Nathaniel Hawthorne/Synopsis

The Guild Arc
During the onset of the three companies conflict, Hawthorne arrives as "the package" from the Guild along with his fellow members Margaret Mitchell, Herman Melville, and Mark Twain. After defeating the Armed Detective Agency and the Port Mafia, Hawthorne asks where Edgar Allan Poe and Louisa May Alcott are. Margaret answers that they stayed behind due to their shared fear of heights. Hawthorne and the other Guild members walk off, leaving Twain behind.

Later, Hawthorne and Mitchell are tasked to guard the S.S. Zelda during their replenishment. He is seen sitting on a chair and reading his Bible. He notices Mitchell staring at him and tells her to stop bothering him, as she is disrupting his conversation with God. Mitchell uses her ability to dismantle the pages in his Bible. Hawthorne stands, telling Mitchell that God has made it his mission to pass judgement onto sinners.

The two quarrel a bit, before a worker on the ship brings the pair a letter found among the cargo. They read the letter delivered by Port Mafia boss Ōgai Mori, threatening to obliterate their ship, Hawthorne's life, and Margaret's life. Hawthorne soon demands that the crew complete the two-hour task in thirty minutes. When Margaret downplays the letter as nothing but harassment, Hawthorne scolds her, reminding her that the ship was the Guild's only base on the frontline.

They are interrupted when a crew member informs them that they have found a suspicious man on board the ship. Dismissing Motojirō as an unworthy opponent from the mafia, Hawthorne activates his ability, The Scarlet Letter, on Motojirō and tosses one of his lemon bombs at himself. However, they are shocked to find Motojirō unscathed from the blast, who soon has an entire crate of lemon bombs drop and detonate onto the Zelda, compelling the Guild members to abandon ship.

Not long after, Hawthorne and Margaret encounter the Guild's senior secretary James L. along their escape route. However, he is actually filled with lemon bombs, forcing Hawthorne to shield Margaret and himself from the explosion. As he and the other crew members anticipate their enemy, Ryunosuke Akutagawa arrives and impales Hawthorne and the others, resulting in a battle between the two. They realize the similarities between their abilities, both of which manipulate matter at various ranges for both offense and defense. Eventually, during Akutagawa's final blow on his opponent, Margaret embraces Hawthorne to prevent him from getting stabbed.

After the battle with Akutagawa, Hawthorne wakes up and is greeted by Francis Scott Key Fitzgerald, who explains that Margaret will probably not gain consciousness. Hawthorne laughs and calls her a foolish woman, recalling how she protected him at the last minute. Hawthorne wonders why she would do that if she wanted to restore her family's honour. Fitzgerald explains that she wanted to pay back a massive debt her family owned, though he thinks that her dream shall never happen now. Hawthorne suddenly gets up and blames Fitzgerald by saying that Fitzgerald is the one who took away Margaret's dream, upon which he vows to restore her honour for her and leaves.

Towards the end of the Guild war, Hawthorne is seen with Fyodor Dostoevsky and has joined the Rats in the House of the Dead on the condition that he provide Margaret the treatment she deserves.

Cannibalism Arc
One night, Armed Detective Agency director Yukichi Fukuzawa is attacked by a masked assassin, who wounds him in order to enable a virus activate in his body. The next day, mafia boss Mori and Elise are monitored by the same assassin, who sets off a bomb in their car. Though they evade it with Mori's ability, a disguised Fyodor stabs Mori to have a similar virus activate in him. Eventually, the assassin is unmasked by Akutagawa and revealed to be Hawthorne. However, it turns out that he has no memory of Akutagawa nor anyone else except Margaret and her comatose condition.

Hunting Dogs Arc
Following the events of Cannibalism, the murder association known as the Decay of the Angel makes their move and frames the Agency as terrorists. Hence, Atsushi Nakajima and Kyōka Izumi look for possible allies to help prove the Agency's innocence, including Fitzgerald. As they arrive at his office, they spot an injured Louisa; Atsushi also finds Fitzgerald battling Hawthorne. Fitzgerald attacks Hawthorne with his fountain pen, which penetrates the assassin's palm. The latter then crashes down the window and escapes.

Later, as Fitzgerald is about to remove the fountain pen from the wall, Hawthorne remotely activates his ability using the blood inside the pen from earlier. However, Kyōka activates the sprinkler system as indicated on the screens – a message sent from an outside party – in time to dilute Hawthorne's blood and prevent the attack on Fitzgerald.

Sky Casino Arc
Hawthorne later hovers outside the Sky Casino after Atsushi has saved the casino manager Sigma from falling off the floating establishment. Hawthorne shoots Sigma and, afterwards, Atsushi, though the latter manages to survive his wound in that moment. Before Hawthorne can launch a second attack on Atsushi, Lucy Maud Montgomery immediately transports him and herself to Anne's Room. However, Hawthorne is able to stealthily enter the dimension after connecting a thin thread of blood to Atsushi. As he wounds Lucy with his ability, Anne instantly captures him. He tries to attack the doll with his blood bullets, but he ultimately fails, given the rule that nothing can harm Anne inside the dimension. In the end, Hawthorne is dragged and imprisoned in Anne's secret room.
