Starship Girl Yamamoto Yohko

The four main characters are high school girls.

Yohko Yamamoto (山本 洋子, Yamamoto Yōko)

(Voiced by: Minami Takayama):

Yohko is an active, sporty but cocky girl. She is a hardcore gamer, preferring space fight simulations, and is occasionally bribed using games. She is usually seen eating Pocky. In the first episode of the TV series, it was revealed that she had lost her memories. However, by the end of the same episode, she regains her memory while participating in a space battle. She was the first pilot to be recruited by Lawson, happening to be the first person he met after travelling to 1999 AD. She considers Rouge of NESS's Red Snappers to be her rival, both in space battles and in love—they both are attracted to NESS's Fluger. She pilots the Super Strike TA-29, armed with the all-powerful Everblack Cannon. Due to her obsession with games, she is required to put in a 100-yen coin into an arcade-like coin slot to start her starship.

Momiji Kagariya (松明屋 紅葉, Kagariya Momiji)

(Voiced by: Satsuki Yukino (TV)/Shiho Niiyama (OVA)):

Initially a mysterious figure, Momiji is the second of TERRA's pilots. She replaced Yohko while waiting for Yohko to regain her memories. A long-haired, somewhat masculine girl, she speaks in the kansai dialect. She's strong willed and a team player. She works part-time at a mini-market. She has a crush on Lawson, and for a short period believed that Yohko was attracted to him. However, Yohko herself denied this, and later revealed indirectly that she was attracted to Fluger. She is the pilot of the Super Storm TA-23, armed with MRLs and Laser Arrays.

Ayano Elizabeth Hakuhouin (白鳳院 綾乃 エリザベス, Hakuhōin Ayano Elizabeth)

(Voiced by: Yuko Miyamura):

A kind-hearted girl; also the third pilot. As Yohko's best friend, Yohko trusts her and believes that Ayano's abilities would outmatch her own in the right circumstances. She's generally quiet and she truly cares and admires Yohko since childhood. She lives with her grandfather, the Master of the Hakuhouin-Ryū Judo Family. Thus, Ayano seems to be his successor, and can be seen in several episodes practicing judo with her grandfather. She seems to lack confidence, but enjoys starship battles. In later episodes, she strives to be independent of Yohko, making her go against Yohko in a starship battle. Pilots the Super Struggle TA-27, which mainly fires grapple hooks to latch onto an opponent and throw them—an extension of her judo abilities.

Madoka Midou (御堂 まどか, Midō Madoka)

(Voiced by: Megumi Hayashibara):

She is the main comic relief of the series. Her character is easily recognized due to her large, reflective forehead, which is often the object Yohko's insults. She considers herself Yohko's rival, and strives to beat Yohko in all aspects, such as in sports, studies, and even gaming. Her efforts can be observed when she aspires to become a starship pilot, and her diligence in overcoming vertigo. However, she is the least competent of the pilots. She is very poised but kind of spoiled and happy-go-lucky. She also believes in making an impact, as shown by her choice of dressing as a zombie for a costume party. She also comes off as a slight anime otaku. She also falls head over heels for Yamamoto Yohsuke when he appears in the series. Pilots the Super Sprint TA-25. Its specialty is its powerful Vapour Shield. Reflecting her impatient personality, she uses the shield as a battering ram rather than as a defensive device.

Ayano's Grandfather

Although not involved directly in starship battles, he seems to understand that the girls have a more important role than what they seem to be and supports them, especially Ayano. Extremely intuitive about his surroundings, he is also somewhat eccentric. Although he is the master of the Hakuhouin-Ryū martial arts style, he is relatively weaker than Ayano. Later, he accepts Yamamoto Yohsuke as his apprentice, and they begin training in the wild.

School Council President

A minor character, he is the successor to an udon shop. When Lawson visits the 20th century, Momiji goes to him to learn how to make udon (after having doubts about Yohko). He is the first person in 1999 AD to realize that Yohsuke was female when he saw the shape of Yohsuke's body in the rain. Although he has photographic evidence, he tries to force himself to believe that it was simply a delusion by making udon and then eating it.

Admiral Zena Leon (Voiced by: Masako Katsuki)

The highest-ranking officer on board the Estanatreich. She was once a TERRA pilot, but was promoted to command. She once fought in a battle with Fluger known as Little Big Horn. She pilots the Super Twister TA-21 in the Zenga tournament, partnered with Fluger. The TA-21 is also equipped with an Everblack Cannon. It is indicated that they had had a relationship. She was in charge of the TERRA and NESS joint-investigative team researching the Old Timer's Legacy, along with Sara.

Curtis Lawson (Voiced by: Yasunori Matsumoto)

A genius engineer. He worked on the time travel machine that is used as the gateway between 1999 AD and 2999 AD. He also designed the TA-series of ships which are used by the girls. It is later revealed that the reason he chose to go back 1000 years in time back to 1999 AD was because he discovered the Yamamoto Yohko novels, and was intrigued by them. Following their premise, he created a gateway. When the gateway was completed, the first person he met was Yamamoto Yohko. He was surprised as he had thought of Yamamoto Yohko as only a fictional character in the novels.

General Fluger von Meo-Toroll

The commander of Meo's 2nd Fleet, in charge of the Red Snappers—the aces of NESS. He is often represented riding on a white horse, which gives him the image of a knight. He is a capable leader, admired by Rouge and Yohko. Like Admiral Leon, he was also a former starship pilot who had been elevated in rank. In the Zenga tournament, he pairs up Admiral Leon. They name their team after one of their most memorable battles—Little Bighorn. Pilots the Torom 3 Skipjack. As a pilot, his skills are impressive, as shown in his ability to defeat Momiji in the Zenga tournament by directly attacking her control area, thus defeating her with minimal damage to her ship.

Rouge (Voiced by: Sakiko Tamagawa)

The oldest sister, and leader of the Red Snappers. Blonde-haired, she is proud and strong. She and Yohko are rivals, both in starship battles and in love. Rouge admires Fluger, and seems to owe him a debt of gratitude for helping her family. Although she almost beat Yohko in their first space battle, she was stopped once Fluger realised she had removed her automatic teleportation module—the device that would teleport her out should her starship be destroyed. Yohko defeats Rouge in their next battle. While the Red Snappers were stranded on the 'Boiled Egg', Rouge is trapped and finds out that Yohko comes from the past. She challenges Yohko to a duel, hoping to keep Yohko in the past. However, due to an emergency, the fight is inconclusive. In the end, they race each other on foot, with Yohko winning. She pilots the Red Snapper Superior, which is equipped with the Ultimate Impulse Cannon, a weapon that is comparable to Yohko's Everblack Cannon. Like the other Red Snappers, her name is related to "red": in this case, rouge is the French word for "red".

Rote (Voiced by: Mika Kanai)

The second sister, Rote is red-haired and often seen laughing. Her laughing usually annoys Madoka, and they seem to consider each other as rivals. She pilots the Red Snapper Spirits. Her name is the German word for "red".

Lubrum (Voiced by: Yukana Nogami)

The third sister, and the most masculine, grey-haired Lubrum wears a spiked choker. Her ship is the Red Snapper Premier. The closest comparison to her would be Kagariya Momiji, however they do not come off as rivals. Rubrum, an alternate romanization of her name, is a form of rubor, Latin for "blush".

Erytron (Voiced by: Masami Suzuki)

The youngest sister, she is very apologetic. In the first fight, she uses her ship's shield as a battering ram, not unlike Madoka's usage of shields. However, she is seen to be apologizing throughout the fight. She pilots the Red Snapper Extra. She is comparable to Ayano, however Ayano seems to be more proactive than Erytron. Like the other Red Snappers, her name is an allusion to the color red. Her name is probably a Japanization of erythron, an element of the blood-forming system involved in the production of red blood cells.

Lyle

Leader of one of the first teams the girls face as a four-person group. A nice man, he believes in sportsmanship and guts to be the path to victory. He and his group seem to be military otakus, doing physical training before battle—though it is difficult to see a direct correlation between physical ability with starship control.

Ghost Captain (Borei Kancyo)

A figure wearing a skull mask. Replaces Madoka in the Zenga tournament, and is paired up with Ayano. The Ghost Captain's ship is the Keroberos G-59 Gaigotsumaru, looking like a seafaring sailing ship with a large Jolly Roger on the prow giving it a resemblance to Captain Herlock's Arcadia.

Yohsuke Yamamoto (山本 洋介, Yamamoto Yōsuke)

A clone of Yohko, created by Zenga using the Old Timer's Inheritance. Although biologically a girl, Zenga seems to have brought Yohsuke up to be a man. She first appears in the series as a young child, to observe Yohko's life. Later Yohsuke appears in the series in the guise of a man, and joins Madoka's class on the last day of school. He also has an obsession for fish-paste sausages, possibly a Freudian expression of her desire for a phallus (or maybe just a masculine counterpart to Yohko's ever-present Pocky). Due to their similar, strong personalities, Yohko and Yohsuke do not get along with each other. Madoka has a crush on him, not realizing Yohsuke is a clone of Yohko. An accident later turns Yohsuke into a man biologically. He then becomes an apprentice to Ayano's grandfather. Yohsuke pilots a copy of the TA-29. However, Yohsuke's ship uses a 500-yen coin instead of the 100-yen coins Yohko uses in her TA-29.

Ginga Bancyo (lit. Galaxy Boss)

A man whose face is wrapped in bandages. He is in charge of the Zenga tournament. He reveals himself to be Yamamoto Yohsuke to the girls before his fight with Yohko.

Zenga von Meli-Su-Han

The old man who hosts the Zenga Tournament. He aims to rule the universe by controlling of all the Old Timer's Inheritances, and uses the Zenga Tournament as a means to this end. Although he 'created' Yohsuke as a tool, he ends up finding Yohsuke hard to deal with.

Tenzer von Meli-Su-Hun

He is Yohko's first enemy in the TV series. After his loss, he is constantly seen requesting Zenga for a starship so he could face Yohko again. Although he is related to Zenga, Zenga does not seem to think much of him. Tenzer has a crush on Ayano, and believes that he will win her heart by showing her his strength in starship battles. However, he loses to her in the Zenga tournament.

Sara Dread

A biological engineering researcher who was intimate with Lawson. After having her confession rejected by Lawson, she used the TA-21 to enter the heart of the Old Timer's Legacy she was researching. Entering an eternal sleep, she created the planet Sakura Taurus. Due to damage done to Sakura Taurus, Sara regains some consciousness. An extension of her hatred towards Lawson manifests itself and begins attacking the Estanatreich. Later, the girls and Lawson enter into the heart of Sakura Taurus into the Old Timer's Legacy to awaken her. Zenga used her feelings of hatred against Lawson to bring her to his side.
