I hadn't planned on going out... but I'll capture the Golden Chick myself.

Hairein in Large-Scale Invasion 16.[1]

Hairein anime (2)

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.[3]



Hairein appears to care about his brother's opinion as he asked for his thoughts on the invasion.


They appear to have a good relationship, but Hairein fears her cruel personality.[citation needed]

    • Diversionary and dividing tactics
    • His family
    • A peaceful life
  • Izumi's nickname to Hairein, Exciting Animal Bastard (わくわく動物野郎 Waku Waku Dōbutsu Yarō?), comes from the TV program Exciting Animal Land (Waku Waku Dōbutsu Rando?). As the name implies, it's a show about animals, which explains why the nickname was adapted to "Mr. Discovery Channel" in Viz's translation.
