Editing Tenchi Muyo RPG (section)

===Background===
Characters suggested by the rulebook come in the following varieties:
* Central characters canon to the series, such as playing Ryo-Okhi or Katsuhito.
* Players are allowed to be the villains with DM approval. 
* Original characters that fit logically into the universe such as Tenchi's classmates, a fourth Choushin, or a space mercenary like Dr. Clay. 

Then it is suggested to decide on character background.
* House of Jurai characters begin with the Jurai Power ability, and have access to advanced technology although the character requires a background more extensive than most and their backstory will almost certainly factor into the plot in an ongoing series game. 
* Jurai-Earthling Mix characters most resemble the main cast of the series, such as Tenchi and Katsuhito making them the "Human" race of the game. Human mixes prior to Azusa and Funaho would have to have been kept secret or else the humans would have died normally (as an extreme version of the Elf/Human romance where most of human civilization is younger than the Elf analogue), since the revelation of Masaki's descendants being the people of Earth to the general galactic public came with them. 
* Galactic Citizen characters are of the other alien races in the setting. Only the Kuramitsu and Airai are given much background, with several aliens of different minor variations from humans and a few looking like bipedal animals appearing at various points in the series, usually as Galaxy Police. One arc of the comics involved the cast traveling the universe and meeting other races, most of which were unnamed and looked identical to normal humans (on a planet of darker skinned people, Ayeka asks if they are Kuramitsu with Mihoshi identifying their skin tone as being one shade lighter than hers in printing terms and goes on to say that means the're a totally different species). In another series, Tenchi and the cast also cross the universe and barring Juraians all people simply look and act like 1980's humans. Galactic Citizen characters have access to the more technological powers and have the suggested Galaxy Police, space pirate, or super-scientist archtypes. 
* Earthling characters are a non-factor in the OVA series, only being important in other Tenchi Muyo universes, but are nonetheless presented as an option. Unless you plan on the character being Sasami without any of the Tsunami moments however, giving a reason to have a giant robot is important (with "helped save a Galaxy Police officer and recruited into their ranks" being suggested by the rulebook). 
* Unique Entity characters are the final presented character type, representing fusion backgrounds (beware, [[Mary Sue]] potential is high) like Sasami being both a House of Jurai character in addition to being a Choushin, Washu being a super-scientist who is secretly a Choushin, Ryoko and Ryo-Ohki being Mass beings who are empowered by the energy of a Choushin, or Tenchi being Jurai-Earthling and also God and created the Choushin. So long story short, probably a Choushin related character. 

It is important to note that Mass Power characters are presented as an option, and it is shown by Dr. Clay that the Academy still has the research Washu had done on Mass while being able to create lifeforms without using her gems. Thus Mass characters are possible if somehow tied to the Academy, or a character from the Academy.
