Person: Morioka Hiroyuki

Morioka Hiroyuki was born on March 2, 1962 in Hyogo Prefecture, Japan. He is a sci-fi novelist.

In 1992, his first novel Yume no Kki ga Tsugeta nara ("If Only the Dream Trees Could Touch") appeared in Hayakawa Shobo (Tokyo)'s S-F Magazine. His short story "Spice" won the Hayakawa Award in 1993.

In 1996, he published his first long novel in three volumes, Seikai no Monshou (Seikai no Monshou/Crest of the Stars). In the next year 1997 Seikai no Monsho was awarded with Seiun Award at the Japan SF Convention. He released its sequel Seikai no Senki (Banner of the Stars), where he said that Seikai no Monsho was actually an overture to Seikai no Senki. Morioka had already suggested in Seikai no Monshou 2 that the entire series should narrate the life of Princess Lamhirh (aka Lafiel), from her birth to her eventual ascension to the imperial throne. Three volumes of Seikai no Senki are now available and Morioka named them "Diahoc Trilogy" but the series itself has not yet finished. An English translation of "Seikai no Monshou/Crest of the Stars" is being published, the first volume of which was released in fall 2006.

Aside from the Seikai series, he published another Senki in 4 volumes, based on Japanese mythology.

His characteristics as a writer include a deep interest for linguistics (specially for conlangs), artificial intelligence, bitter humor, and well-designed world settings.
