Lavi races against time to try to make it to Bookman's location to cure Lenalee's illness, and in the canyons he saves a young maid from an Akuma. The maid is actually Mimi, who plots to steal Lavi's Innocence and kill them both. Luck does not seem to be on her side as Lavi always manages to directly or indirectly stop her from stealing his weapon. Lenalee's condition worsens, and she tells Lavi to leave her but he refuses. The situation stirs up memories in Mimi of her own creation, and she becomes more determined to finish the mission and see Lulu Bell smile. She finally manages to steal Lavi's Innocence and attempts to kill the two Exorcists with her iron fans, but Bookman's arrival turns the odds back on the Exorcists' side. A defeated Mimi returns to Lulu Bell, who decides not to dismiss her. That is all it takes for Mimi to smile once more.
