Iris

is a sister from The Holy Sol Temple, 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. For most of the time, she wears a habit that has the Special Fire Brigade crest on it. She is seen wearing her own version of the brigade's bunker gear while in scenes of fire, 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. 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. She is caring and as a Sister, believes in religious faith. Though incompetent, she shows bravery 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.

Background
Iris attended The Holy Sol Temple during her youth, with Princess Hibana as her colleague. Since she addresses Princess Hibana as, it is implied that the two have shared a close relationship.

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. The next day, Iris moves out with her brigade to dispose of Setsuo Miyamoto, an ex-convict who turned into a Flame Human in the courthouse.

VS 5th Special Fire Brigade arc
When their Brigade catches up to Shinra, who went ahead after Setsuo fled from the scene, Iris and the rest find themselves in a confrontation against the 5th Special Fire Brigade. After a little scuffle between members of both brigades, the 8th look intimidatingly toward the 5th as tension is caused between them, though Iris looks slightly worried. As she observes the 5th, she notices and looks at Hibana standing upon them. Hibana looks back at her, and soon turns back to go back to their base. The next day, at the church, Iris is called out to be the only 'regular' person within the 8th by Shinra, as everybody else is weird in some way. Later on, Iris goes to the courtyard to perform a purifying ritual, in which she thinks back to her past at The Holy Sol Templ, and is revealed to know Hibana as they used to go to there together. While only donning a wet towel, Shinra unintentionally walks in on her, to which he grows an infatuated grin on his face. Iris tears up at the thought of Hibana. As she notices Shinra and puts a towel on, he notices she was crying and asks if she's okay. Putting on a fake smile, she tells Shinra she's fine and not to worry, and walks away. Later on, Iris is seen visiting the 5th Special Fire Fighting Industrial Complex to talk to Princess Hibana directly. When confronted, Iris questions Hibana on her actions of experimenting on Flame Humans illegally and wants to know what she truly desires, though Hibana reacts viciously, tearing off Iris' habit, leaving Iris in just her panties and bra. Hibana grips Iris' face and tells her that her existence within the Special Fire Brigade is trivial. She also says that only demons exist in this type of world, making Iris think about Shinra.
