Description
Hasuta is a Hasturan alien from the planet Hastur, originating from the Cthulhu Mythos as an interpretation of the King in Yellow character later incorporated into Lovecraftian lore. He attended space elementary school with Nyaruko and Kuuko, frequently mediating their conflicts and establishing himself as stronger than both even in childhood. His background includes being the son of the owner of Carcosa Computer Entertainment (CCE), a prominent space-based video game company modeled after Sony Computer Entertainment. Initially sent to Earth to gather intelligence on human entertainment from Yoriko Yasaka, he abandoned this mission after failing and chose to remain. He later joined the Space Defense Agency as an agent alongside Nyaruko and Kuuko, protecting against extraterrestrial threats.

Physically, Hasuta presents a youthful, androgynous appearance often mistaken for a young girl. He has long blonde hair styled in a side plait on the right, two thin bunny ear-like ponytails atop his head, large aqua blue eyes, and a pale complexion. His typical attire consists of a hoodie, shorts, and sneakers, including during swimwear scenarios. A distinct power form alters his appearance to a more mature, masculine version, accompanied by a shift to a confident, assertive personality. This transformation is triggered by physical contact to his torso and involves noticeable discomfort.

His abilities center on aerokinesis, enabling combat techniques like generating strong winds, creating vacuum blades, and forming vacuum fields around opponents. These powers position him as a formidable fighter within the Space Defense Agency team.

Hasuta's interpersonal relationships include a close but occasionally combative dynamic with Nyaruko, whom he has placed in headlocks or kicked during conflicts. His relationship with Kuuko is less explored but generally amicable, with mutual care evidenced during emotional moments. He develops romantic feelings for Mahiro Yasaka, the human he protects, leading him to enroll in Mahiro's school under the alias Hasuta Yasaka. When Mahiro notes their gender difference, Hasuta affirms his affection regardless; Mahiro deflects the advance noncommittally. This infatuation manifests as persistent, occasionally obsessive behavior toward Mahiro. His relationship with Luhy Distone begins antagonistically when she associates him with his father but evolves into a nurturing, sibling-like bond where she provides care and companionship.

Personality-wise, his base form exhibits shyness, obedience, and notable innocence, being the only character never shown swearing at others. This contrasts sharply with his power form's maturity. His character arc involves transitioning from an intelligence-gathering mission to becoming an integrated Earth resident and protector, navigating relationships while concealing his alien identity at school.
