Readers may imply from the title of Yaginuma's debut work that its story opens in 2015. The opening panels also indicate that the story occurs five years following the Lion accident, placing the mission's launch date in 2010. This is later confirmed in the first chapter of Twin Spica. Yaginuma, Kou[англ.].2015年の打ち上げ花火 // Twin Spica Volume:01(яп.). — Tokyo: Media Factory, 2002. — С. 125. — ISBN 978-4-8401-0428-9.
Mr. Lion does not reveal his real name. Instead, he uses the alias Lion (яп.ライオンRaion) when he meets Asumi. She attaches the honorific suffix «san» when calling his name, which is translated to «Mr. Lion» in the English version. Yaginuma, Kou[англ.].2015年の打ち上げ花火 // Twin Spica Volume:01(яп.). — Tokyo: Media Factory, 2002. — С. 131. — ISBN 978-4-8401-0428-9.
The supportive bond between the two is shown when Mr. Lion reassures Asumi that her father is not at fault in the Lion accident. In turn, she accompanies him as they watch the wedding of his former fiancée, who is also Asumi's elementary school teacher, from a distance. Yaginuma, Kou[англ.].Mission:09 // Twin Spica Volume:03(яп.). — Tokyo: Media Factory, 2002. — С. 19—25. — ISBN 978-4-8401-0468-5.
Shu refuses to follow in the footsteps of his father, a politician, and shaves his eyebrows before leaving to attend the space academy. His father is concerned about Shu's appearance in public.

Schaaf, Fred.Chapter 22: Spica // The Brightest Stars: Discovering the Universe Through the Sky's Most Brilliant Stars(англ.). — Hoboken, NJ: John Wiley & Sons, 2008. — P. 214—215. — ISBN 978-0-471-70410-2.. — «What's really fascinating is that the two big, bright, massive components of Spica are so close together. Their center-to-center separation averages just 0.12 AU—that's about 11 million miles, with the larger star having an average diameter of nearly 3½ million miles. [...] Could there be more stars in the Spica system? Apparently there is evidence from lunar occultations that there are three other, fainter components.».
