Tercüme - İngilizce-Japonca - Angels don't enter here.

Since, it is part of a song. I tried to be more poetic than translating it word by word.
"do not enter" would be 入らない or 入って来ない, but I used "do not descend" 降りてこない. Considering they are angels, they rather descend from the heaven to enter this world.
