Mari Kusakabe

is a citizen of Tokyo, that transformed into a Demon Infernal.

Appearance
Before becoming an Infernal, Mari had shoulder length black hair, sharp teeth and soft eyes.

Personality
Mari was a very caring for towards her two sons. Encouraging Shinra’s dreams of being a hero and always being attentive towards the newborn Shō. However, she would lightly scold Shinra if the need the need arose, telling him to sit further away from the television and would remind him that misbehaving children are sent away to The Nether when he didn't do his chores.

Background
While a teenager, Mari unexplainably feel pregnant, leading to many doubting her claim that it was a virgin pregnancy including her mother. She gave birth to Shinra in Year 178, and in Year 183 gave another virgin birth to son Shō. The Holy Sol Temple successfully put pressure on Shinjuku Community Center to not report the story.

In the following year, after witnessing Shō surrounded by the Adolla Burst flames, she turned into a Demon Infernal with two curly white horns, a skeletal spine that also connected to her long spiky tail. Afterwards, she died, despite both her sons surviving the act that was evidently caused by Haumea. Shinra was saved from the Inferno by Leonard Burns and after making use of his Third Generation abilities in the moment of chaos, jolted towards the wall and knocked himself out, leading him to forget the majority of the events. Shō (presumed to be dead) was taken by the Evangelist. Witnessing her death traumatized Shinra, leaving him with his nervous grin but a burning desire to save people and uncover who killed her. While Shō claims to have no memory of his mother, having been raised by The Preacher and viewing it as his only parent.

Post-Stone Pillars Arc
At the time Shō was investigating his family records, Mari has an Adolla Link with him.
