Kaiju number 8

Face and facial expressions: He has a so-called "fox-like" appearance. Most of the time, his eyes are closed or narrowed in a sly, relaxed smile. When he opens his eyes (for example, during serious battles), his expressive purple pupils become visible. When he smiles, small, sharp fangs are sometimes visible. Hair: Short, dark purple hair, styled in a neat and even bob with straight bangs that slightly cover his forehead. Build: At 171 cm tall, he has a slender, flexible, and toned athletic build. His figure is perfectly adapted to high speed, agility, and filigree mastery of bladed weapons. Clothing: He is most often seen wearing the standard, form-fitting combat uniform of the Defense Forces, black with white and gray elements. As weapons, he uses two specialized combat blades, which are worn on his back or on his belt.

Aoi is a tall, muscular young man with dark skin, short, spiky light-colored hair, red eyes that are noticeably lacking eyebrows, and a serious expression.[ 3 ]

When on duty, he wears the Defence Forces uniform, as well as a battle suit on the battlefield.[ 3 ]

Personality
Aoi is very serious, always striving to be on top and surpass his peers, doing whatever it takes to become stronger and surpass others.[3] Despite his sometimes cold nature, he hides much more of his emotions than he shows.[4] In fact, due to his prideful nature, he has a rivalry with Haruichi Izumo, another very capable student.

Haruichi is a tall young man with medium-length dark green hair that is tied into a half-bun with the rest of his hair left loose, large dark blue eyes and thin eyebrows, and he usually has a relaxed expression.[ 5 ]

When on duty, he wears the standard Defence Forces uniform and also wears a combat suit when engaged in combat.[ 7 ]

Personality
Haruichi is generally a calm boy with an observant and cunning personality.[ 5 ] Because of this, Haruichi tends to be more level-headed than his peers, preferring to observe the noise of others from the sidelines rather than getting involved in the chaos himself.

Iharu is a hot-tempered and prideful person who dislikes being inferior to others or losing, and constantly strives to surpass those he considers stronger than himself.[6] For this reason, he has set his sights on Reno Ichikawa, bragging about him at every opportunity.[6] Iharu is described as a stubborn character who lights up any environment he is around.[1]Iharu is a tall, athletic young man with messy pink hair shaved to the side, orange eyes, and sharp teeth.[3]

In combat, Iharu wears the standard Defense Forces combat suit[5], as well as the regular uniform while on duty.

Reno is a tall, slender young man with short silver hair and large violet eyes. His face usually has a neutral, unflappable expression, but in Kafka's presence, this expression changes to irritation or distrust. Reno is a calm and level-headed person. Despite his initial dislike of Kafka for giving up on his dream, he later reveals a softer, more caring side toward his friend, his condition, and his goals. As their bond deepens, Reno begins to display a protective side not only toward Kafka, but toward all his comrades.

Mina is a serious and determined woman who takes her job and role in the Defense Forces very seriously. She strives to keep the promise she made as a child to defeat every kaiju, dedicating herself entirely to fighting them. Despite her professional demeanor, she harbors tender feelings for Kafka Hibino: although she was upset that he failed to keep his promise to be by her side, she fondly remembers their friendship and wishes him success in the Defense Forces, even after learning that he is Kaiju No. 8. Mina is a beautiful young woman with waist-length black hair pulled back into a ponytail and adorned with a hair clip, large dark orange eyes with a mole under each eye, and an athletic build.[1] Under her uniform, she has a small scar on the left side of her upper chest.

Kikoru is portrayed as an arrogant and prideful girl,[2] who is very confident in her ability to look down on people and belittle those she considers beneath her without a second thought.[5][16] Kikoru is also very persistent and driven, constantly working to improve herself and become stronger and more helpful whenever possible. Kikoru is a petite and rather short young girl with long blonde hair tied into two pigtails on the sides, adorned with two black bows, large green eyes, and a rather thin yet athletic build.[2] Given her appearance and hair, she greatly resembles her mother, Hikari Shinomiya.[12]

On duty, Kikoru wears a standard Defense Forces combat suit along with her usual arsenal.[ 13 ] With her new personal weapon, "Weapon Number 4," Kikoru dons a light-colored scale suit with a long skirt.

Kafka's Kaiju form is primarily covered in jet-black scales and plates, with turquoise energy occasionally escaping from cracks (especially when preparing a powerful attack). However, its head, spine, and collarbones appear to be made of exposed bone, giving these features a contrasting white color. Large plates with dorsal spikes cover the back of its head and neck above the shoulders, with the uppermost portion being white. Its head is described as a "demonic skull-like face" with two short, thick horns, a hole in place of a nose, and sharp, exposed teeth that extend down its neck. Its eyes have black sclera with turquoise irises. Kafka appears to have several cracks running from them, and his left eye is missing several pieces of the "mask" in the lower left side. Kafka is a tall man with dark brown spiky hair, large eyes with small irises, thin eyebrows, and a light goatee on his chin; he has a fairly muscular build, save for a slightly chubby belly, and usually has a cheerful expression. Kafka has a comically childish personality in most situations, making him an easy target for ridicule from others, despite being a determined and dedicated person in serious situations, who tries his best to succeed both individually[1] and for the good of the group[15]. Kafka was also a genuinely caring and kind guy long before he joined the Defense Forces, and as such, he would go out of his way to help and care for others, whether they want it or not.
