A promising shinobi from a peculiar bloodline known as the Kishimojin Family: Ichika Kishimojin. Having a heart of justice and a burning aggression towards mononoke, Ichika is a perfect member for the Bureau. Though she can act as a spy for the Bureau, she is more than capable of combating against a mononoke. Initially, Ichika may come off as cold and harsh to others, especially mononoke, though she will warm up to others overtime. When she first meets Jirou Azuma, she doesn't like him for his fused mononoke state with Ragou. Later, the three form a friendly bond.

Spoiler

When Ichika was young, her mother was turned into stone by a mononoke. Upon learning this, she vowed to find the mononoke that caused the death of her mother and to avenge her. Despite this, whether her mother is alive or not is unknown, and is possible that she can be brought back to life if the stone can be undone. Due to this, Ichika hopes she can save her mother as well.

Spoiler

Due to her being a Kishimojin, Ichika has an ability known as "flameblood" that only females in the bloodline have. Her parents originally didn't want her to be a shinobi because of this, though it backfired upon the loss of Ichika's mother. After the Amagi debacle, Ichika learned about her ability and began to train in order to use it. When using flameblood, users experience bursts of inhuman speed and power. On top of that, when it bleeds out, it can be ignited and will only go out when the user wills it. Though the ability is a great advantage, it is very taxing on the user.
