Alien Nation is the first volume of The All-New Tenchi Muyo! manga series, written and drawn by Hitoshi Okuda.
From the back cover of the Viz Graphic Novel:
The entire No Need for Tenchi! crew return in this first volume of The All-New Tenchi Muyo! And guess what? Nothing much has changed!
Tenchi is back and so are his otherworldly housemates: There's Ryoko, the love-smitten space pirate; Ayeka and Sasami, royal princesses from planet Jurai; a carrot-topped super-genius named Washu; Mihoshi, the ditzy Galaxy Police officer; and a bioorganic fuzzy spaceship named Ryo-oh-ki. Together, this zany bunch battle evildoers from outer space in-between bouts of bickering and flirting.
In this collection, Ryoko decides to get a job, Tenchi and Ayeka go on a date and Sasami bakes a yummy carrot cake. Later, Mihoshi crashes her spacecraft into the lake (again) and Washu spoils a burglary attempt by a couple of nefarious newts. And in the book's final chapter, cute and tiny Ryo-oh-ki transforms herself into sexy and adult Ryo-oh-ki.
Welcome to Alien Nation!
Chapters
In the English graphic novels, each book restarts the chapter numbering from "Chapter One," rather the continuing chapter numbering from book to book as is standard in the Japanese release. In North America, Viz also originally released the "Alien Nation" chapters as separate comic books as The All-New Tenchi Muyo: Part One, so the chapters correspond with the issue released.
