Nagi is the Grand Duke of Artai and Nina's master. In the anime version: He enjoys teasing Mashiro and seems to know exactly what buttons to press to get his way. Upon his first meeting with Mashiro, he asked her if she was the "fake princess of Windbloom." Since then, the two have had a love-hate relationship. He's even had proposed marriage to Mashiro and nearly kissed her except for Arika's interference. His plan is to marry Mashiro and uses her power to rule the world, as a classical villain. For this purpose founds a army of traitor otomes who bear a grudge against Garderobe and the kingdom, where the only exception is Nina, who needs to work for him because she's his otome anyway. Nagi makes Nina and Arika fight each other, but in the end both give up because they're truly friends who love each other. The war stops and one of the last scenes shows us Nagi in the prision. In the manga version: In the manga version, Nagi is truly in love for Mashiro, not knowing that his beloved princess is actually a guy. He is used as scapegoat by the real villain who wants to kill Mashiro-boy and blame Nagi. When Sergay starts his dark plan to kill Mashiro-boy, he traps both Nagi and Mashiro in Garderobe's basement, where he reveals that he plans to kill Mashiro-boy and use the real mashiro princess, who wasn't really dead, as his puppet to rule the kingdom. When Mashiro is attacked, his clothes are ripped and Nagi discovers that his love is actually a boy, however he gives Mashiro his own jacket and says that, for him, it doesn't matter if Mashiro is a boy or a girl, he still loves him. Short after, Sergay kills Nagi and rushes to start a war in the kingdom, while Mashiro, wearing Nagi's jacket, declares that he will stops him. One of the last scenes of the manga shows Nagi and the real princess Mashiro in heaven watching Mashiro-boy and the other otomes having fun.

Constantly loyal to Nadia, his compassion slowly transforms her as a person, inspiring her to be trusting and faithful in others.

Captain, as he's known by his fellows, is a mercenary under contract with the Extra Order Company, a private security firm that was contracted by Kageyama of Asahi Heavy Industries. His job – eliminate the Lagoon Company, as well as their hostage Rock, mainly because of the computer disc Rock was carrying when he was taken. A veteran of the Liberian Civil War of the 1990's, Captain is an experienced soldier, with no qualms about killing anyone he was hired to kill. He's also a thrill-seeker, always looking for a worthy opponent to face-off against – which proved to be his undoing. The first attack against the Lagoon Company was at the Yellow Flag Bar. Captain and his fellows staged a hit from outside, killing most of the patrons. What they didn't count-on was Revy and Dutch, as well as a very irate Bao (because his bar was getting shot-up and threatening to make the Lagoon Company pay for the repairs and restocking), making a counter attack, killing sixteen of the mercenaries and wounding eight. The way the EO mercenaries were defeated impressed Captain, and he eagerly awaited another chance to face them. Later, while acting as the gunner of a modified Soviet Union-era Mil Mi-24 'Hind' helicopter gunship, he chased the Black Lagoon into the mouth of a river that had a dead-end, then waited for them to return so that he could kill them. What he didn't count-on was that Rock had formulated a risky plan to save his captors. In facing-off the gunship, the Black Lagoon used the sunken hulk of an old warship as a ramp and went airborne – with the gunship in front of them. Dutch, piloting the PT boat, then launched two of the torpedoes at it – with the fatal one hitting Captain square in the face before bringing the gunship down! (source: Absolute Anime)
