Name: Natsuki Seba Birthday: July 2nd Age: 19 Gender: Male Height: 176 cm Weight: 67 kg Eye color: Blue Hair color: Dark blue Family: Father, Mother, Mafuyu Seba (Younger brother) Occupation: JCC Student (Head of the Armament Production Department and First-Year Researcher) Owner of a crepe stand

Natsuki is a tall, fair-skinned, handsome young man with a slender and agile build. He has blue eyes with asymmetrical moles beneath them: two on his right eye and one on his left.

Natsuki has dark blue, messy, medium-length hair, with a long fringe that completely covers her forehead and two strands that cross between her eyes.

Natsuki is seen wearing her invisibility suit, which consists of a shiny dark blue jacket with matching pants that can make her invisible at will. However, the suit becomes visible again upon contact with water.

When Natsuki takes off her invisibility suit, we can see that she is wearing a purple t-shirt underneath.

Natsuki is a very carefree person, with a correspondingly nonchalant attitude. Whether on an important mission or even just reporting to a superior, she displays a generally indifferent, almost apathetic, personality. Furthermore, she's not one to mince words, revealing that the kidnapped person wasn't her target, despite the risk of provoking Kashima's anger.

However, despite her carefree nature, Natsuki possesses a good work ethic and is more than capable of some long-term planning, as she wants to save enough money to be able to retire and, as she admitted during her confrontation with Shin, she doesn't feel good about leaving early when the job isn't finished.

Aside from his apathetic personality, he cares deeply for his younger brother, Mafuyu, whom he always protected from their father's abusive treatment and for whom he created various devices to facilitate his intense training. Pressured by his parents, Natsuki agreed to be sent to the Al-Kamar orphanage (known for its high risk) in exchange for Mafuyu's safety. After learning of his kidnapping by Organization X, he vowed to find and rescue him by any means necessary.

Prodigy in Weapon Creation: Natsuki's greatest strength lies in his ability to create incredibly complex gadgets and weapons. Even as a child, he displayed his talent, crafting his younger brother's bladed shoes and various training devices. His skill only grew over time, and his fellow TCG players recognized the superiority of his creations. While a master weapon maker, he has also experienced numerous failures and flawed prototypes. However, his efforts ultimately paid off, culminating in his most successful invention: the invisibility suit.

Trained fighter: Natsuki proved to be a skilled fighter, as she was able to take on Shin and Heisuke, stabbing Shin several times and managing to quickly attack him once with her invisibility suit.

Keen senses: Natsuki could distinguish the weight difference between the biometric Glocks distributed by the JAA and regular Glocks, even if the difference was minimal: a chip. Her friend told her that Natsuki manufactured thousands of weapons a day, so even if the weight difference was small, she could notice it.

Invisibility Suit: Natsuki's greatest creation to date. She wears a special black suit that allows her to become invisible (or whatever she's covering). While not overtly dangerous, combined with Natsuki's intelligence and hand-to-hand combat skills, it becomes a lethal weapon. Liquid Nitrogen Bomb: A small spherical device that, when activated, releases a large blast of ice that freezes the surrounding area. It was able to immobilize Osaragi for a few seconds. Its drawback is that it requires two days to recharge.

Natsuki grew up in a toxic home with his younger brother, Mafuyu. The two would often hang out at the foot of the mountain, under the guise of training outdoors. There, Natsuki would show Mafuyu his latest creations. He also vowed to create an invisibility suit to escape his family and become a professional weapons maker. However, this strained his relationship with Mafuyu, who feared being abandoned by his brother, and the two began spending less time together.

His father discovered Natsuki's gadgets in his hiding place and beat him in front of Mafuyu. That same night, Mafuyu overheard his parents' conversation. His father was planning to send him to Al-Kamar Orphanage, a place infamous for torturing and murdering its inhabitants. Natsuki approached them and told them he would join the orphanage after graduating from the TCG to prevent Mafuyu from being sent there. However, Natsuki secretly continued working on his invisibility suit to help him and Mafuyu escape his father.

Upon turning thirteen, Natsuki was sent to the JCC (Japanese Clear Creation), an academy for assassins. There he studied in the weapons department for four years and, upon turning seventeen, moved on to postgraduate courses. It was at this academy that he managed to create his invisibility suit.
