Ren opened his eyes. His consciousness gradually gathered back. He found himself still inside the cell. Wasn't Sekidora supposed to have destroyed this cell?
He got up and sat while rubbing his face.
"What happened? Weren't you supposed to destroy this room?" Ren asked Sekidora.
At that moment, Sekidora and Yuzuru had already been freed from the chains that bound them. The same went for the handcuffs that restrained Ren's hands. It seemed that Sekidora had broken the chains and handcuffs that bound them while he was unconscious.
"It seems my calculations were wrong; this room is stronger than I thought. I need to use my strongest explosion to destroy it," Sekidora answered Ren's question.
If that were the case, then Sekidora was probably recovering right now, so he could use his strongest explosion.
"Will it take long?"
"I'll be able to use my strongest explosion in a moment."
