So sad they have to say goodbye here. I read that this was because the magazine the manga was in closed down, so the author had to end the series temporarily.Wish he had made a chapter where Bon visits Ream in her timeline.
This chapter makes reference to the
Moberly–Jourdain incident, when two tourist claimed to have time slipped into 18th century and seen Marie Antoinette. The man Bon and Ream rescue is a real person.
Ambrose Bierce was a famous American writer and journalist who disappeared during the Mexican Revolution.
