Kira

Personality Kira has an upbeat and outgoing personality. As is typical of members of the Middle, she enjoys combat and carnage and carries herself without much seriousness. Kira holds a lot of admiration for those she considers "badass", such as her father Matthias, lending to a love of Fixers and television. Having grown up getting whatever she wanted from her father in the confines of the House of Spiders, Kira appears highly naive and somewhat lonely.

Kira comes off as overly amicable and sincere, to the point of chatting up the members of the LCB and LCD during the House of Spiders' attack to the company's headquarters; she approaches the other four Nursefather apprentices in the same manner, having tried and failed to involve them in her hobbies. Given how much her hobbies have defined her personality and upbringing, Kira is also prone to viewing the real world through the lens of a story, dismissing insults and provocations as parts of a character someone is playing.

Story Prior to Limbus Company Growing up, Kira's relationship with her "papa" was built on a shared love of entertainment and little else. Matthias indulged her greatly, letting her spend as much time eating junk food and lazing off as she wanted, treating her more like a buddy than his daughter. Kira has spent her time lonely, disconnected from the actual members of the Middle, and clinging to her hobbies as a means of coping with the alienation and bonding with her father.

Canto IX: The Unsevering After Hong Lu, Ishmael, Outis, Rodya, and the three members of the LCD had reached the observation room of the Limbus Company HQ and restored the camera feed, the group observed as Matthias, the Nursefather of the Middle, rampaged through the LCA team that had been sent to secure the area. Kira quietly snuck into the room during this time, and nonchalantly joined their conversation as the group marveled at Matthias' incredible strength. When the others were taken aback by her presence and wondered if she should be considered a threat, Kira told them to relax and keep doing their job, idly chatting with them until Matthias noticed her absence and the Limbus Company employees were forced to square up against them.

Moses was able to hold the two back temporarily by making use of a Distortion called the Human Thunderbolt, which possessed the corpse of a nearby LCA agent and turned against the duo, allowing the group to make their escape. While Matthias stayed back to deal with it, Kira gave chase. To distract Kira, Moses released the Abnormality Drenched Gossypium, hypothesizing that Kira's tendency to rush into difficult "boss battles" by herself would result in her remaining stuck in place for long enough for the group to escape. Kira was heavily injured after acting just as Moses had predicted, but was saved after Matthias joined up with her again, defeating the Abnormality with just one swing of his sword.

Matthias engaged in a hunt with the LCB and LCD, defeating a number of Peccatula and the Ambling Pearl Abnormality along the way as they tried desperately to outmaneuver him. He was eventually stopped by Vespa's arrival and the news that the Dihui Star had retrieved the Golden Boughs, which led him to leave with the wounded Kira.

Afterwards, Kira and Matthias would spend time watching television and eating snacks in the Corridor of the Middle portion of the House of Spiders. During Limbus Company's retaliative raid on the Nursefathers, the father and daughter were confronted there by Don Quixote, Hong Lu and Yi Sang, alongside Ezra, Moses, and Vespa. At the time, it was made known that Matthias has been a shallow father to both her and Ryōshū. Following a brief verbal standoff, the two groups engaged in battle. Eventually, while Matthias evaded a deadly attack from Moses, Kira managed to catch Vespa off-guard with a sneak attack, hoping for a follow-up attack from her papa; however, Matthias brutally cleaved her in half to land a clean hit on the Yellow Harpoon, claiming that "a little sacrifice ain't a thing if it's for one of us". Aeng-du radioed the team to tell them that the LCC Department was requesting that Kira be captured alive, and so Hong Lu used one of the group's K Corp. ampules to save her life. Afterwards, Matthias was killed once and for all, and Kira was presumably taken to the LCC Department following the successful raid on the House of Spiders.
