Ai

Ai (アイ, Ai) is a mysterious being and one of the Five Great Calamities that humanity met in the Dark Continent.

Appearance
Little is known of Ai's appearance, but it seems to be a gaseous life-form.

Background
When the Republic of Minho, after enlisting the help of the Hunters Association, sent an expedition to the Dark Continent searching for "the three primary liquids" they were surrounded by Ai. After a still unknown dispute or struggle ensued only three survivors returned, but empty-handed and without even a shred of their sanity.

Abilities & Powers
Not much is known about Ai's abilities, but, according to Ging Freecss, its threat level is either A or B, like that of the other Five Great Calamities. The current Chairman of the Hunters Association, Cheadle Yorkshire, proclaimed that their danger rank has been raised from B to A, which is even higher than that of the Chimera Ants. Due to the Minho incident and the fact that its full title reads "The Desire of Co-dependence gas life-forms Ai"(co-dependence being the enabling of poor mental health and well-being), it is possible that Ai is capable of making other creatures turn violent or go insane, but this has yet to be verified.

Trivia
