His father has been missing since his birth. As a result, he was nurtured and raised by his uncle Gamagoori, Kenkichi, a steel fabricator in Yokosuka, Japan.
His father is an American soldier deployed to
Yokosuka base, but a lot about him still remains a mystery. His mother is a nurse.
Growing up, he was a victim to bullying due to his mixed ethnicity. However, this changed when he was in 5th grade, as he pierced his ear after his uncle’s advice. (with it he changed his attitude)
His uncle designed the steel armor he used to challenge Satsuki in middle school days.
His uncle also designed a Titanium-based
Haramaki that is more than 10 times as strong as the one he made 5 years prior, post-Tri city conquest.
He sends majority of his school-provided expenses to his mother.
“Jakuzure, Nonon”
Her family runs Jakuzure Transportation, a company under Kiryuin conglomerates, and is in charge of handling REVOCS merchandises’ distribution and shipping supplies to associated factories worldwide.
Satsuki in kindergarten was a very well-disciplined child who always behaved and was constantly smiling. Nonon found her uninteresting at the time.
However, Satsuki changed toward the end of kindergarten, and Nonon began wanting to be with her and hold her hands.
In grade school, Nonon stood out more than Satsuki and was the queen of the academy. However, while Satsuki was always found alone and quiet in the corner of the classroom, she was actually the one controlling the academy in the background.
Nonon originally entered a very prestigious middle school that was only open to the upper-class families. However, since Satsuki entered Rinnedo middle school in Kanagawa, she transferred to the same school.
“Inumuta, Houka”
Following Tri city conquest, he learns that Public Safety Bureau of the Tokyo Metropolitan Police Department is investigating the Kiryuin conglomerates’ activities.
The deputy director of the Police Department is Houka’s father Inumuta, Akito.
His father has always been out of home since he was little, and his mother was dedicated to support the father-less house.
He developed his interest in computers when he was in grade school.
He’s been living alone since he entered middle school by illegaly overwriting his personal record stored in city authority’s servers.
He coded a program that automatically responds to emails his mother sends from time to time worrying about his living conditions.
In order to stop his father from further investigating Kiryuin conglomerates, Houka set up an embezzlement charge against him in an attempt to force him to resign from his deputy director’s position.
