== Biography ==
=== Childhood and early career ===
Keiko Hirano was born on April 21, 2521 to doctors Asuka and Takeshi Hirano in Hat Yai living in a small town where she would see them perform their work on the local townsfolk. She also started reading books regarding the human anatomy in her childhood and often did surgery on her stuffed doll named Margu with efficiency resulting in her father realizing she would one day continue the family business. The Covenant soon invaded the planet with her mother and father helping the troops heal who passed by and packing their things to leave the place, the evacuation started normal with the family being on board a cargo truck bound for a civilian shuttle as her mother planned to live with her rich brother on Earth in Japan until a spec-ops team ambushed them killing all of the defenses around them as her father defended her by using his body for cover although he died from his injuries alongside her mother. When the team walked away, Keiko was found by an injured Jiralhanae resting while she helped patch a wound on his foot much to his shock that a human saved him with the little girl explaining that her father told her that the universe is a home and that everyone should share it.
The brute asked Keiko where she was going and it was a civilian shuttle resulting in the alien taking her there by letting her ride on his shoulders telling her stories of his home world. He soon arrived in the evacuation area where he made his presence known by walking into a panicked crowd of civilians and gave her to a stunned UNSC colonel saying they'll keep her safe before he surrendered himself to them. Keiko was soon put into the refugee program and met Kurt Ambrose and listened to his speech about taking revenge on the Covenant to whom Keiko signed up for.
Kurt noted Keiko's skills as a trainee being on par with everyone else's but what made her stand out was indeed her medical prowess while known to come back for trainees who faltered and would share her teammates burden. She was soon given her augmentations and conducted mainly rescue operations even one where she saved an injured Unggoy.
=== Fall of Reach ===
Keiko was among the many Spartans deployed on Reach in charge of civilian evacuations in New Alexandria and conducted another rescue operation with the help of some ODST's along the way. A Covenant team occupied an entire apartment as the team consisting of her and marines rappelled down using silenced weapons to kill every single Covenant inside before the Sangheili commander took a family hostage to whom Keiko pretended to surrender letting a marine sniper kill him. She and a couple of volunteers let the civilians in trucks after command lost contact with them only for the last shuttle to leave prompting them to drive out of the city on ground. While driving away from Alexandra prior to its glassing, the convoy was attacked by a Banshee to which they all halted as the ship shot at them killing a majority of the marines and ODST's guarding them but Keiko destroyed the ship using a Spartan laser.
The party soon diminished leaving Keiko and some marines as a last line of defense with paranoia mounting between them while some accused each other of stealing. One night, one of the marines seemingly detected something in the bushes making them act upon it in response, the bushes began to move aggressively causing them to fire upon at whatever was moving with Keiko joining in only to hear a baby crying prompting Keiko to go to the bushes revealing they just shot two civilians who were carrying a baby. An enraged Keiko turned to the marine who started it then punched him in the stomach while another picked up the baby to take care of and gave to another marine. Keiko searched the dead civilian and found a radio talking about a ship called the Valhalla and that they were picking up civilians, UNSC personnel or anyone that was left behind on Reach. She and the others made it in time and met Rosenda-A344, Diego-A112, Imogene-B078, Harry-A299, and Riley-B019 who were among the Spartans that evacuated. When a Covenant scouting party found them, the group was tasked to destroy their backup in the form of an incoming cruiser to which they obliged using a captured Phantom. Due to Rosenda's skills with the Sangheili language-the infiltration was a success and they boarded the ship where they used it's weapons against the scouting party due to Imogene's knowledge then planted a HAVOK nuke before leaving.
The Valhalla's drive was soon damaged leaving it adrift where the survivors were put into stasis with Keiko among them.
=== Recovery and integration to the Spartan-IV Program ===
Keiko was among the Spartans awakened by a crew of a cruise ship that was in space after one of them turned off the stasis. She was later integrated into the Spartan-IV Program and was efficient with her medical skills albeit having antisocial habits with her fellow Spartans even interacted with Blue team. Keiko was soon put into the new incarnation of Noble Team due to her skills as a medic on the field.
=== Operation: HIGH NOON ===
Keiko and the rest of Noble team were deployed in a small town in Montana after Insurrectionists took over the place with the only evidence posted online where ONI found it. She was part of Rosenda's plan to split the team to take the other two regions and regroup at the third with Keiko being group with Harry and Diego. Keiko met with the town resistance leader, Wendell Mercer, who gave her a mission to check on a family he knows of that went silent when the Insurrectionists took over the town to which she complied and separated from Diego and Riley to check on the family using a warthog. She soon discovered that they were held hostage by an Insurrectionist commander on their farm with the Spartan slowly infiltrating the place to get the jump on them.
The Spartan soon found a portrait of the same baby she saved in Reach who is now adopted making her realizing that it's him while the family worked slow due to the lack of sleep. The commander grew impatient and tried to kill the boy using his magnum only for Keiko to lunge at him from the shadows killing him with her shotgun as a gunfight erupted between her and the terrorists. The boy's father gave Keiko a hammer to "give them hell" much to her confusion before an Insurrectionist grabbed her from behind with the medic smashing his face with the hammer given to her before having his face blown off with her shotgun. After the rest of the terrorists fled, Keiko went to tend to the minor injuries of the family as the boy had a bruise on his eye inflicted by a hit in the head by a magnum as the two bonded over their lost parents with him secretly realizing she was the same Spartan that saved him when he was a baby. When she was done helping the family, they offered her a meal to which she refused telling them to keep it before she left on a warthog.
Keiko soon witnessed Rosenda's fight against the Insurrectionist leader Henry Wells where he was killed by the Spartan leader then was extracted by a pelican as the HAVOK nuke was defused by Imogene.
=== Transfer to Oban ===
Keiko and the rest of Noble team except for Riley were soon transferred to Oban due to the planet being remote and territories where there is rumors of arms dealing and Insurrectionist activities. The new Noble-6 arrived in the form of Kyle Halsey who they all shared mixed opinions with.
== Personality and traits ==
Keiko back then was a bright and optimistic Spartan-III who tried to see the good in others while cracking jokes in the process. But the Fall of Reach had a profound effect on her resulting in her becoming anti-social and distanced herself from others becoming jaded by her own mistakes in succumbing to her own fears, she is the less vocal of the team and would pretend to listen to Harry's rants giving her an almost drone-like persona. She also has signs of post-traumatic stress disorder yet is shown to be a very competent soldier on the field having expertise with a shotgun.
== Trivia ==
* Keiko's favorite band is an old one called First Aid Kit with their song I've Found A Way being her favorite. She often hums it off duty.
