Wow, you seriously missed the point. Again.
He's about to have a final showdown with Garou... something big is about to happen...
If you're reading OPM and are seeing a FINAL BATTLE ABOUT TO HAPPEN and not expecting something big, I don't really know what you're thinking.
I didn't say he was pissed due to Garou. I said he was pissed, and he's about to fight Garou. Like I said, reading comprehension.
Hell, i'm not even saying I would disagree with a 5-B upgrade. I'm just advocating for some patience before we do anything, as almost nothing happened this chapter. Something big is about to happen. And i'm not even saying it'll just be 5-B, we have no idea what's about to happen, but it's going to be big.
