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. Iris is also a very kind-hearted person, as she wishes to help and give support to everyone in need, despite the circumstances.

Introduction arc
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 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 seen happy to watch Shinra with an delighted smile.

The next day, while on the roof, Maki displays her abilities to Iris by creating Pusupusu, but their conversation gets cut short when a fight between Arthur and Shinra breaks out in front of them. 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 fight from the sidelines. Later, she, alongside the rest of the 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 Flame Human, 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 room, where they spot Mikako's father, casually sitting by the table. When Arthur impales the man with his weapon, the building's roof starts to collapse, but the team manages to escape. While outside, Iris sees a saddened and scared Mikako on the sidewalk and thinks to herself on what she could do to help, but realizes that her only available solution in a situation like this is to pray.
