@asianskill bro how is that even an argument, this situation is completely different. Yuu
wasnt even jumped he literally knew he was going to be fighting so its his fault for not keeping his head screwed on straight
Think of it like this: If things like environmental factors don't matter, why do professional sports leagues have teams play at home and away? Sports matches and, obviously, fights have to take place SOMEWHERE — you just don't understand how significant the psychological effect the environment you do something in might have on you
If you're fighting in an unfamiliar to yourself environment, filled with faces you don't recognize, while also suddenly having the obligation to spar thrust on you — of course you'd be taken by surprise
Yuu went to the dojo because he was expecting Shougo to reconcile with him, not have a sudden fight with the top student there
It goes without saying, but it seems Osada is the strongest one at Hakusenkai
You mentioned that it doesn't make sense for Yuu to be "caught off-guard" in a fight, since he supposedly always fights in the streets like you said — you're forgetting the fact that people change their mindset depending on where they are
At school, you're in the mindset of "studying" or "learning" — not getting into gang shootouts or whatever
Similarly, at work, you're thinking of working and making money
At home, you're thinking of resting or relaxing
It's only in the streets where it's more appropriate to have that "danger-wary" mentality you're talking about
Yuu is always ready for a fight out on the streets, but he wasn't expecting to suddenly get bloodied up in a supposedly honorable place like a karate dojo
