Francis Scott Key Fitzgerald vs. Nathaniel Hawthorne

Francis Scott Key Fitzgerald vs. Nathaniel Hawthorne is a battle fought between the Renewed Guild leader Francis Scott Key Fitzgerald and assassin Nathaniel Hawthorne acting on orders of Fyodor Dostoevsky.

It happened in Manhasset Security sometime during the Decay_of_the Angel' terrorist plot, coinciding with the hunt for the Armed Detective Agency after being framed as terrorists. At this time, Agency members Atsushi Nakajima and Kyōka Izumi plan to use Fitzgerald's Eyes of God to find Mushitaro Oguri in hopes of proving the Agency's innocence.

Prologue
Atsushi and Kyōka arrive at Manhasset Security, where they find an injured Louisa May Alcott who directs them to Fitzgerald. As Kyōka helps her out, Atsushi heads to Fitzgerald's office and finds him battling Hawthorne.

Battle

 *  Note: The details from the beginning of this battle are not shown. 

An injured Fitzgerald remarks how Hawthorne's religious views have considerably changed, but Hawthorne—seemingly brainwashed—asserts that he must invoke death to him for the sake of his beloved. Fitzgerald recognizes the latter to be Margaret and asserts that he does not care about Hawthorne's endeavors. Nonetheless, Fitzgerald becomes enraged at Hawthorne for forgetting his face, afterwards spending $50,000 for his ability.

Fitzgerald hurls a fountain pen that penetrates through Hawthorne's palm and gets lodged on the wall upon impact. Hawthorne then breaks through the windows and flees. Having witnessed the incident, Atsushi muses on the strength of the former Guild leader. Eventually, Atsushi converses with Fitzgerald and tries to convince him of the Agency's innocence, though Fitzgerald remains adamant in helping them, admitting that Fyodor now has an opportunity to freely perform his schemes in Meursault.

As Fitzgerald approaches his fountain pen on the wall, Hawthorne's blood bullet seeps out from the pen; Atsushi surmises that Hawthorne must have infused it with his own blood after it cut through his palm earlier. Fitzgerald admits premature defeat, as his Physical Enhance would not possibly make it in time to retaliate. The room's sprinklers are suddenly activated; Kyōka arrives and explains that she did so after seeing a notice from the display screens to "trigger the sprinklers". As a result, Hawthorne's blood gets diluted in the water, preventing Fitzgerald's death.

Aftermath
Atsushi and Kyōka manage to forge a deal with Fitzgerald, thereby allowing them to locate Mushitaro through Fitzgerald's Eyes of God. Meanwhile, Hawthorne's fate directly after the battle remains unknown.
