Kamika Todoroki serves as a Shikabane Hime under the Kōgon Sect, bound by contract to the monk Sougen Takamine. Her primary duty involves safeguarding the sect's main temple, restricting her field deployments against other Shikabane. Renowned among the oldest and most formidable Shikabane Himes, her power stems from the profound intensity of her lingering regret rather than combat experience alone, though this regret's origin remains undisclosed.

She earns the epithet "Sword Princess" through mastery of dual katanas, executing precise strikes capable of dispatching multiple Shikabane in a single motion. Her combat style prioritizes control and strategic efficiency, deliberately avoiding emotional impulses during engagements. Kamika maintains a cool, duty-driven demeanor marked by unwavering loyalty, fostering a reserved personality that often distances her from fellow Shikabane Himes.

Her surname Todoroki fuses meanings of "a loud noise sounds and crackles" with "flag," while her given name Kamika incorporates the characters for "god" and "good/beautiful." The Todoroki surname is shared with Shoto Todoroki from *My Hero Academia*, though no direct link exists between the characters.
