Miri Sugo

"If they call you Chainsaw Man, that'd make me... Sword Man. Let’s go with that."

Miri Sugo (ミリ), also known as "Sword Man" (ソードマン), is a Devil-human 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
Miri 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. His human appearance is noted as looking halfway between Denji and Haruka by his fellow students.

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

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

Post-mind control, Miri 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. His regret stems from how he allowed himself to be manipulated by Makima, similar to Denji, and as of such not only does he highly value his newfound free will, but he also wants to befriend Denji due to their similar circumstances. Despite his best intentions, however, others such as Fumiko have noted how he still seems to be prone to being manipulated by others, despite his insistence that the opposite is true.

He is shown to easily fall for the Church's conspiracy theories. When Denji, the real Chainsaw Man, tells him that those are lies, Miri admits that the Church may not be fully honest but that it saved many people regardless and that the ends justify the means, therefore proving Fumiko's point. Denji's words do seem to have influenced him somewhat, as he's later seen questioning their decision-making.

His idolization of Chainsaw Man has also left him fairly unsociable and rude towards others who aren't Denji. Upon transferring to Fourth East High School, he immediately announces that he isn't intending on making friends and calls the students trash to their faces. When the female students give him unwanted attention regardless, he is annoyed and asks Denji to make them go away. Despite his attempts to befriend Denji, he seems to draw the line at "infantile behavior" such as Denji and Mifune talking about what food they'd be able to eat forever rather than discussing his offer.

Out of the four known members of "The Weapons", he alone seems to have the strongest moral compass, as he's shown to be heavily hesitant towards their plan to carry out mass murder in hopes of drawing Chainsaw Man out from hiding. He refuses the Whip Hybrid's idea that they were merely weapons, insisting that he is a human and he should think for himself.
