Kii launched a sequel manga titled Harukaze no Etranger (L’étranger du zéphyr or The Stranger of the Spring Breeze) on On Blue in July 2014.
Shochiku is streaming a teaser for the anime, which features a visual that Kii drew for the anime.
Three years later, Mio returns to face his feelings. Umibe no Étranger is Kii’s debut work as a manga creator, and it ran in Shodensha’s On Blue magazine in 2013.
The project is Blue Lynx’s third project, after the Twittering Birds Never Fly and Given theatrical anime films.
