Born into a prestigious family, it was decided that he would follow his father's footsteps with his life was all devoted to studies, devoid of anime and hobbies. This continued until he was 7 years old when he met Toru, a boy of the same age as him, who brought him into the world of Gunpla Battles. Eventually, he was engrossed into Gunpla and became a proficient builder and fighter while constructing his first customized Gunpla; the ν Gundam Brave.

[Spoiler] Sometime after being introduced to Gunpla, he was pressured into going abroad to study before inheriting his step-father's company. While studying in London, he was prohibited from building or playing Gunpla. At first he was resentful at all the pressure being mounted onto him but his love for Gunpla and the freedom that came with it was rekindled when he met Sei's father, Takeshi Iori. [/Spoiler]
