Roja Hachimaki

Roja is established primarily through her work as a Keeper, with relatively little attention given to her personal life.

She participates in dangerous Choujin operations despite serving outside Yamato Mori's central organization, reflecting the broader network of regional Mori agencies responsible for handling supernatural threats.

Tokio jokingly addresses her as "Her Majesty," providing one of the few personal touches associated with their interactions.

Roja can make her own body thorny, covering herself in durable spikes that punish opponents attempting to make direct physical contact.

She can also transfer the same property to objects she touches. This allows equipment, surfaces, and potentially improvised weapons to become covered in strong thorns.

Roja possesses Raise like other Choujin and can recover from otherwise fatal injuries under appropriate conditions.

Roja appears among Keepers from outside Yamato Mori as the scope of the conflict surrounding the Tower of Mourning grows.

Her presence establishes Nagamata Mori as another regional Keeper organization rather than treating Yamato Mori as the only institution responsible for managing Choujin.

Roja becomes involved in the larger fighting surrounding Sora and the Tower. Her participation places regional Keepers directly in a conflict that increasingly affects multiple prefectures rather than Yamato alone.

Tokio Kurohara encounters Roja through the broader network of Keepers and jokingly calls her "Her Majesty."

Sora Siruha becomes the central figure behind the conflict into which Roja and other regional Keepers are drawn.
