“時空（とき）の旅人” occupies position 10, listed track number 10 in the 16-track WPCL-12756 edition of Mariya Takeuchi’s “REQUEST”. This CD release is dated 2017-11-22; the album’s original year is 1987. The title and position together identify a particular place in this edition’s program.
In this sequence, it follows “夢の続き” (09) and precedes “テコのテーマ（Single Version）” (11). The source places it within the original-album program reproduced on this expanded edition, rather than in the appended bonus section.
The related “REQUEST” essay supplies the album context. This entry adds the edition-specific title and placement without assigning writing or recording credits merely from a matching name. A shared title, release date or remaster label does not by itself establish audio identity across editions.
