Famous quote: "Hey Shido. Am I............really cute?"
Natsumi is the seventh Spirit to appear in the series. Natsumi has shapeshifting powers being able to turn anything into anything else within a range of 1 kilometer, including herself.
Natsumi's Angel, Haniel, besides being able to fly and transform objects or subjects, also has the unique ability of sending things into a different dimension through a mirror similar to Kurumi's shadow dimension. While in Natsumi’s personal dimension, the objects or subjects are put into a stasis field.
During her first meeting with Shidou Itsuka, Natsumi assumed the form of an adult woman, but she was later revealed to be a young girl, no older than Kotori Itsuka or Yoshino. Natsumi only assumed an adult form because she thought it was the only way people could notice her. Shidou is able to convince her to have more confidence in her natural appearance, and she lets him seal her powers.She later moves in with Shidou and the other Spirits and becomes friends with Yoshino. Although her power has been sealed by Shidou, she still has access to her adult form and occasionally uses it to tease Shidou and the other Spirits.
