Racepshi is a planetary class ship that has, so far, only been featured in the Tenchi Muyo! GXP novels.
Background
Racepshi is an entertainment vessel considered a treasure of the galaxy and retains complete neutrality, not being owned or controlled by any galactic power.
It is an ancient vessel, predating The Galactic Federation and maybe even the great prehistoric civilization. It is a smaller planetary scale ship, about the size of a small moon. It has a maximum capacity of 300 million that can accommodate on the ship itself, but it can also dock with so many ships that the capacity of it and docked ships can be 10 times that amount. It is secretly powered by a 3rd generation Juraian Royal Tree also named Racepshi which means that it could, if pressed, also exhibit a great offensive and defensive power. This also leaves it slightly vulnerable to Juraian ships of the 1st or 2nd generation, as well as Ryo-ohki and Fuku, because it would obey any commands from them and give any information it has access to if asked. It is unclear how long a royal tree has been at the center of the tree or who is considered the current "owner" and master of the tree. Other than one member of the operating family being an illegitimate daughter of a prince, no residents on the ship seem to have connections to Jurai. It may be that it is a unique masterless ship whose original master has long since passed. As the ship is ancient, it may also be an example of a tree/tree seed that predates the founding of Jurai, like Zinv and the original Knights of Renza.
It has the ability to light up brightly in order to make itself look like the tourist attraction it is but if a secretive group contracts it, it can also go dark. The inside common areas are always bright and festive, like Las Vegas combined with theme parks and every festival imaginable. Complete with beautiful hostesses and any service imaginable. It also contains priceless art of the galaxy spanning many ages.
Kiriko and others reacting to the dance of one of Makihi's daughters
It's main attraction though are the entertainers inside, headed by the dancing troupe known as The Mai Class. The general manager of Racepshi is Ekushito and he is married to Makihi, the head of their family of entertainers. Makihi is as much a title as a name and connotes that she is the top talent and manager of the rest. A Wakko is the lowest rank and cannot perform on stage. A Maiko, a dancing lady, can appear on stage in a supporting role. A Maihime, dancing princess, can be the lead in a performance. The entertainers aggressively pursue talent even to the point of mating talented dancers with others with possible talent. Makihi has ten children, but only two with her husband, the rest were picked in order to have a varied group of talented children. Her oldest child is actually Kyo Komachi, who decided to run away from home to be a pirate. Makihi encourages a very willing daughter of hers, a young Maiko, to seduce Seina to produce one of these talented children. Another daughter seduced a Juraian prince from the Tatsuki House (or possibly otherwise procured his sperm) in order to produce one of the leading Maihime.
Because of its neutrality it is also a meeting place for various factions, whether they be Juraian Royalty, Space Pirates, or Galaxy Police, where they are prohibited from conflict. When Hakuren and her group kidnap Seina before his marriage they escape to Racepshi, which then jumps to Renza Federation territory. A service they can provide for a hefty fee. Kiriko and her fellow brides barely sneak on in time to jump with them. Kiriko's group, as well as Hakuren's Renza group, then rent space on Racepshi and form their bases of operation there, with the express understanding that no confrontations happen on the ship. Doctor Clay, Kuis Panta, and other groups also gather there.
The Mai Class
Ekushito
The general manager of Reacepshi and husband of Makihi. Not technically a member of the Mai Class or an entertainer himself, but a persuasive negotiator and savvy businessman. The success of the ship rests largely on his shoulders.
Makihi
The Head of the Mai Class of entertainers. She has a captivating beauty and could obviously step into a dancing role at any time. Along with Ekushito, she makes the decisions of running the ship and how to continue its success. She has had 10 children but only two by her husband and the rest between two other men, as she chooses mates that will produce exemplary performers. Other than those listed below, she has three other children not mentioned in the novels. She also has her sights on Seina to produce children that have a similar probability bias as his in order to use them for the entertainment industry.
Kyo Komachi
Now a muscular pirate captain, she was a former member of the Mai Class who ran away to pursue her own life. Makihi has expressed that she is always welcome to return. Maito, who was too young to know his eldest sister when she lived with the family, immediately recognized her immense potential as a performer. Her name, as used, is probably not what she would have been known as. It could be speculated that her name would have followed the same naming conventions and been something like "Maikyo."
Maya
A daughter of Makihi who is pursuing a relationship with Seina Yamada, or at least trying to conceive a child with him. It has been confirmed she has a connection to him through her astral pattern being one that shares a connection to Mitsuki Sanada.
Maimu
An older daughter in the family. She is considered extremely talented and may be the most talented dancer out of any of them, able to instantly intuit how to perfectly perform any dance and captivate an audience in moments. However, she does not recognize her own talent and instead serves on the ship as a journalist. Her reports veer into the sensational and naturally have a focus on being entertaining.
Maihime
The highest ranking dancer performing on the ship (apart from her mother). She is an illegitimate daughter of a Juraian Prince and Makihi, (possibly the same prince who was the unwilling sperm donor that produced Palty Jurai). It is unknown if she was produced through artificial insemination, but it definitely involved the prince being seduced by Makihi.
Maiko
A young dancer in the family, described as the talaented dancer in an opening act before Maihime.
Wakko
A very young daughter in the family who is close to her brother, Maito. Only an apprentrice dancer at this point. "Wakko" is also represents a designation of her talents. Like all in the family, her name would be altered as she improves as a dancer.
Maito
The only mentioned son of Makihi, possibly her youngest child. He does not seem to be a performer himself but has an uncanny ability to ascertain the potential of a person as an entertainer and is instrumental in assigning tasks to arriving employees.
Others
Loretta Balta
A member of the Balta Pirate Guild (but not related to Ryoko Balta). She was working as a hostess on Racepshi when she met and subsequently ran away with and married Alan. As is the case with Alan, the two of them amassed a great debt and he ran away from her and his responsibilities. Pregnant with his child, she ended up living on Tabletop Island with her sister, Alea Balta, and contributed a small but memorable role in Paradise War, helping to capture Alan when he secretly arrived there in a lame-brained scheme to con the young pirates out of some money. Presumably, she'd always be welcome back to Racepshi if she wanted to return.
Marci Diplos
When Kiriko and the other girls arrived on Racepshi, Marci was assigned to the group as their liaison by Makihi. While she is associated with Racepshi, she is also a citizen of Renza and has a little more access with their federation.
Lazana
Lazana is a hostess who is contracted by Dr. Clay as a full-time assistant and companion while he is staying there. She is a capable person and Clay appreciates her calm demeanor. However, she takes her role as a full-service assistant seriously and tries to sleep with him and assist him in his night-time activities as well, even though he rebuffs all of her advances, insisting he only employs her as a companion to satisfy appearances on the ship, saying if he didn't have her there other hostesses would constantly be approaching him (as is their duty).
