Ren who was watching the duel from his own special spot was quite amused by the way the two were fighting. Several decades ago he might have thought those two were a little powerful, but now after seeing Ancient Ones, Dragons, and the ORIGIN himself, this kind of fight looks like children play fighting.
Still, it was good enough if they were fighting against New Gods. Also seeing them fighting like that made Ren itchy as he too wanted to fight.
"I can already guess what you're thinking. You're itching for a fight, if you want I can always accompany you."
"Alright then, after their fight let's you and I play for a bit."

Nero and Julius were near their limits and were about ready to unleash their final blow. Julius checked his items hidden in his sub-space and saw that he had already used almost all the items he prepared for this fight.
