Mines is the Chunin Exams arc
I’ll go outside the box and say Battle City in
Yu-Gi-Oh!
Mine is the Duelist kingdom in Yu-Gi-Oh
I'm a sucker for the dark tournament in Yu Yu Hakusho
Chunin Exam was amazing BUT MHA'S UA SPORTS FESTIVAL ARC IS THE BEST for me
Chunin Exams all the way
Most of the Chihayafuru tournaments...
What do you think?
