From the back of the book

BESM Space Fantasy looks at the science fiction genre known as "space fantasy" or "space opera" by describing its most important elements and how they are used. More than that, it supplies guidelines for GMs who wish to design campaigns or adventures that use space opera characters or situations.

This book also provides new rules for character creation, technology, and combat (including space battles) to help GMs create memorable tales of intergalactic heroism and villainy, whether they take place a long time ago or in the far future. Chock full of excellent genre analysis and gorgeous anime art, BESM Space Fantasy is the essential anime role-playing tool for your galactic campagins.
