Kamikaze (カミカゼ, Kamikaze)[3], also known by his hero alias Atomic Samurai (アトミック侍, Atomikku Zamurai), is the S-Class Rank 4 professional hero for the Hero Association.


Atomic Samurai has long black hair tied in a topknot with dark eyes and a prominent jawline. He has a small goatee and is usually seen chewing on a blade of grass. His attire consists of a hooded red cloak with an atom symbol on the back that's draped over his open black haori. Beneath the haori is a traditional, loose-fitting white robe tied with a white sash and two haori himos. He also sports a pair of swords in his waist tied on his left hip.


Atomic Samurai has a rather prideful personality, seen when he refused to shake Saitama's hand telling him that he only acknowledges the strong and saying that he would greet him only if he makes it to the higher ranks of S-Class indicated that he quite bias in term of perceive a person since he only looks at Saitama's appearance and rank not his inner power. He also appears to dislike being called old. Despite his prideful nature, he behaves humbly to those he respects. This is seen with Bang, a fellow hero whom he holds the utmost respect for, and also his fellow Master Swordsmen.

He is also eager to test his strength against strong opponents. As a result, he once thought of a challenge in order to find his path. He then chose King, who was known as "the strongest man on earth". The challenge was proposed out of curiosity about King fighting style as well, since it was largely unknown to him.

He has the tendency to perceive people by asking them to use his sword to cut an apple. However, he is also shown to be quite naive, foolish and even delusional in term of perceiving a person at the same time since he thinks King is extremely powerful despite the obvious fact King cannot even cut an apple nor pull the katana out of a sheath. This indicated that he is highly lack of perception and often judges people based on reputation alone rather than watching their actions.


Hero Association SagaEdit

Alien Conquerors ArcEdit


Atomic Samurai greeting the heroes

Atomic Samurai first greets Bang, Genos, and Saitama enthusiastically as they arrive at the Hero Association meeting, although he notes that he does not know who Saitama is. Bang likewise acknowledges him and Saitama moves to shake his hand, which Atomic Samurai deftly denies, stating that he will acknowledge Saitama only when he has made it up to S-Class on his own.[4]During the meeting, Atomic Samurai wonders if Bang will teach Saitama and Genos martial arts, thinking that they will make decent rivals for his own disciples.[5]


Atomic Samurai fighting Melzalgald

Later, after A-City and a would-be opponent Sky King are destroyed by the newly arrived Dark Matter Thieves, Atomic Samurai's disciple Iaian enters a skirmish with Melzalgald.[6] After Iaian loses his left arm, Atomic Samurai intervenes by attacking the alien. Realizing the heavy wound of his disciple, he vows to not allow Iaian's swordsmanship to end in this tragic way.[7]

Atomic Samurai then engages Melzalgald in combat alongside Bang, Metal Bat and Puri-Puri-Prisoner. During their fight against Melzalgald, Metal Bat exposes its weakness by destroying the vital marble that allows him to regenerate, thereby allowing the four S-Class heroes to successfully counterattack.[8] However during the battle, Atomic Samurai is surprised to see Bang, who was caught off guard during his counterattack, get sent flying across the battlefield by a direct blow received from the monstrous alien.[9] When Bang got up unhurt, Atomic Samurai slashed the monster and Bang destroyed the last marble inside.[10]


Atomic Samurai criticized by Sweet Mask

After the monster was defeated, the spaceship that was above them started to crash down. Atomic Samurai helped Iaian run towards the Hero Association Headquarters.[11] Sweet Mask appears, demanding an explanation on why the city is in ruins. Atomic Samurai explains what happened, but wasn't good enough for Sweet Mask.[12]

Human Monster SagaEdit

Monster Association ArcEdit

Kamikaze attends a meeting of the Council of Swordmasters. At the meeting Atomic Samurai asks the council members for help in catching and killing Garou in worries that Bang might fail and die. The council members agree, except Haragiri who mocks Atomic Samurai's plea. Haragiri proceeds to show them the Monster Cells and reveals he had received them from the Monster Association and transforms into a Mysterious Being himself. Haragiri then orders the other to eat the cells or he will kill them, but Atomic Samurai cuts him first, killing him.

The following section contains Webcomic spoilers. You have been warned, manga-only readers.

He accompanies the other S-Class heroes against the Monster Association. He gets defeated by Black Sperm.

Fall of the Hero Association ArcEdit

Atomic Samurai talks with Bang about Bang's retirement. He is shown thinking about what he will do without Bang, and questions if he should try his luck with Saitama.

He is later seen in M-city looking for King for a duel, however, he cannot find him and proceeds to have sushi with his disciples. During the meal, he meets King at the restaurant and provokes him into a fight. After hearing the ''King Engine'', he and his disciples mistakenly believe King is in battle-ready formation. During this time, King is choked because of fear, which is further misinterpreted by the others as boldness.

Fortunately for King, Kamikaze puts his sword down and praises King's boldness not before slicing an apple into pieces. After that, he forces King to go outside and begin to fight. However, during the fight, King begins to bluff nonsense about a non-existent atomic reaction, which confuses him and his disciples. At the end of his speech, King walks away and tells Kamikaze not to perform his attack since it can lead to casualty, something which the heroes don't want to happen. As the result, Kamikaze puts down his sword.

Despite that, Kamikaze urges King to cut an apple with his Katana to determine King's life and power. However, King is too nervous, scared, and weak to even pull the sword out of the sheath. As a result, King delays cutting the apple for several minutes and ultimately puts down the sword to walk away in shame. Fortunately. Kamikaze's delusions about King's reputation and power kick in and he incorrectly deduces that King cut the apple at the cellular level, faster than he can even see, stating that the apple "does not even know it has been cut."

In the end, Kamikaze praises King's fake power and asks his students to join him in honing their swordsmanship in basic training since he thinks he needs to practice more in order to surpass King. Meanwhile, King walks away in shock and anguish.

Appearance in Other MediaEdit


The Murder Case that Is Too ImpossibleEdit

Heroes in spring

Atomic Samurai at the hot spring

Atomic Samurai, his student Iaian and other S-Class heroes were invited to a hot spring resort, after the Dark Matter Thieves failed invasion. While enjoying himself at the hot spring, he wasn't satisfied that some of the heroes that did not participate in the battle were invited to the resort, but Bang managed to calm down the situation. The next day after the ceremony, the heroes find Zombieman murdered, stabbed in the back by Atomic Samurai's katana.

Child Emperor saw him as the primary suspect, but Atomic Samurai had many alibis including Tanktop Master and Sitch, so all suspicions were dropped. While the investigation wasn't progressing, Tatsumaki tried to restrain everyone, until Zombieman suddenly woke up. Zombieman later revealed that Atomic Samurai's katana was floating with green light surrounding it similar to Tatsumaki, when it stabbed him. Zombieman didn't care what happened the night prior and the heroes disbanded.[13]

Relationships Edit

Bang Edit

Out of every hero in the Hero Association, Atomic Samurai only acknowledges and holds a deep respect for Bang. He once stated to Saitama that he only acknowledges the strong, which could be a reason for Atomic Samurai's respect to Bang, who is one rank above Atomic Samurai. His relationship with Bang is friendly, with a tad bit of rivalry between them, though this mild rivalry appears to be one-sided as Bang doesn't view Atomic Samurai as a rival. He also displayed concern for Bang when he was struck by Melzalgald.

Iaian Edit

Iaian is Atomic Samurai's best student and junior hero to his master. As a master, Atomic Samurai tries to maintain an image as a role model to his students, wanting Iaian to have faith in him and his abilities. He also looks out for Iaian's well-being. He made sure Iaian was alright during the Alien Invasion, encouraged him to not give up as a swordsman after losing his arm, and helped him run from the collapsing spaceship. Atomic Samurai also appears to treat Iaian casually, calling him by his nickname, 'Iai'.

Iaian holds respect to his master and also looks out for his well-being. He takes pride being Atomic Samurai's number one student, wanting to make his master proud by going after Garou by himself. Despite his admiration for his master, he gets annoyed at his master's habit of not listening to him.

Saitama Edit

Due to his pride for only acknowledging the strong based on current appearance and reputation, Atomic Samurai doesn't treat Saitama with proper mannerisms or respect.

Council of Swordmasters Edit

Atomic Samurai holds deep respect for his fellow swordmasters.

Sweet Mask Edit

Despite him being the reason his top disciples aren't in S-Class, Atomic Samurai thinks Sweet Massk is just a pompous blowhard, but admits his strength after seeing him fight Black Sperm.

King Edit

Kamikaze holds respect against King, however, he is not above challenge King to test his own strength. At the same time, he wants to know King's fighting style since he never witness King fights any monsters. However, he is also easily being swayed by King nonsense bluffing. In the end, he eventually makes himself into a fool by assuming King's cowardice and lack of power as extreme power that can surpass him by foolishly concluding that King can cut an object at cellular level despite the obvious fact King cannot even pull the katana out of the sheath to cut a simple apple.

Abilities and PowersEdit

Atomic Samurai is one of the top S-Class heroes and is considered to be one of the most powerful. He is reported to be the strongest backup hero. According to Superalloy Darkshine, if Garou were to fight him, he would most likely die before being able to show any of his techniques. He has the ability to perceive the person life by asking them to cut an apple, which is the method he uses to recruit his three disciples. However, he lacks the perception to see the inner human of a person and often being swayed by reputation rather than actions of a person.

Physical AbilitiesEdit

Immense Speed and Reflexes: Atomic Samurai possesses extreme levels of speed, being able to cut his opponents to pieces in the blink of an eye using his sword. He was also able to dodge Evil Natural Water's attacks, which were stated to be as fast as bullets. Other than that, he was able to counter many of Melzalgald's attacks, which were extremely quick.

Immense Strength: Atomic Samurai appears to have an extreme deal of strength, as he is able to easily cut through solid matter with his sword, as well as creating a powerful shockwave with a single slash. His strength is said to be "nuclear-powered".[2]

Fighting StyleEdit


Atomic Slash

Master Swordsman: Atomic Samurai has shown to be a formidable swordsman. His sword attacks are so fast and strong that the enemies are slashed into many pieces in an instant without even being able to react. Not even Disaster Level Dragon monsters such as Melzalgald and Black Sperm managed to defend from them. However, his swordsmanship has a limit since he cannot slide through the gap between cells and he can only prevent his sword from cutting blood vessels or organs not atoms.

  • Atomic Slash (アトミック斬, Atomikku Zan): Atomic Samurai's signature attack. He performs a number of quick sword slashes, leaving his opponents literally in pieces. He primarily uses this technique while moving past the opponent, but has also shown a stationary version in which slashes everything around himself.

Miscellaneous Abilities Edit

Master Teacher: Atomic Samurai is shown to be very skilled at instructing and raising disciples in the art of the sword. This is demonstrated by his three disciples whom are at the top of the A-Class rank of the Hero Association right underneath Sweet Mask himself and according to Fubuki if it weren't for Sweet Mask then his three disciples would already be in S-Class.


Katana: Atomic Samurai carries two katana. His primary one has a black hilt with a cross-guard that resembles the Rutherford atom model.
