Iaian

Iaian (イアイアン, Iaian) is the A-Class Rank 2 superhero and a disciple of Atomic Samurai.

Appearance
Iaian is a young man with a serious expression and short spiked hair. He wears a suit of armor with a katana at the waist.

Personality
Iaian is shown to be quick-tempered as witnessing the widespread destruction of A-city, an act he deems "unforgivable", enrages him. Also, upon being attacked by a mysterious alien, Iaian gives no quarter and responds immediately with an attack of his own.

Alien Conquerors Arc
After the destruction of A-City Iaian climbs out of the rubble only to see nothing standing in front of him but the Hero Association's Headquarters. As he is standing there a large creature appears behind him and attempts to crush his head. The creature only crushes his helmet, it's occupant having moved away in time. He states that there was no way he would not have noticed its killing intent and proceeds to attack the monster.

Abilities & Powers
Being a A-Class hero, Iaian is a rather powerful individual. It is also stated by Fubuki that he could be S-Class if it wasn't for Sweet Mask.

Swordsmanship
Being a disciple of Atomic Samurai, Iaian is extremely skilled with the sword. He has been shown to have a rather keen grasp of what is happening around him, easily avoiding an attack from a large monster and then returning a strike right after.

Trivia

 * Iaian's name is a Japanese portmanteau of "iai", a sword-based Japanese martial art, and "aian" or iron, referring to his armored appearance.
