[ Just like she predicted, the glow comes back in full force once back in Ajax's hands. The matter of why the monster suddenly attacked them seems to be settled, it had to have been guarding this box specifically from him. But when one mystery is solved, ten more seem to crop out of the ground. That's how their life has been from the moment they obtained these strange marks, one mystery right after the other.

And now there are at least two dilemmas they are facing. Why is the box resonating with Ajax specifically and what is inside of it? Yoimiya watches him turn the cube in all directions, puzzled that it practically looks like a solid cube with no way of opening it. ]

I'm stumped too. Really strange that there isn't even a lock on it. Surely there should be some way to open so we can see what's inside...

[ An idea does cross her mind, but it involves Ajax tapping into his powers. After watching the poor guy trembling, there was no way she was about to ask him something that could potentially bring his trauma back in full force. His comfort is more important than some silly cube. ]

Hmm... I wish I had an idea but I'm totally lost. The only thing I can think to do is take the box with us and try to figure out the language inscribed on it.
