Concealing Eyes - She can make things within her range unnoticeable, making it so even if concealed people speak others won't notice. Breaks upon physical contact with someone, though.
Otherwise, she's a normal teenager.
Kido grew up in the same orphanage as Seto and Kano. She is often listening to music through her earphones. Although she is naturally kind and has the most common sense within the group, she is short-tempered and has difficulty keeping other members, especially Kano and Seto, in line. She may appear scary at first glance, due to her dark expression and "glare-like gaze," as stated by Kano. Kido is also very motherly, as stated by Shintaro, who is also impressed by her ability to stay calm around her friends.
Due to her ability, her presence was weak and people often unintentionally ignored her, causing her to become scared of the possibility to disappear. Being unable to control her ability she would react shy and scared whenever someone would mention not noticing her.
After Ayano's death, Kido swore to become stronger so she could support everyone. Her determination makes her the leader of Mekakushi Dan. In order to make her "feel" more like a leader, Kano decided that they should start calling each other with their last names since it sounds like code names.
Would rather just wear her normal clothes.
