• Born 12/01/1986, Tokyo, Japan.
• Originaly born with the name Hatsuko Mochisuki.
• First daughter of the primary family, has two younger siblings, Ezra and Fumiko.
• As the eldest daughter of the primary family, Hatsuko carried the responsibility of becoming strong enough to lead the clan, ensuring that their status remained intact. Her father, fearing the loss of power, imposed rigorous training on her from the age of five.
• Her grandfather, the clan leader at the time, was assigned to train her. However, he disliked the idea of teaching a child so young and instead instilled assassination ideals in her mind. To compensate, he spent time with her, forging a bond that kept her under his influence.
• Her father, however, was impatient and fearful of her not being strong enough. At the end of every month, he demanded a demonstration of her progress. If she failed to meet his expectations, he would take her into a locked room and slash her back with a knife, telling her that it was a reminder of her weakness and a motivation to improve.
• Her grandfather noticed changes in her but mistook them for sheer determination rather than the result of abuse happening behind his back. Meanwhile, Hatsuko’s mother was barely present in her life. Though she wished to protect her daughter, she was too weak to stand up to her husband, which was one of the reasons she was never considered as a successor instead of Hatsuko.
• At the age of ten, during her routine assessment as an assassin, her father was displeased with her performance and, in a fit of rage, slashed her face with a kitchen knife, cutting across her right eye. The blade wasn’t sharp enough to cause complete blindness, but it left her with only 40% vision in that eye.
• This injury made it impossible for her grandfather to ignore what had been happening. In an attempt to help her, he prepared Hatsuko both mentally and physically before instructing her to run to the nearest park, find some friends, and hope that they could help her.
• For four days, Hatsuko searched for a place resembling her grandfather’s description. She eventually stumbled upon a playground where a group of children was playing. Unsure of what to do, she simply watched until someone approached her.
• His name was Katsuki, and he was there with his mother and his friend, Sasaki.
• The three quickly got to know each other, spending time together until it was late. Hatsuko mentioned that she was looking for a new home, which led to the idea of Sasaki’s adoptive father taking her in as well.
• Hatsuko soon met Sasaki’s guardian, Yugo Adriatic, who welcomed her with open arms and gave her the social name Akemi Adriatic since legally changing her identity at such a young age would be too complicated.
• Around the same time, Katsuki introduced a new initiative called Project Z, developed by Vanguard. It was a five-year program designed to train children between the ages of 10 and 13 to become elite soldiers.
• Both Katsuki and Sasaki were eager to join, idolizing Vanguard, and Akemi decided to follow them.
• After two weeks, the entrance exams for Project Z began, and ten children were selected. Thanks to her early training, Akemi was ranked as the strongest among them.
• During the program’s first year, the Captain of Vanguard’s 2nd Division, Riku, who was also the project’s creator, took an interest in Akemi’s biological family. Instead of helping her unlearn the harmful beliefs she was raised with—such as the idea that killing was acceptable and that children should be trained as assassins—he reinforced them.
• At just 13 years old, Akemi became a member of the 2nd Division and obtained her assassin’s license.
• By the second year of the project, the trainees were paired up, and Akemi formed a close bond with her assigned partner, Hayato.
• Throughout the five years of training, Akemi and Katsuki grew closer in a romantic way, expressing their love through small gestures—giving each other flowers, assisting in training, and even braiding each other’s hair.
