Chapter 4:
In the past, Koto lived with Inari, who worked for the Chief Priest of the shrine and was also her teacher.
Chapter 5:
She realized that Inari may be her real dad, and that the black rabbit in the picture may really be her mother, but kept it a secret.
Chapter 6:
In the present Looking Glass City, the Council of Three thinks that Koto's red eyes may be a sign of their mother's return.
I'm sure that's what your 
mom would say, Koto.
Ich bin mir sicher, dass deine Mutter
 das auch gesagt hätte, Koto.
Seguro que eso diría tu madre, Koto.
Eso es lo que diría tu madre, Koto.
Je suis sûr que c’est
ce que ta mère voudrait aussi,
Aposto que sua mãe diria o mesmo, Koto.
