Atsushi Nakajima and Kyōka Izumi vs. Francis Scott Key Fitzgerald

Atsushi Nakajima and Kyōka Izumi vs. Francis Scott Key Fitzgerald is a skirmish fought between Armed Detective Agency member Atsushi Nakajima together with Kyōka Izumi against the Guild leader Francis Scott Key Fitzgerald during the three-way gifted organizational conflict.

It happened at a pier somewhere in Yokohama during Fitzgerald's attempt to personally capture Atsushi in pursuit of a particular Book.

Prologue
After the attack on S.S. Zelda and following the arrest of John Steinbeck and Howard Phillips Lovecraft, the Guild tactician Louisa May Alcott drafts a strategy proposal for Fitzgerald in cornering and abducting the their bounty target. Though the Guild members are implied to have objected Fitzgerald from collecting Atsushi by himself, Fitzgerald later sets out to personally meet Atsushi at a pier and to capture him once and for all.

Battle
As Fitzgerald remarks how boredom cannot be appeased by money or ability, Atsushi, who has been waiting for Osamu Dazai, reflexively lands a punch at Fitzgerald with his tiger limb, but he is blocked almost effortlessly by Fitzgerald. Though Atsushi realizes that Fitzgerald may be a combat-type ability user, he recalls inadvertently attacking Naomi Tanizaki and Kirako Haruno and resolves to defeat Fitzgerald to end the war.

Atsushi soon lands a kick towards Fitzgerald, but the latter is apparently unfazed and even notes his kick to be at least worth $10,000. He responds with a kick at Atsushi's abdomen that hurls him throughout the pier, afterwards clutching his head while reminding that they have put a bountiful price on him far more than what their target can seemingly offer. Regardless of his spite, Fitzgerald beckons Atsushi to come with him to provide his worth for another matter.

Before Atsushi can finish his thought of causing everyone trouble, the missing Kyōka suddenly turns up, whom Fitzgerald recognizes as part of the Mafia's lower ranks. However, she corrects him that she is a member of the Armed Detective Agency and instantly strikes towards Fitzgerald's direction with her tantō, which Fitzgerald evades. He remarks on their barbaric kind of welcome, while Kyōka quickly grabs Atsushi and jumps off the pier to land on a passing boat.

Aftermath
Seeing that they are getting away, Fitzgerald consults Louisa's strategy proposal on what to do next, but she has merely written in her instructions for him not to do anything regardless of the outcome of his encounter with the mantiger. Eventually, Louisa's strategy proves successful when Fitzgerald and Herman Melville manage to corner them, neutralize them as aided by Mark Twain, and finally abduct Atsushi aboard Moby Dick.
