A Hastur (alien species), who attended the same space kindergarden and space elementary school with Nyaruko and Chtuko. Despite Hastur's appearance, Hastur is actually a boy. Nyaruko and Cthuko call him "Hasuta-kun". He possess the power of air, and is known to be stronger than both Nyaruko and Cthuko, since he was the one who always stopped their fight during space elementary school. Hastur is based on both on Hastur "The Enigma", as well as Ithaqua The deity of the wind. Both are from The Cthulhu Mythos.
