Kagami

Kagami (鏡, Kagami) is a tsukumogami living in Nagatsuki house and serving Botan Nagatsuki.

Plot
Kagami was with Nagi in the town, but then remembered that Hyoma would be coming to their house and they quickly rushed back. Upon arriving, Hyoma was already there and Kagami apologized for being late. As they spoke and Hyoma mentioned that they may be taking advantage of Botan, Kagami and the rest got angry and Nagi attacked Hyoma and started a fight. Upon learning that Botan was coming earlier home, Kagami asked them to stop fighting, but Nagi yelled at her to shup up and Kagami got scared and apologized. As Haori ordered everyone to stop them fighting, they all jumped and attacked Hyoma knocking him on the ground and thinking someone else was going to stop Nagi.
