Unlike Light Novels/Mangas of the same genre like "Re:Monster" (slow, boring, repetitive) and "The New Gate", there's zero spoilers for the non-translated volumes of Tsuyokute! New Saga. Is it because the light novel is unpopular?
Totally zero spoilers found so far:

And the manga is going to take like 20+ years to complete the story with its current pace and monthly release and no English licensing is in sight for the Light Novel unlike the more famous Light Novel Overlord.
