is a series of books collecting short stories by Hiroyuki Morioka, set in the same universe and involving characters from his novels Crest of the Stars and Banner of the Stars, with many of them originally published in the S-F Magazine. The word Dansho refers to a passage from a written work, but there is currently no consensus on how the title should be translated. One story later included in the 2005 compilation Seikai no Dansho I, "Birth", was made into an anime OVA in 2000, four years after it was published in the S-F Magazine and five years before the consolidation of that story into the 2005 edition.
See main article: List of Seikai characters. Seikai no Danshō consists of short stories involving characters from the world of novels Crest of the Stars and Banner of the Stars.
A 2000 anime OVA adapted the first published Seikai no Danshō story, "Birth", that was included 5 years later in the 2005 book Seikai no Dansho I.

It was also included in Crest of The Stars and Banner of the Stars Blu-ray collection, released in Japan on December 25, 2019.
"Contact", "Original Sin", "Annexation" and "Childhood Friend" adaptations were broadcast in 2006 by FM Osaka internet radio. "Original Sin" was the last work of the Seikai series starring Hirotaka Suzuoki, who died the same year.
