A laboratory, a place where Fumiya was born. Without memories of his parents.When Fumiya was younger, he was under 10 years old and distinctly remembers living with his older sister, who doted on him. Fumiya engaged in various activities such as reading, writing, solving puzzles given by his sister, and even imitating martial arts movements from television and books.This is where her sister saw potential in Fumiya, so she made a hologram in the shape of a human to accompany him to practice.
Over time, Fumiya became interested in becoming a private investigator because he thought it was cool. His older sister was happy to support her brother's dream.When Fumiya was just 15 years old, his older sister made the bold decision to take him out of his comfort zone and relocate to Tokyo. Despite Fumiya's inquiries, his sister remained tight-lipped about their sudden move.
She was determined to provide Fumiya with a comprehensive education, ensuring that he completed his studies and eventually graduated with a law degree.This educational background provided Fumiya with the foundational knowledge and skills to pursue his dream as a private investigator.
Now that her brother's dream had come true, she gave him AI ROBOT as a memento before she went missing.[Updated]
