Plan

As we readied ourselves, the women began to open the door ever so slowly while hiding behind it. Even if the Grimm Monsters attacked, they would have to attack the door, and these doors are strong enough to bear the attacks of Grandmaster, so bearing the attacks of the Masters would not be any problem for it.

The door began to open slowly, and soon, it had opened enough that one person could walk through it, but the Grimm attack we had been expecting from it had not come.

Instead, we saw a red halo, and when we had craned our neck inside, we saw the glow is coming from the huge steles. There are tens of them in a huge hall that stretches about a mile.

All these steles are letting out a deep crimson light which seemed to create a suppression that I could not move my soul sense in it, and this scarlet glow has covered the whole hall in light, I could not any other color than the scarlet.
