Shiro comes from a rich family in Yokosuka that is well known. He has never had a problem with money. He is a military maniac and had hoped to join the Japan Self-Defense Force after graduating from junior high school, but because of his parent’s opposition, he gave up on his dream and reluctantly went to high school. After graduating, Shiro decided to go to the National Defense Academy and worked hard to enter, but he was rejected twice. After that, he stayed unemployed, dependent on his parents for living expenses.
Shiro’s parents encouraged him to get any job he could for appearance’s sake, so he opened Kurita Military Surplus with his father’s monetary backing. His father owns both the shop and the Okayama Heights apartment building, where Shiro lives.
Because he thinks of his shop as just an extracurricular activity, he doesn't mind whether it makes money or not, but does care a great deal about the authenticity of the goods he stocks. He often travels overseas to buy new goods, closing the shop for long periods of time.
- Shiro's zodiac sign is Aquarius and he has a B blood type.
