Katerina Campbell

Caterina is caring and protective toward Mana Walker and Nea D. Campbell. She provides the boys with a family environment despite the extraordinary circumstances surrounding their arrival.

The limited material depicting her emphasizes maternal warmth rather than involvement in combat or the institutions fighting over Innocence and Noah.

Her connection to the Campbell family also places her among the small number of ordinary humans who become entangled in the Noah's hidden history without belonging to the Noah Family themselves.

Caterina has no established Innocence, Noah abilities or supernatural combat powers.

Her significance comes from her knowledge and role within the Campbell household rather than physical abilities. The full extent of what she understood about the boys' origins has not been completely established.

Caterina belongs to the historical period surrounding Mana and Nea's childhood. She raises the two at the Campbell residence, creating the family relationship through which they receive the Campbell name.

Mana and Nea are the two infants produced when the previous Millennium Earl split into separate bodies. Caterina takes them in and becomes their adoptive mother, placing her at the beginning of the history that eventually produces the present Earl and the Fourteenth.

Fragments of this past become increasingly important as Allen Walker searches for the truth about Mana and the Fourteenth.

Mana Walker is Caterina's adopted son. His origin is tied directly to the division of the previous Millennium Earl.

Nea D. Campbell is Caterina's other adopted son and Mana's twin.

Cyrus Campbell is Caterina's younger brother and another member of the Campbell family.

Allen Walker is indirectly connected to Caterina through his relationship with Mana and his role as Nea's host.
