The Role of Sister Iris in Company 8




Arc | Vs. Special Fire Force Company 5 |
---|---|
Chapters | 13 – 20 |
Episodes | 5 – 7 |
Sister Iris is an integral member of the Special Fire Force Company 8, initially hailing from the Holy Sol Temple. Her role encompasses performing rituals and prayers for Infernals, guiding their spirits peacefully as they are dispatched. Iris’s commitment to her faith is rooted in her traumatic past at the St. Raffles Convent, where she, alongside Hibana, faced the devastating loss of their peers in a tragic fire.
After this harrowing event, Sister Iris continued her dedication to the Holy Sol Temple, contrasting with Hibana, who distanced herself from the church. As a member of Company 8, Sister Iris’s presence is essential during missions, particularly given the belief that Infernals can transition to the afterlife more peacefully when blessed by a nun or priest.
Exploring Sister Iris’s Identity
Sister Iris: The Doppelganger of Amaterasu




While much about Sister Iris’s past seemed uncovered during Hibana’s story arc, deeper mysteries surrounding her identity emerged in the Vs. Special Fire Force Company 4 arc. Notably, Shinra experiences a vision of a woman strikingly similar to Sister Iris, whose malevolent nature creates intrigue about her true identity. This woman was later identified as Amaterasu, the survivor of the Great Cataclysm.
Amaterasu possesses both the Ignition ability and the Adolla Burst, later becoming confined in a container that powered Tokyo for generations. Despite her pleas for freedom, she remained trapped, highlighting her tragic existence and complex connection to Sister Iris.
Understanding Amaterasu’s Importance
Amaterasu’s powers, linked to the Adolla Burst, make her a significant figure in the narrative. As the First Pillar, she encapsulates humanity’s darker emotions and chaos. For 250 years, Amaterasu harbored resentment towards humanity, leading to her descent into madness. In a striking twist, Sister Iris is unveiled as her Doppelganger, a parallel representation of Amaterasu’s nature.
Within the Return to St. Raffles arc (Chapter 200), Hibana discovers Iris’s status as the Eighth Pillar, a revelation that shakes her understanding of their shared experiences. This moment emphasizes the complexity of their identities:
- A Doppelganger serves as an alternate version of a person existing in Adolla, also known as Hell.
- The essence of a Doppelganger is shaped by external perceptions, creating a reflection of others’ beliefs.
- Amaterasu embodies kindness, mirrored by Sister Iris’s compassionate persona.
The circumstances surrounding Sister Iris’s origins call into question her creation as a Doppelganger. It becomes apparent that Sister Sumire, a nun from the convent, had been conducting experiments to create Doppelgangers for centuries, ultimately leading to Sister Iris’s existence. Tragically, the fire that claimed the lives of the orphaned children was the result of these experiments, forever linking Iris and Hibana to their grim upbringing.
As Sister Iris begins to harness the powers of the Eighth Pillar, she reflects on her significance within the narrative. Her awakening ignites hope as she embraces the potential for a new destiny. With her devotion and the strength of her prayers, Sister Iris understands she must navigate her path amidst the chaos.
