Inca Kasugatani

is a Fourth Generation, as stated by her due to her ability not fitting into either the 2nd or the 3rd generations ability's description, and is famously reputed as a fire thief across the country for her acts of saving people from fires in exchange for their valuables. After the events of her becoming the Fifth Pillar and awakening her pyrokinetic ability, she willingly decides to join the White-Clad.

Appearance
Inca wears a school uniform with a knee-length skirt. While working, she uses a checkerboard patterned scarf to hide her face and also wears a dark hoodie. Her hood has eye-like marking upon its sides.

Personality
Inca values life above all else, claiming that nothing is more important than living. The distinction that becomes clear over time is that she values living her own life how she sees fit as most important, and if people get in her way of doing so, she will not hesitate to betray or hurt them. This is evident in how she justifies stealing from those she helps by saying that their lives are more important than their belongings. This belief was born from her desire to escape from a disaster in the past. However, the disaster also created Inca's obsession with danger and an apparent invincibility complex. She is quite selfish and will chase after her own desires more than anything, being highly indifferent about what they cost. Claiming to only feel alive when in danger and cheating death, Inca is an adrenaline junkie that despises the idea of a world without the sensation of danger or death defying circumstances. She will recklessly place herself into possibly fatal disasters to feel a rush of excitement and loves when chaos emerges out of peace, embracing rather than fearing it. Inca is a person who would rather live a life where she can take any risk she wants regardless of consequence, rather than abide by rules that others tell her to follow.

Her love of danger and abilities created a sense of destiny and fate that she strongly believes in. This deterministic reality formed due to the presence of her powers, particularly when they chose to appear and work to their fullest, resulting in a large inflation of her ego. This strong belief and ego growth has also appeared to absolve her of any sense of responsibility for her choices or actions which only furthers her danger seeking obsession.

Inca's fixations on danger and her own apparent invincibility around fire, lead her to believe her own life is more important than anything else, including the lives of others. She desperately values her own freedom more than anything else and hates people trying to make choices for her, and will kill people should they try to stop her from exercising it, including her former friends. While initially shown to be willing to act to protect her friends, she likely saw them as little other than tools that could help her get what she wanted and would discard them if they didn't do what she liked. This is further expressed when she quickly got over seeing a supposed friend killed, despite being initially terrified, and willingly agreed to go with the people who committed the act. Inca actually cares very little for anyone except herself, and the next rush of danger she can feel. While she makes choices that have not resulted in her harming many people personally, even saving some of her comrades, she is extremely selfish and materialistic in her thinking, and cares very little for the consequences of her actions as long as she gets what she wants.

While she initially resists attempts to recruit her into the White-Clad and attempts by Company 8 to take her into protective custody, she concludes that her being protected would lead to a normal life, which scares her even more. She considers a normal life a prison of predictability, with no way to feel the excitement she obsesses over. She views playing a game where she knows she could lose her life at any moment as giving her a rush that cannot be matched, and a life so exciting, nothing can top it. It is in this pursuit of selfish fulfilment, she willingly allies herself with the Evangelist in order to feel an even greater sense of danger that the other side cannot offer her, while being excited by the idea of Shinra chasing after her as an enemy rather than trying to help her.

Abilities
During the Great Fire, Inca acquired the ability to detect the pathway that heat will take via her sense of smell, leading to categorising herself as a Fourth Generation. Two years later, Inca awakened the rare Ignition Ability Adolla Burst, which allows her to manipulate the pathway of heat to create explosions.

Background

Though she lost a lot during the incident, she used her new-found power with Panda and Sancho to rescue people immediately from fires in exchange for their valuables, leading to her becoming famous across the country for being a fire thief.
