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 lacking in perception and often judges people based on reputation alone rather than watching their actions.

Abilities and PowersEdit

Atomic Samurai is one of the top S-Class heroes and is considered to be one of the most powerful. 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's 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 is often swayed by reputation rather than the 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 the only one capable of consistently dodging Evil Natural Water's attacks, which were stated to be faster than any speed that Child Emperor could process. Other than that, he was able to counter many of Melzargard's attacks, which were extremely quick. His amazing speed is shown again when he defeats a transformed Haragiri who was stated to be faster than the speed of sound at this point, Atomic Samurai ended his life so fast that Harigiri couldn't even react to it.

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 Melzargard 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 he 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.
