Kat

Kat is the daughter of Naoki Himura.

Overview
In 2016, Kat and her mother moved to a new house. As her mother attempted to re-decorate the walls, she accidentally scratched a Celtic Monster Trapping Sigil, causing a Soul Eater to break free from its bounds.

Kat began hearing footsteps, and noticed her room temperature drop noticeably. Naoki brushed it off as a nightmare. Although unhappy with their new home, Kat listened, and asked for a glass of water.

Suddenly, after her mother left, the lights went off and the door slammed shut on their own. Terrified, Kat hit under the bed, and saw a shadow of feet. She is then grabbed from behind and dragged off, Kat screamed.

The incident left Kat in a coma. Sam and Dean Winchester, posed as FBI agents, came to investigate. As part of a plan to destroy the Soul Eater, Dean allowed himself to get taken to the Soul Eater's nest, where he encountered Kat. Dean promised her a way out, and after both he and Sam finished drawing the spell, Kat found her mother (who had also been taken) and returned to her body.
