I recently came across Demon Sacred/Demon Seiten https://www.mangaupdates.com/series.html?id=1104. I just really want to know how it ends, it can be a summary or the raws I'm not picky. Honestly the best character to me was the regressed sister, I just want to know whether she ever grows up
Spoiler (mouse over to view)
i know she stops regressing
. Honestly even a simple yes or no would suffice if anyone could help me out.
