Shiba was already at his limit, but he was still enduring.
In fact, he had been at his limit for a while. Any other person would have given up long ago.
Even the audience was already worried by Shiba's state since he was covered with blood. However, most people were only aware of the injuries on Shiba's body. They didn't know that Shiba's soul was the reason he was at his limits.
Besides Lina, Eini had also guessed what was happening, but she couldn't do anything. Once the fusion started, there was no way to stop it.
Moreover, she couldn't get out of the barrier. There was no way the teachers would let any hole to appear on the barrier, which was being reinforced by them to ensure everyone's safety.
Eini felt powerless. Not even the teachers had the power to help Shiba. Not even Eini's sister, Lina, could help him. Even if she stopped blocking her own level, she wouldn't be able to change anything. All she could do was praying for Shiba's safety.
