Nyaruko

Nyaruko is the titular protagonist from the Haiyore! Nyaruko-san anime and light novels.

Nyaruko is an Outer God who is sent by Azathoth to protect Mahiro Yasaka. Nyarlathotep is an outer god. She is sent by the Outer Gods to Earth in order to protect a human named Mahiro Yasaka. Nyarlathotep quickly falls in love with him though which she refers to as "love at first sight". Her feelings towards Mahiro become serious with him going so far as eventually talking about marriage and a family together. She takes the form of a human girl with long silver-colored hair, but says to Mahiro that she can change to her original form if he wants him to.

Her actual age is unknown since ahe always stops Mahiro whenever he becomes curious or questions her age. When it comes to education she stated to Mahiro that she is a being of infinite knowledge and wisdom, spawn from the blind idiot god Azathoth himself, who's dream we all live in and who's mercy we are all at, and it is insulting that a mere mortal would ask such a pitiful question. She joins Mahiro at his school in order to get closer to him. Nyarlathotep is shown to be highly into gaming, and says that Earth's entertainment is well known to the outer gods.

Appearance
Nyaruko takes the form of a human girl with waist-length silver-brown hair and has green eyes.

Personality
She is always friendly to Mahiro, eager to pursue him, but often shows abusive and brutal habits to any hostile aliens. She is also obsessed with otaku culture. She takes the name Nyaruko Yasaka as Mahiro's cousin when staying at Mahiro's house and attending his school. Her actual age is unknown since she and Kūko always stop Mahiro whenever he becomes curious or questions her age, although she states that she has already graduated from space college. She happens to be smart and self-confident, as she graduated from one of the best universities at the top of her class, and entered the Space Defence Agency after her exam. She is also quite wealthy, capable of spending a lot on otaku-related products.

Abilities
As a top agent, she mainly uses space CQC to fight (note that the definition of "space CQC" is defined by the user and is not restricted to close quarter combat weapons). She claims to be one of the best fighters on Earth, as she states that her combat level is 530,000, while a normal farmer armed with a hunting rifle is 5 (though this may be a parody of Dragonball Z). Despite this, she is always unsuccessful when dodging Mahiro's fork attacks. She shows fourth wall awareness in the first episode of the second season of the anime.
