|“||Wanna join me at the kotatsu table and eat tangerines?||”|
Nire is a light-skinned, slender young woman with magenta eyes and chest-length auburn hair that is tied into a ponytail with a pink scrunchie to the left side of her head, with the rest of the hair loose. She has moderately prominent canines. When off duty, comfort appears to be the main factor in her clothing style. She has been seen lazing around her squad's strategy room in a light pink t-shirt under a black track jacket with pink outlines and two thin stripes on the sides of the sleeves, alongside a matching pair of pants. To hang out at Kageura's restaurant she donned a stylish track sweater and light-colored shorts.
Nire comes across as a very carefree person, bordering on lazy. She spends much of her time at Border under her kotatsu, and, if someone other than her teammates is brought to the strategy room, she will invite them to join her. She is very energetic and cheerful in other social situations, in sharp contrast to her demeanor during rank wars. Like Kitazoe, she is more concerned about the squad's ranking than Kageura or Ema, which may cause her to clash, albeit very light-heartedly, with her teammates; neglecting their safety for the sake of scoring more points. Even so, she is one to complain about her workload when carrying out standard Operator duties, claiming that her teammates would be lost without her. Her younger brother being very independent has led Nire to look for others to fawn over, so she may on occasion behave like an impish older sister with Ema in particular, expressing shock when he invited Chika Amatori and Izuho Natsume over to their strategy room and subsequently spying on them.
- (On various occasions) "Geez, you guys can't do anything without me."
- (To Hiro Kitazoe) "Hold him back and then you can die!"
- (To Masato Kageura) "Make sure you score points, Kage! Don't waste Zoe's death!"
- "They're... girls! Yuzuru brought girls over!"
- (To Chika Amatori and Izuho Natsume) "Wanna join me at the kotatsu table and eat tangerines?"
- "I can't tell what they're saying... But it's good to be young, Yuzuru...!"
- (To Kageura's friends) "Heeeey, you sad, lonely boys! I, Hikari, am here for you!"
- (To her teammates) "Ooh, and he's an hottie to boot!"
- "Hikari" (光?) literally means "light", while "Nire" (an alternative reading of 仁礼 Nirei?) means "kindness, courtesy".
- She likes manga, animals, shopping, and idling about.
- She does not let her teammates enter her kotatsu without her explicit permission.
- Her grades are among the worst out of all the 17-year-old agents.
- The image on the back cover of Volume 14 reveals that not only she was barefoot when Ema took Chika and Natsume to the strategy room, but also that she had put on her pants in reverse, her back pocket being visible on the front.
- The author called her a "sleepy helpful sister".
- Her voice actress, Yurie Kobori, also voices Futatsugi and Mira.
