An eager young navy yeoman tries to impress exhausted Anna with the Thomas Prince and accepts her warmth as permission to relax protocol.
Jin Ichigawa is the young yeoman assigned to greet Anna Volovodov when her shuttle docks with the Thomas Prince. He pulls her baggage and enthusiastically explains the Xerxes-class dreadnought's dimensions, design lineage, shuttle capacity, thrust gravity, keel elevators, and naval terminology. His captain has ordered a complete VIP tour including the restricted bridge.
Anna is too exhausted after eighteen hours of hard burn to continue, but she lets Jin down gently and asks him to use her first name rather than a title. He reveals that he is Buddhist at his grandmother's home and a navy man everywhere else, joking that the navy considers itself a religion. He escorts her to her stateroom and assures her that she is aboard the safest place in the solar system.
Jin is a young male UN Navy yeoman, youthful enough to blush visibly at the back of his neck. His facial features, build, hair, and uniform details are not otherwise described.
Jin is Anna's first guide to the Prince, translating an intimidating war machine into the charming enthusiasm of one young sailor.
