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-colored headband, black veil, long light gloves and a brooch, which is shaped like the insignia of the Special Fire Brigades. 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 though she has no fighting capabilities.

Plot
Iris, alongside the rest of the 8th Special Fire Brigade, arrives to save the train station from a Flame Human, where she is ordered by Akitaru to begin the prayers. When the threat is defeated, a light pad starts falling from the ceiling, straight at the girl, but she is carried to safety by Shinra, whom she thanks afterwards. Later, at the 8th Special Fire Fighting Church, Iris takes a shower with Maki, after which the two head out to the meeting room, where Akitaru delivers a talk regarding known information of 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. After Shinra defeats the Flame Human, Iris was happy to see Shinra with an happy smile. The next day, while on the roof, Maki displays her powers to Iris by creating a sentient fireball, but their conversation gets cut short when a fight between Arthur and Shinra breaks out. She overlooks the fight between Maki and the two Second Class Fire Officers.

Later, she, alongside the rest of the Blue Lines, 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 Flame Human, a burst of flames emerges from the apartment's balcony, much to their surprise.
