Sparda hated seeing his family fight.
He felt weaker than ever, watching his two twin sons clash and not being able to intervene like a father should.
He continued to resonate great amounts of power in an attempt to catch their attention, but they were too consumed by their battle rage to notice him.
Sparda ignored the other Devil Arms cheering his sons on and continued to emit waves of demonic energy. Soon, he felt the side of him hanging on the wall rattle, loosening his restraints.
He may have been stuck as a Devil Arm, but he could still move to an extent.
Sparda had awoken many years ago, before the uniting of the Perfect Amulet and his true power being returned to him.
It was when that man, Arkham, tried to use his power to rule the human world like Mundus before him, Sid after him and even Arius after that.
He had been an integral part of the clash between Dante and Vergil, resulting in his older son's fall into the underworld and his corruption at the hands of Mundus.
Even then he resisted their fighting intentions, refusing to release his full power in Vergil's presence.
Sparda had little of his memories, but he was still the same Dark Knight.
The last thing he remembered was sealing his power and a backup of himself in his sword, and his awakening by Arkham.
Now, a great many things had passed since his awakening, including the second defeat of Mundus and his full awakening.
Along with the reunion of his twin sons, who were now trying to kill each other once more.
Sparda prayed quietly to the spirit of Eva, hoping that his sons would not kill each other. He still had yet to truly meet his grandson, Nero.
Sparda gave another brutal push, releasing even more power than previously. His display on the wall shook, and the nails creaked.
That was when Dante collapsed, leaving Vergil headfirst in the floorboards and out cold.
Sparda sent one last wave of strength outward, ripping his display nails out of the wall and sending him tumbling onto the floor.
He continued to shake on the floor, producing a constant rattling sound.
He didn't have the power to move more than he already did, leaving him helpless on the floor.
Sparda sighed, his power dissipating. He was stuck on the floor, forced to wait.
