That being said, let's get to Part 2 & see which were the best fights in the second half of Ring ni Kakero.
(WARNING! As I'll be covering exact fights, please keep in mind that I may venture into spoilers at times. I'll try to keep them as general as possible, but fair warning.)
Ryuji Takane vs. Napoleon Baroa
After being first mentioned at the end of the Champion Carnival, the World Tournament Chapter finally starts up, and the fights in this arc are almost all really damn good. While there are still some rather short fights (two of the fights against Team France are good examples of that), the rest all have something really cool to them. Ishimatsu taking on four members of Team Italy on his own, the crazy ability all of Team France have (which I'll get to in a bit), the scientifically concocted counter-strategies Team Germany uses to combat Golden Japan's superblows, & the sheer spectacle that is Team Greece are all excellently memorable moments, so choosing just one from this entire arc is really damn hard. If I can for a moment, I just want to give "honorable mentions" to Ryuji vs. Don Juliano (a very strong start for the arc), Ishimatsu vs. Tiffany (another showcase of Ishimatsu's tenacity), Shinatora vs. Himmler (if only for the Special Cross Counter), & Kenzaki vs. Theseus (the first time Kenzaki actually is pushed hard).
