Almost certainly "Cross", since this is how Japanese anglicize the word for terms like "cross stich", and it fits for a cross between a demon and a human.
I honestly have no clue. The name in Japanese is "クーロ=ス" which when I put into a translator it comes with "Kuro=S" or "Kuro=Su" I'm guessing the = sign comes from the equal sign in the name. And If I search the name in google randomly, that also says Kuro.
"I want a family." And there it is folks, the villain is now "relatable". And of course, since the pacing has been completely schizophrenic so far, we're going straight into a beach episode. My soul hurts. Thankfully there's only 15 chapters left. Hang in there Tripolar, you're not suffering alone.
so what can the godess shield do and why would kuro=so need it? If he just want this one gift then he would need the godess staff? No explanation from the pope...
