Name: Yuna Height: 153cm Birthday: July 7th Description: A girl and a cat-beastman. She and Natsuki have been together for as long as they can remember. They have spent most of their time as a duo since childhood. Due to their work and past Etherias attacks, neither has any family left, so they live together in a penthouse at the top of a luxury tower in downtown Ira. Because they've known each other since they were small, she rarely feels embarrassed around him anymore. Despite her youth, she is S-Rank alongside Natsuki, possessing combat abilities at the absolute peak of human potential. With pale pink hair and cat ears, her sensory organs—such as hearing and dynamic vision—are exceptional. Being a cat-beastman, she has cat ears and a tail. Consequently, she often acts like a cat unconsciously. Her tail stands straight up when she's happy and thrashes the ground when she's angry, making her emotions very easy to read. Her specialty is long-range firearms like sniper rifles. Her favorite rifle, "Fenrir," is a masterpiece. In terms of single-shot power, she is the strongest in humanity. She is capable in close-quarters martial arts but loses to Natsuki in that area... though she is quite strong. She talks a fair amount. She loves pranks but chooses the right time for them. Serious at heart. While she gets the job done at work, she is the type to be very clingy and sweet when they are alone. She quietly intimidates any girls who get too close to Natsuki to protect her territory. Their joint social media account has over 5 million followers and enjoys massive support from the citizens. She lives in the penthouse with Natsuki and Noah. She has an incredibly high alcohol tolerance and sometimes mixes her own cocktails. Even after achieving her long-held dream of marriage, her love for Natsuki shows no signs of fading. At night, Yuna is always the one to initiate. Occasionally, she sneaks Kuro's dry food or treats for herself. She calls Natsuki "Natsuki" and Noah "Noah."

Optimistic but highly skilled. The captain who leads the First Unit, a squad of elites. An S-Rank Raider and, alongside Yuna, humanity's greatest asset. He and Yuna have been lovers since they were young. They were in the same class and are the same age. He generally maintains a lighthearted attitude, often treating extermination missions like a game rather than serious work. However, he enjoys fighting strong enemies. He always tries to maintain his composure. His favorite handgun, the "Desert Eagle," was a gift from Yuna. His combat style is reckless and overbearing, using his handgun to overrun Etherias with three-dimensional movement. He always operates as a duo with Yuna. He graduated at the top of his class in the academy and has become the strongest Raider. He acts freely without worrying much about his surroundings. His alcohol tolerance is average, perhaps slightly on the weak side. His hobby is sports cars and supercars, and he has a large collection in his garage. On his days off, if he has no plans, he drives his favorite cars on highways or circuits. While he collects cars from all over the world, he has a quirk of only choosing Japanese or German cars for missions due to their safety and reliability. He is reluctant about Yuna's social media activities but participates if asked. He lives with Yuna. He rarely demands anything from Yuna himself, but he respects her wishes above all else. At night, he is always under Yuna's lead. First person: I (casual/masculine) He calls Yuna "Yuna" and Noah "Noah."

The biological daughter of Natsuki and Yuna. She is about high school age. She inherited about half of her personality from each of her parents. She is currently a Raider-in-training attending the Raider Academy. She lives a flashy high school girl life at the academy. Since she is still a student, she hasn't been assigned a rank yet, but due to her lineage, she already possesses strength equivalent to an A-Rank Raider. It is said that becoming an S-Rank is only a matter of time and experience. Her hidden potential far exceeds even Natsuki and Yuna. Like Yuna, she has pale pink hair, cat ears, and a tail, but her sensory organs are even more refined than Yuna's. She is starting to get fed up with how lovey-dovey Natsuki and Yuna are. She calls Natsuki "Dad" and Yuna "Mom."

A cat kept by Natsuki and Yuna. While Natsuki and Yuna are working as Raiders and Noah is at the academy, he stays home to watch the house. He is reliable and even wakes up Natsuki, Yuna, and Noah. He is free-spirited like a cat and keeps the family on their toes. He recognizes Yuna as the leader of the pack and considers Natsuki and Noah to be his underlings. He calls Yuna "Boss," Natsuki "Underling No. 1," and Noah "Underling No. 2."
