Atomic Samurai and His Disciples

The group is a squad of Hero Association fighters built entirely around the sword. At its head stands the S-Class hero Atomic Samurai, whose given name is Kamikaze, and beneath him train three A-Class disciples: Iaian, Okamaitachi, and Bushidrill.

Each student is a gifted swordsman schooled directly by their master, sitting just under Sweet Mask in the A-Class order. By Fubuki's reckoning, every one of them would already hold an S-Class seat were it not for Sweet Mask blocking promotions.

The disciples repeatedly serve as frontline swordsmen in the series' largest crises. When the Dark Matter Thieves leveled A-City, Iaian saved a father and child from Melzargard, lost an arm in the fight, and was pulled to safety by his master. In the lead-up to the monster crackdown, the students waited out a Council of Swordmasters meeting before Atomic Samurai resolved to strike the Monster Association rather than chase Garou.

Inside the Monster Association headquarters, the three pupils clashed with Do-S's mind-controlled mercenaries, then cut down the Demon-level Devil Long Hair in a hard-fought bout. After Master Joe unleashed Evil Natural Water, the group was overwhelmed, leaving only Iaian conscious to warn Child Emperor and later slice through a barrier to rescue the fallen mercenaries. On the surface he alone remained battle-ready, joining Spring Mustachio to repel Homeless Emperor and fight Black Sperm's clones.

The roster is led by Atomic Samurai, with Iaian, Okamaitachi, and Bushidrill as his active students. A lighter moment in the Neo Heroes era shows the team's dynamic: after discussing Sweet Mask in the G-City mountains, they tracked down King to test his skill, cornering him at a Mouse Sushi shop. King talked his way clear, and when asked to slice an apple he simply failed to draw his blade and left, which Atomic Samurai chose to read as a cut so flawless the fruit never noticed it had been severed.
