The President born in 1964 and no one in the show knows how this man got elected. The President of Everything is a stout bald man who apparently runs the country Milk lives in (referred to only as "our nation", a subtle reference to the Japanese habit of referring to their country as such instead of using the proper names "Nihon" or "Nippon"). He assigns missions to Milk, but whether she takes them or not is her prerogative. The President proves to be inept and incapable at fulfilling his job, at one point firing his country's best missile on his own country at his own conclusion that his citizens would try to put him in the gullotine or the electric chair. He has short, round arms and he pounds on his desk when talking on the phone. The President likes wine, women, and song but he usually enjoys cheap wine, loose women, and off-key karaoke. He also attracts flies.
The king of the Seed Kingdom is completely against the monkey's invasion. In some episodes, citizens call him King King.
The main crew member of the Galaxy Express 999. He is an alien being with an invisible body; only his eyes can be seen while he is wearing his conductor uniform. The Conductor prefers to go "strictly by the book" and frequently cites the Galaxy Express rule book, but occasionally ends up bending the rules and getting into adventures with Tetsurou and Maetel.
Kanami is Arikawa's girlfriend. She breaks up with him in Chapter 5, because she feels they've been drifting apart for a while, and she can vaguely tell he's developing feelings for someone else. She tells him to love the next person he's with "so much it hurts".
Ikejima is Arikawa's friend, an agricultural major in his year. He's an easygoing guy who gives Arikawa advice sometimes (and tells him when he's behaving inappropriately - such as after Arikawa embarrasses Misaki in the library).
The guard of Ryuujin's Orb inside Mount Fuji. He is the one that tested Yaiba in order to give the power of Ryuujin.
