Queen Reiko (common name Reiko Yamato) was Queen Consort of Bonaparte and the wife of King Yanuhito. She met the future king when she was a police officer in New Tokyo. At the time Yanuhito inherited the throne from Queen Qihong, Reiko led that city’s Homicide Division.
In 433 IE, she traveled to Mud to inform the Windsor heir to the throne, Edward Windsor at the end of Yanuhito’s reign. She also had the unhappy duty to inform Mitsuko Yamato that her great uncle Yoshi (Yanuhito’s common name) had passed.
When the Queen Maria Sophia came under attack, she and Elizabeth, as well as the new king, had to evacuate with Austin and Mitsuko as escorts. The group resisted allowing Edward to assume command, but relented when attack mechs boarded the ship. Reiko expressed impatience with Austin’s caution, but Austin refused to break combat protocol. When the group stopped in the ship’s armory for more appropriate weaponry, she actually schooled Chief Gannek on energy pistol usage and recited how to use Gelt stun grenades. She actively participated in shooting mechs as they escaped to JT’s Falcon, the CJC-1967.
Reiko escaped aboard the CJC-1967 to Mud. After JT and Edward negotiated a truce, she accompanied both sides to a cave north of the battlefield. She was present when they discovered the giant and Elizabeth explained its origins. While the Juno terrorists bombed the human and Gelt emplacements, Reiko spent most of her time meditating, seemingly bored with the whole situation.
After escaping Mud and the retaking of the Sophie, she traveled to Hanar as part of Edward’s party. At a state breakfast, Lattus Tishla proposed Edward join with Hanar instead of signing the most recent Compact revision. She did not hide her possible involvement in that discussion.
Later, she attended a dinner hosted by Edward for his party and the crew of the Goldeneye. When JT muttered something about Boolay wearing clothes, Reiko joked that she wanted to see his anatomy. She also needled Gav about his tendency to reshuffle the utensils, telling him Iron Cloud had been the last monarch to behead anyone over bad table manners.
On Amargosa, Reiko would accompany Edward and Mitsuko to the Thulian Clinic. Kept from the public, Bonapartan monarchs had been permanently rejuved since the inception of the world. Over a set number of years, they would display the effects of aging then “die.” Yanuhito awaited her.
During the trip, Reiko’s suspicions against Elizabeth came to the surface when she pulled an Etruscan stun wand. When Elizabeth began speaking strangely and made clear moves to self-detonate, Reiko pulled the stun wand and plunged it into Elizabeth’s belly, neutralizing the incendiary nanites and disabling the would-be assassin.
