Capítulo 320: 5.13.4 The Bone of Judgement.

"We have to open it… save him at least." Henry said, striking the door, but the door didn't budge at all.

Something was holding it from the other side, and it was definitely not magic. 

So what was it? Sheva had no answer, neither did Henry. Both of them wished to move past it. But then the question was, what can they even do after entering that place beside dying under the attack of those bizarre monsters?

And as they were having such thoughts, Sheva's mind fell back to the potion bottle that had fallen out of Crow's bag. A drug that Jara once drank, which ruined his life forever. It was not in her hands and she wondered if she should give it a try as well. 

'I came here to die anyway.' She knew the dangers and how she had thought that Jara died that day. And if she didn't think wrong, something the same might happen to her. No, in her case, she doesn't even know if she possesses a bloodline to begin with.
