Flagon Turret (No Regrets)

Flagon was a member of the Survey Corps and squad leader (分隊長) at the time Levi Ackerman, Farlan Church and Isabel Magnolia joined the military. He disliked the idea of allowing the trio of former thugs join the Survey Corps, especially since they were asigned to his squad.

Appearance
He was a slim young man with blonde, short, and partially disheveled hair, and a small beard. He was frequently seen showing an expression of disgust due to his dislike towards Levi, Farlan and Isabel and their actions in the Survey Corps.

Personality
Flagon seemed to be a person who valued make things according to formal standards, since he opposed from the beginning to accept Levi and his friends into the Survey Corps due to their past as thugs, and scolded Levi for not holding the blades in the usual way. However, he aknowledged Levi's skills after seeing his abilities in action. Shortly before his death, he expressed his understanding of Erwin's motives for recruiting them.

Story
Flagon was first seen in a reunion between the leaders of the Survey Corps, opposing to Erwin's proposal to recruit Levi, Farlan and Isabel, believing that the soldiers' morale would be tainted if they were allowed. He showed a dissapointed expression after Keith Shadis accepted the proposal despite his complaints.

When Keith assigned the trio to his squad, he again showed displeasure and asked why they were not assigned to Erwin's squad, but Keith replied that Erwin was already tasked with the soldiers' formation. Flagon then led the new recruits to their room, and requested them to try to keep the place clean, insinuating that they didn't have good hygiene because they had been living in the underground. This angered Levi, who was actually a clean freak and had just found dirt behind one of the beds.

Levi gave him a menacing look, scaring Flagon, who asked how he dare to approach a superior officer with that attitude. However, Farlan intervened and offer Flagon an apology, and the latter leaves after informing them of their tomorrow's training and scolding Farlan for not making the salute correctly.

The next day, during Levi's training, he again scolded Levi for not holding the blades in the proper way and asked if he wanted to die, though Levi replied that Flagon might be the dead and said he will do it in his way, leaving Flagon angry. After Levi showed his abilities in 3D Maneuver Gear and the effectiveness of his particular style, Flagon was seen impressed.

The 23rd Expedition beyond the Walls began and Flagon was riding right behind Erwin. Three Titans pursued them and Flagon shot the flare at Erwin's orders. One of the soldiers was killed by a Titan, and an angered Flagon killed it. He then warned Levi, Farlan and Isabel to stay their course, but they disobeyed him and killed the other two Titans. He was then seen standing next to a subordinate, admitting that he now understood why Erwin was so insistent on having them join.

After many of the soldiers were attacked by a Deviant Type Titan, Flagon's split body was found by Erwin among the victims.
