You, Kyojuro Rengoku and Tengen Uzui were fighting an Upper Rank, who has trapped you in a box.

Tengen was thrown in first, then you, then Kyojuro.

And then you were shut in.

So currently, you're trapped in between the two of them, laying on Tengen with Kyojuro laying on top of you.

There were small peepholes, so you could breathe, bit you were utterly trapped.
