Sickle is a female homunculus created by Huey Laforet and a member of the Lamia. In December 1934, Sickle and other members of the Lamia are sent to Chicago to intervene in the Russo Family's sudden meddling with Lamia affairs and investigate Nebula's current status. Two months later in February 1935, Sickle and the Lamia reconvene in New York to act as Huey's bodyguards during the events of Ra's Lance. Sickle has a scornful attitude and often speaks in a blunt, masculine manner. Her violent temper culminates in physical violence against the Poet whenever he tests her patience beyond toleration in non-combat situations. It is implied that, as with the other Lamia members' eccentricities, Sickle's 'odd demeanor' is a defense mechanism she has deliberately created to distance humans from her.

Baccano!
During the early 1930s in Chicago, the transcontinental train, Flying Pussyfoot, is starting its legendary journey that will leave a trail of blood all over the country. At the same time in New York, the ambitious scientist Szilard and his unwilling aide Ennis are looking for missing bottles of the immortality elixir. In addition, a war between the mafia groups is getting worse. On board the Advena Avis, in 1711, alchemists are about to learn the price of immortality. Based on the award-winning light novels of the same name, Baccano! follows several events that initially seem unrelated, both in time and place, but are part of a much bigger story—one of alchemy, survival and immortality. Merging these events together are the kindhearted would-be thieves, Isaac and Miria, connecting various people, all of them with their own hidden ambitions and agendas, and creating lifelong bonds and consequences for everyone involved.
