"If they call you Chainsaw Man, that'd make me... Sword Man."

"Sword Man" (ソードマン, Sōdoman) is a human-devil hybrid that merged with the Longsword Devil and serves as a minor antagonist in the Control Devil arc, where he faces the Chainsaw Devil.

He returns in the Current arc of the Academy Saga as a supporting character.

Human Form
In his human form, Sword Man is a young man of average height with unkempt black hair and visible dark circles under his brown eyes. He wears a dark blue drawstring hoodie underneath his Fourth East High School uniform. During his time as one of Makima's brainwashed servants, he wore the Public Safety Devil Hunter suit.

Hybrid Form
When transformed, Sword Man gains a head similar to that of Katana Man, except that it has a pointed face from which two longswords protrude backwards, resembling horns. Sword Man's arms have blades protruding from them.

Personality
Initially, Sword Man's real personality was unknown due to being brainwashed and mind-controlled by Makima, although it seemed like he enjoyed attention as he wanted to impress Makima.

Post-mind control, Sword Man does seem to be fairly regretful for his actions during the fight, as he was able to seek out Denji to talk to him in private and empathize with his current situation. However, he doesn't seem to fully trust Denji yet, as he introduces himself using a codename rather than his real name.

Control Devil arc
At an unknown point in time, Sword Man was brainwashed by Makima to serve her needs. He is summoned as part of Makima's newly-formed Special Division 5, a team of weapon hybrids created for the sole purpose of battling the fully-powered Chainsaw Devil. While under Makima's control, Sword Man tells the others that he wants to impress Makima on the group's first operation.

Once Makima commands Special Division 5 to attack, each member activates their weapon trigger, transforming into their Hybrid forms. They all leap from their respective spots to lunge straight towards Chainsaw Man. Before any of the Hybrids can land a single blow on him, they are blown back by Chainsaw Man leaping forward as he slices through Quanxi and Sword Man with one of his chainsaw legs.

The three crash through several skyscrapers before landing in an apartment complex. As he gets up, Chainsaw Man kneels over Quanxi and Sword Man's tattered bodies, clutching each of their severed heads before fighting the other Hybrids.

At some point in the future, Special Division 5's Hybrids are revived once more by Makima, who brings them all to a graveyard to confront Denji. Once Makima finishes monologuing her thoughts of erasing anything she dislikes to Pochita (who is disguised as Denji), Sword Man and the other Weapon Humans transform into their Hybrid forms for the final battle. Pochita starts by slamming his fists into the ground, lifting up a huge chunk of the ground to throw straight towards Makima using his chains.

Katana Man and Sword Man act first by leaping forward, both slicing the chunk of land and cutting it down into several dozen smaller chunks. However, the two are left vulnerable as Pochita falls towards them from behind the debris. Before the two Hybrids can act any further, Pochita swiftly uses his chainsaws to cut them both, defeating them in the process.

Current Arc
Several months later, Sword Man, now freed from his brainwashing, approaches Denji after the latter's disastrous "date" with Fumiko Mifune. He stares at a recruitment poster for the Chainsaw Man Church, expressing annoyance over the inclusion of some nobody next to Chainsaw Man.

Denji asks Sword Man why he's talking to him, to which he reveals that although they don't remember each other, the two have met before. Upon being questioned about who he is, the young man unhoods himself to Denji, introducing himself as "Sword Man".
