A Hastur is a boy from the Hastur alien species who grew up alongside Nyaruko and Cthuko at their shared space kindergarten and elementary school. Despite his delicate appearance, he's definitely male—Nyaruko and Cthuko both call him "Hasuta-kun" to make that clear.
Hastur's the powerhouse of the trio. He controls air and wind, and he's noticeably stronger than both Nyaruko and Cthuko combined. Back in space elementary school, he was basically the group's unofficial peacemaker, constantly breaking up their fights before things got too out of hand.
Character-wise, Hastur draws inspiration from two figures in The Cthulhu Mythos: Hastur "The Enigma" and Ithaqua, the wind deity. That dual influence shapes both his abilities and his general vibe.
