Well since he traveled here magically I guess that makes sense. Either that or Diva is putting people into other dimensions again. ^^;;

Also the plaza clock is once again stuck at the time that Battle City began.

It’s the same place where they Dueled Paradox in Bonds Beyond Time, and other places! This is a very significant clock. 

I give you bonus points for bringing up Diva! XD

Oh that’s right, they did duel him there too! They really do milk this plaza and clock for all they’re worth. XD

There’s a reason for that! In the DM manga, this is where all the main duelists’ arcs begin to resolve. Atem begins the concentrated battle to find the God Cards and thus his name; Kaiba, while not present here, runs this tournament and uses it to come to terms with his trauma; Jyonouchi says he wants to become a true duelist, and begins that journey here (culminating between Battle City and Memory World—if you pay close attention, he beats Atem off-page in their post-BC duel); and Yuugi, for the first time, must start facing the inevitability that Atem will learn his name and become his own person again.

Battle City, this clock and time specifically, take us “back to where it all began.”
