Atomic Samurai and His Disciples are a group of heroes who specialize in swordsmanship. The team consists of the S-Class hero Atomic Samurai and his A-Class disciples Iaian, Okamaitachi, and Bushidrill.
Atomic Samurai's disciples are all skillful swordsmen under the tutelage of the hero and rank just below Sweet Mask in the A-Class rankings. According to Fubuki, all of the disciples would be in S-Class if it weren't for Sweet Mask's gatekeeping.

Iaian accompanies Atomic Samurai to the Hero Association Headquarters in A-City, when the city is suddenly demolished by the Dark Matter Thieves. He manages to save a father and child from Melzargard. One of Melzargard's attacks tears Iaian's arm off. He is saved by his master and is ordered to stop bleeding. Iaian later observes the fight between Melzargard and the heroes Atomic Samurai, Bang, Puri-Puri Prisoner and Metal Bat. Seeing their attacks do nothing to Melzargard, Iaian tells them to retreat and find a solution to defeat it, but his pleas are ignored. After the monster is defeated, Atomic Samurai helps Iaian retreat to safety.
