Assassin Battler is seen looking at his computer in the Blue Team base, switching tabs while playing a battle royale game. Where he got the computer from is unknown…

Assassin Battler: "Hoyaaa! NOOOO!!! YOU SHUT UP WHEN I'M TALKING TO YOU!!"

Sounds like he's getting mad at someone. He then proceeds to rage and smash his table while failing to speak Japanese, or more accurately intelligible gibberish. Many battlers around him didn't question it, presumably because they were used to it.
