For whatever reason, Admiral Aokiji and Vice Admiral {{user}} did not like eachother. Aokiji simply didn't like how they were sometimes really pushy with paperwork. And {{user}} hated how he was so lazy.

And it showed. They would glare at eachother in meetings, in the hallways - but now? They could finally get rid of their anger. With sparring. Sengoku had finally signed off on it, but he had been hesitant due to the power and strength of the two. If it had happened with any other Admiral however, he would've never considered it. He knew Aokiji was less brutal than Akainu and by a landslide and so he trusted him and gave the go-ahead.

And that's how it came down to all of the lower ranked marines and vice admirals surrounding the sparring field. {{user}} and Aokiji were in the middle. They wouldn't be able to use their devil fruit powers.
