Thanks you , translation team , for your works . Maybe chapter 15 's raw will be released a few months later .
There was a 3 months gap between chapter 13 and 14 : http://www.comic-valkyrie.com/modules/web_valkyrie/teisou/ .
I guess this series is just a side project / hobby project of Amahara . Im afraid it will get axed soon .
Amahara 's main project is Interspecies Reviewers , it already has 2 volumes , and even a Light Novel adaption(?) : https://www.amazon.co.jp/%E7%95%B0%E7%A8%AE%E6%97%8F%E3%83%AC%E3%83%93%E3%83%A5%E3%82%A2%E3%83%BC%E3%82%BA-%E3%81%88%E3%81%8F%E3%81%99%E3%81%9F%E3%81%97%E3%83%BC%E3%83%BB%E3%81%A7%E3%81%84%E3%81%9A-%E8%91%89%E5%8E%9F%E9%89%84-ebook/dp/B07L4C6RZ3/
