Do you realize that pretty much any other character in the Nasuverse has lines (can die) with the exception of Arcueid under the Moon and ORT? Because to be fair we don't even know if the other Types also lack a concept of death. Also you seem to be forgetting that Arcueid never fights on the day, and even if she were forced to fight on the day against a powerful enemy, she'll probably just use her power to create a lunar eclipse by accelerating the Earth's rotation, which should be easy for her, considering she managed to turn the moon red in MB.

Also Shiki only managed to kill her because Arcueid doesn't attack humans, and she was shocked that a normal human would have dared to attack her. Therefore she hesitated. However, this will never happen a second time.

And Arcueid gets power from the Moon because she is a cooproduction of both the Earth and the Moon. So she is only a perfect life form under the Moon.
