for dinner, an improbably ordinary finish to Hikari's chaotic assignment.

In Hikari's relationship episodes, she visits or summons Sensei to spend time together when her work is done. Her fondness for sweets eventually gives her a painful toothache. Sensei stays with her through dental treatment; afterward, Hikari tries replacing sweets with extremely spicy food, only to decide that she would rather brush her teeth properly. An unexpectedly everyday problem punctures her carefree confidence.
