Miri Sugo

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

Miri Sugo (ミリ), also known as "Sword Man" (ソードマン), is a Devil-human Hybrid that merged with the Sword 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 as he 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 decisionmaking.

His idolisation of Chainsaw Man has also left him fairly unsociable and rude towards others that 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 behaviour" 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.

Control Devil arc
At an unknown point in time, Miri 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, Miri 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 Miri 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 Miri'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), Miri 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 Miri 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, Miri, 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 Miri 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".

Miri then goes on to attempt to jog Denji’s memory by explaining how they know each other. Denji is immediately dismissive of this and chooses to leave Miri to go to school. Later it is shown that Miri is in the same class as Denji. He states that he transferred to Denji’s school from Kanagawa. When he is introducing himself, he is shown to be rude to the other students, stating he’s not here to make friends. Immediately after taking his seat, he is surrounded by 3 girls from his class where he calls out for Denji to help him in getting rid of them.

Later on, Denji is shown on the rooftop of the school with Fumiko sitting on top of him. Miri has seemingly arranged a meeting between himself and Denji to deliver a message. He states that he is a messenger from the chainsaw man church and that the other weapon hybrids hold high ranking positions within the church. He came to ask Denji to join, presumably at the same positions the others are at. Denji is hesitant to accept this invitation. Miri tries to sympathize with Denji, talking to him about how their pasts are similar and how they were both used. Despite his best efforts, Denji initially rejects his offer, but a comment Miri makes about Denji being able to "sleep with all the women you want" if he joins, makes Denji rethink his choice. As Miri is shown walking down the stairs into the school, Denji appears in front of him, much to Miri’s surprise. Denji then proclaims that he went back on his last choice and instead now wants to join the Chainsaw Man Church.

Miri eats lunch alongside Barem, the Whip Hybrid and the Spear Hybrid as they discuss plans for bringing Chainsaw Man out of hiding. Barem notes that the church's followers will spend next day worshipping Chainsaw Man, meaning they wouldn't be hunting any devils. Therefore, many civilian and public safety devil hunters will attempt to fight the devils themselves, and the ensuing massacre will cause Chainsaw Man to come and kill the devils himself. Miri believes this plan goes too far just to draw Chainsaw Man out. The Whip Hybrid tells him that starting tomorrow, they are all weapons, and to discard all other thoughts. Miri objects, asserting that he's a human and can think for himself. Barem agrees, but also notes that they're all hybrids and devils as well. Since all these things were born to kill, Barem believes that God would forgive them for all the people they would kill tomorrow.
