Kirumi Tojo's Palace | The Ultimate Maid's Failures

By now everyone may be used to find themselves in bizarre locations, between going into palaces and visiting Nekyia. It might not come as a surprise that it has happened again.
What might come as a surprise, though...is how empty this place is.
All around you there's nothing more than a large, gray, featureless expanse. In the distance there seem to be bars, curving upwards to gather so, so high above you, possibly hundreds of miles above, so high it’s hard to distinguish.
It’s a cage. So unfathomably large. You could escape, were you to get to the edges of the cage, but...it would take forever. No matter how you look at it, you're trapped. The atmosphere is so...hopeless. Devoid of anything even remotely positive.
Not that you want to hang around for long, do you? After all, this is someone's palace. Not a place to stick around at. What to do, though?
It’s all so...empty. Silent. Featureless. A flat expanse of hard gray tiles.
Gather together, everyone. Gather and choose a direction. North, East, West, South. All directions look completely identical, but could it affect your time in this place, somehow? Probably not. But all treks start with the first step. Perhaps, if you get moving, you'll progress?

The entire painting vanishes. Instead, there's a dark gray text on white]
'Monokuma has been leaving Flashback Lights for us to find. They were hidden, yet I feel Monokuma intended us to find them, as if that were a game.
We all gathered together and turned the device on. When we did, we remember things.
We remembered the Ultimate Hunt. We remembered people wanted us dead. We remembered we threw our talents away to hide from them.
Why is Monokuma giving us memories we seem to have lost?'
