Grace Field House secret room (Anime)

The Grace Field House secret room is a room located in the houses on each of the five plantations at Grace Field House. The room is hidden from the orphans and located within the adjacent walls of the orphans' bedrooms and behind a bookshelf in the mother's office and serves as a room for the caretaker to contact and report in to headquarters using a large radio. The room is also used to hide the toys and belongings that former orphans took with them when they were shipped out.
