Manga creator Chika Katō revealed on Twitter on Friday that the Shōkoku no Altair Gaiden: Tōkoku no Subaru (Subaru of the Island Nation) spinoff manga will end in its seventh volume.
The manga is a spinoff of Kotono Katō’s Altair: A Record of Battles (Shōkoku no Altair) manga.
The magazine serialized Shiina Soga’s Shōkoku no Altair-san (Altair of the Tiny Nation) spinoff manga from 2012 to 2013.
Kotono Katō launched the main Altair: A Record of Battles manga in Monthly Shonen Sirius in 2007, and the 21st compiled book volume shipped last September.
