[1] Shibano (under the pseudonym "Kozumi Rei" (小隅黎)) chaired the Science Fiction Writing Club (科学創作クラブ, Kagaku Sōsaku Kurabu) after participating in the Japan Flying Saucer Research Association (日本空飛ぶ円盤研究会, Nihon Soratobu Enban Kenkyūkai).

The club changed its name to Uchūjin before the first issue, and focused on science fiction writing, translation, critique, and related topics.

Since the first issue, many of its contributors went on to become well-known speculative fiction writers, including Sakyō Komatsu, Yasutaka Tsutsui, Ryū Mitsuse, Shinji Kajio, Akira Hori, Kōji Tanaka, Yoshinori Shimizu, Baku Yumemakura, and Masaki Yamada.

They also released a self-parody fanzine titled Space Deer (宇宙鹿, Uchū Shishi) in the same year.

The final issue contained memorial tributes to Shibano, including an interview with his widow.
