Google turns up nothing but us, the Fandom site, and TV Tropes. And a few unrelated things with "Paladin" in the title. TV Tropes categorizes it as a Manhwa, btw, but their page hasn't changed since the fork. That's kind of pointing toward "bogus work" for me.
EDIT: No, wait. Found it. It's just called "Paladin" and Myanimelist.net has a page for it. It's also called Paladin: Inevitable Destiny, but no one but troping wikis calls it "Paladin: The Manga". Nominate for immediate rename.
