For some reason 'Nidome no Jinsei wo Isekai de' ch 164 was posted on the page for 'The Spearmaster and the Black Cat' by mistake
releases for group INT were auto-added by bot. it reads the category/tag to determine which series the post/chapter is for, and for this case, @ShasuX mistagged the post as Spearmaster instead of Nidoume.
