He is Neighbor from Aftokrator, and the head of House Veltiston. He is a Black Trigger user and the captain of the group that invaded Earth.

Hairein is a tall neighbor with long, messy blue hair and neat blue eyes. Like all other Aftokrator Neighbors, he has two horns on his head. In the anime, he is portrayed with light blue-gray hair. 
According to Ashihara sensei's comment, his image of design is dragon.

Hairein has a careful and calculating personality, and is also shown to be a good strategist. He seems to be intent on fulfilling his group's goal. Despite this, he is a pacifist and fears Mira due to her sadistic personality. He appears to have a sense of ethics as he chose tactics which divided enemy forces and concentrated on capturing C-rank agents only.

One day, a gate to another world suddenly opens in Mikado City. Aliens invincible to Earth’s weapons, called “Neighbors”, start coming over. Earth’s only line of defense is a mysterious group called the “Border” who are armed with weapons called “Triggers”.<br>
 <br>
Four years later, the city has recovered from initial attacks and citizens of Mikado City have started to get used to the Neighbor’s attacks. Yuma Kuga, a transfer student, and his classmate Osamu Mikumo find themselves fighting a Neighbor that suddenly appears. Osamu, who is actually a Border agent, activates his Trigger but is unable to defeat it. This leaves Yuma to activate his own Trigger and defeat the alien. Yuma reveals that he is not part of Border and is actually a Neighbor who has transferred from the other side.<br>
