Mundus was the enemy of the Sparda family, but not Roy's. Roy had not even seen Mundus before, so it was impossible for him to do his utmost to deal with Mundus.
However, it was an indisputable fact that Mundus had taken away the Ouroboros Mark that the Gate of the Abyss had given Roy. Therefore, even if he did not do his best, he still had to take action.
The head of the statue fell, and the torso of the statue naturally did not last long. Tens of thousands of tons of stone fell from the sky, causing intense tremors on the ground. After seeing the statue fall, the demons watching in the distance cried out and fled in all directions.
But no one present thought that Mundus had lost nor that it was over.
Fat Tiger, Cerberus, Cassandra, and Sareth crouched far away. In this battle, they did not have much room to take action, so it was better to watch.
