Iris

is a sister, and a member of the 8th Special Fire Brigade of Tokyo.

Appearance
Iris is a young girl of average height with blonde hair and green eyes. She is seen wearing her own version of the brigade's bunker gear, which consists of a scapular underneath her light top and dark dress, a blue-coloured headband, a black veil, long light gloves and a brooch, which has a cross-like symbol on it. Those are later topped by a protective jacket and a mouth gas mask.

Personality
Iris is shown to have a sisterly relationship with Maki, and, like her, is very courteous to others. She is also shown to be rather shy around strangers, but is brave on the battlefield, as evident with her standing face-to-face with a threat as dangerous as a Flame Human without being fazed, even without having any sort of abilities. Iris is also a very kind-hearted person, as she wishes to help and give support to everyone in need, despite the circumstances at hand.

Introduction arc
Iris, alongside the rest of the 8th Special Fire Brigade, arrives to save a train station from the Flame Human, where she is ordered by Akitaru to begin the prayers. When the threat is defeated, a light starts falling from the ceiling, but the girl is carried to safety by Shinra, whom she thanks afterwards. Later, at the headquarters, Iris takes a shower with Maki, after which the two head out to the meeting room, where Akitaru delivers a speech about the Human Body Ignition Phenomenon. Later that night, Iris, alongside the rest of the brigade, moves out to save a factory from a Flame Human. When the brigade arrives, Iris joins the others in fighting the threat and, after Shinra defeats her, she is seen enjoying watching the boy with a delighted smile.

While on the roof, Maki shows her ability to Iris by creating Pusupusu, but the conversation between the two gets cut short when a fight between Arthur and Shinra breaks out. When the two boys start bickering, Iris reassures Shinra that he has as much cachet as Arthur does. When Takehisa arrives and orders Maki to fight the two Fire Officers, Iris overlooks the entire event from the sidelines. Later, she, alongside the rest of her team-mates, attends an incident in the Iriya District and notices the victim crying, but Akitaru assures her to leave the girl be. Before the brigade could confront the threat, Iris gets distracted by a burst of flames, coming from the apartment, and thinks it to be Maki's doing. The whole brigade then storms into the building, where they spot Mikako's father. When Arthur impales the man with his weapon, the building's roof begins to collapse, but the team manages to escape. While outside, Iris spots a saddened and scared Mikako on the sidewalk and wonders about what she could do to help, but realises that her only available solution in a situation like this is to pray. Iris is later present during the Fire Officer Newcomer Tournament, observing the event alongside her team-mates.
