Hikari Nire/Plot

Background
Nire joined Border approximately two years before Chika Amatori and Yūma Kuga. At some point Nire joined Kageura Unit and scouted Yuzuru Ema, which she used as leverage to install a kotatsu in the strategy room. The unit climbed all the way to A-rank no. 6 before being demoted when Masato Kageura threw an uppercut at Eizō Netsuki.

Introduction Arc
Kageura Unit presumably takes part in the extermination of all Rads in Mikado City.

Large-Scale Invasion Arc
Due to Masafumi Shinoda preventing B-rank units with missing members from fighting against Aftokrator's forces out of fear of capture, Kageura Unit is not deployed.

Round Two
Since Azuma Unit, Katori Unit, Ōji Unit and Yuba Unit competes in a four-way rank battle in the day division on February 5, and Ikoma Unit and Ninomiya Unit are known to have clashed on that day, Kageura Unit presumably faces off against them in the night division.

Round Four
On February 15, during the night division of rank battles, Kageura Unit faces off against Ninomiya Unit, Azuma Unit and Tamakoma Second. As soon as the match starts, Hiro Kitazoe asks for Nire's help to find a good spot to launch his Random Meteor from. However, he fails to score any points, prompting Nire to chide him. He asks her to send a list of the locations Azuma Unit might be hiding in, but as she complains the Gunner is attacked by Masataka Ninomiya, who begins chasing him. She tells her teammate to hold him off as long as he can so that Kageura will be able to score more easily, but he incurs her ire when he insists that he will fight Yūma Kuga first. She cheers when the ace of their team takes out Sumiharu Inukai. When only Haruaki Azuma, Kageura and Ninomiya are left, Kitazoe and Nire pressure their captain into staying hidden until the end. Time runs out without further developments and Kageura Unit ties in second place with Azuma Unit.

Galopoula's Blitz
The following day, Nire is lazing around the strategy room when Ema brings Chika Amatori and Izuho Natsume over. She is surprised that her teammate would hang out with girls, but she quickly switches to offering them a sit around her kotatsu and playing with Natsume's cat. She stops to help Ema set Chika's Lightning to fire shots rigged with Lead Bullet, and then watches his interactions with them despite the absence of sound, inferring that they are having a good time.

Round Five (Night)
On February 19, the night of Galopoula's blitz, Kageura Unit fights a rank battle against Azuma Unit and Yuba Unit.

Round Six
Kageura Unit fights against Ninomiya Unit, Azuma Unit and Suzunari First in the night division of the sixth round of rank battles. Kageura Unit and Ninomiya Unit tie at the top with three points. No unit receives the survival bonus due to there being multiple survivors. Following the match, Kageura Unit remains in second place with a point total of 34.

Round Seven
A few days before round seven, Kageura invites his teammates and his other closest friends to his family's restaurant. Nire arrives after Ema has left. Kageura tells her that she is too late for dinner, but she asks him to cook more okonomiyaki as she cheerfully greets everyone. Over the next few days, she researches their upcoming opponents together with Ema. When March 1 comes and they discover that Tamakoma Second has added a new member, she takes not of his good looks. As Kageura and Kitazoe discuss how they will high tin Cityscape D, Nire asks Ema if he will snipe through the walls, but he impresses her with his resolve by saying that he will enter the mall and fight at Gunner range.

The match begins and Kageura and Kitazoe team up against Tatsuya Kuruma and Kō Murakami. As they fight inside a shop, however, Taichi Betsuyaku switches off the lights. Nire scrambles to activate visual support, but moments after she does, the Sniper turns them on again. Dazzled, Kageura suffers a serious hit. While continuing to complain about her teammates' overreliance on her, she sends Ema the coordinates of the fusebox. She is visibly displeased with Sumiharu Inukai's comments about Kageura's lacking performance at the end of the match.

Round Eight
On March 5, Kageura Unit faces off against Ōji Unit and Azuma Unit in the day division of rank battles. Azuma Unit wins the battle, which took place in Exhibition Hall, with a final score of 4-3-3.
