Appearances:

An unknown child of middle-school age who appears to be a girl with light hair was shown hiding in Masumi Sera's room. The child's eyes have a remarkable resemblance to those of Shuichi Akai and Masumi Sera.

Appearance

The child appears to be a female of middle school age (12-15) with light colored, curly, neck length hair. The child has eyes similar to those of Masumi Sera and Shuichi Akai. In her appearance in 877, she was shown wearing a high-neck pleated top, hoodie jacket, and hat.

Plot overview

A child who appears to be a young girl first appeared on the call screen of Masumi's cellphone in Chapter 875. Later, when Ran, Sonoko, and Conan visit Masumi's apartment she is shown opening Masumi's door as Conan, Sera, Sonoko, and Ran rush to investigate a crime. It is implied the child was hiding in Masumi's bedroom while the other three were in the dining area because Masumi asks Conan not to enter her bedroom. The child later goes downstairs to the scene of the crime where she is seen by Conan.

Identity

The child's relationship to Masumi Sera is unknown. Sera testifies that she has two older brothers: Shuichi Akai and an unknown middle brother living in Japan. She says her father is dead, and her mother lives overseas America. Masumi says she doesn't doesn't have any more relatives close enough to depend on. She is currently being financially supported by a friend of her father's. If Masumi has told the truth, that leaves relatively few options for the child's identity assuming the child is related by blood somehow to Masumi.
