Emeraldas is one of the few people who know the route of Count Mecha's Time Castle, and when her ship, the Queen Emereldas, appears next to the Galaxy Express, Tetsuro doesn't hesitate to get her attention. Emeraldas would've killed Tetsuro if it weren't for two things. First, Maetel (whom she also knows) is with him. Second, Tetsuro has Tochirou's hat and laser. She listens and then tells Tetsuro where the Time Castle will next appear: Trader's Fork, on the planet of Heavy Melder. 

        Some time after she leaves, she realizes something is happening on Heavy Melder, something that had to do with Tochirou. She arrives too late. Harlock tells her he's already dead. She leaves but later receives a message. It's from Tochirou, whose soul had been successfully integrated into the Arcadia. Learning that it was Tetsuro who had helped him, she realizes that she owes him a favor, and she proceeds to Andromeda, to repay the favor. She and Tetsuro will cross path a few more times. 

        Emeraldas is a very lonely soul, especially after the death of Tochirou. Her closest companion, like herself, is a wanderer. You see, the reason she and Maetel know each other...is because they're sisters. Emeraldas also has a daughter, Mayu, but she rarely sees her.

        Tochiro had been a close friend of Captain Harlock and a man dear to Emeraldas' heart. Among his many ingenious designs were four hand lasers, the most powerful ever made and the only ones known to kill machine men. He gave one to Harlock and one to Emeraldas. A third eventually ended up in the hands of Antares but was lost after his death. The fourth he kept for himself for a time. 

        Unfortunately, his traveling days were to be cut drastically short. He had caught a lethal disease, so he made one last visit to his mother on Titan. He gave her his hat and his laser. These two would eventually be given to Tetsuro. 

        He was on Heavy Melder, living the life of a hermit, his time running out and his greatest engineering feat almost complete, when Tetsuro arrived. He told Tetsuro when the Time Castle would appear, and in return, Tetsuro granted him his final request: to be integrated into his work...the Arcadia, the ship he was making for Captain Harlock. Tochirou's soul now resides within the Arcadia, giving the ship the unique distinction of being the only ship with a soul.

Qoute: "Don't...trust...Maetel."
 
 

        Antares was once a planetary pirate himself, and he still carries souvenirs from those raids: a number of unexploded bullets still in his body. Antares is a cautious sort, but he has several reasons to. First, there is the Paradise Law of Titan, which makes virtually anything legal. Second is the children, all the orphans of Titan that are now in his care. 

        He makes Tetsuro's acquaintance when Tetsuro rescues one of the orphans by shooting and killing the machine man by using Tochiro's laser (given to him by Tochiro's mother). Antares is surprised to see him holding the laser, but since Tetsuro saved the child's life, he shows Tetsuro around. He's still cautious of Tetsuro and Maetel until he uses an X-ray machine (considered crude by 30th century standards) to make sure they're human. Tetsuro's mention of Andromeda makes his blood boil until he hears the reason why. 

        Antares decides to take action and help Tetsuro, so he goes to Heavy Melder and hides in the Time Castle. When Tetsuro arrives, he reveals himself and provides cover using his own laser. However, Count Mecha outsmarts them, and Antares must make a final move to help Tetsuro. As he says a final warning to Tetsuro, he lets himself explode, shattering Count Mecha's protective shield.

Name: Claire [Clea]
Race: Glass Crystal Machine
Gender: Female
Hair: Clear
Eyes: Clear
Status: Waitress aboard the Galaxy Express
Likes: Tetsuro
Claire has been working aboard the train for a relatively short period, and she explains that her conversion ino a machine body was not really her choice, so she working to earn enough to but her human body back (a rarity when put in perspective). Tetsuro acts courteously (and a bit innocently) towards Claire, and she appreciates it. When she learns of Tetsuro's misson, she begins to worry. She knows that he'll probably get killed. She tries to plead with the conductor to avoid going to Trader's Fork so Tetsuro can be spared, but the conductor couldn't do it without risking his job. This only makes her more worried. 

        Her worry is a sign of friendship that eventually becomes love, a love that finally moves her to make the ultimate sacrifice to save Tetsuro from Queen Promethea's final attack. She shatters and leaves behind one crystalline tear.
