Their passion, regardless what you think of the teams' current performance is still contagious even if you don't understand the language. Sure they're critical of the performance, but they also want the players and org to do well.
I support DFM since the Crazy Raccoon takeover- and I'm a lowkey CR fan since they started. Their vibes are iconic, their personalities are fun- there's a reason why they are one of the biggest entertainment organizations in Japan. And since CR looked like they actually want to improve (despite their attempted self-sabotage before), you can't help but wanting them to do so. They might bear DFM's name, but everyone who follows them now knows that in heart, they're Crazy Raccoon.
