For all her bad manners and constant state of drunkenness, she has a certain charm that is hard to put your finger on. Much like a stray cat claiming her territory, Barbara settles herself into Mikura’s apartment. This propels the creatively congested Mikura to write again. His life takes a drastic turn for the better. Is Barbara a muse? An artist’s saviour? Or is she a spell-casting sorcerer?
