According to Denshi Jisho, 宣 means "proclaim/announce" and 死 means "death/die", but can't find a meaning for both of them as a word.

I don't read spoilers, so you'll have to wait for TUSF to see this thread.

For your last question:

"Don't you think going all the way up to the fiftieth floor is boring?—Eugeo-san, we were born and raised here, in this cathedral. We were made by the brothers and sisters in the tower under orders from Administrator-sama, you know. For her «resurrection» sacred art experiments that can recover Life that had been completely lost."
