   Summary

   After the events in 6.3, Lumine has chosen to accept Dottore's offer and has been working under him for quite some while now. However, it has come to Dottore's attention that the girl was hiding a part of herself. Having recognized her age regression, Dottore decides to further experiment on the situation, turning her life upside down and exposing all her quirks to himself.
