WOW! That's a 10 right there!
Spoiler for celebrate good times with KOOL and the gang...:
First of all - SATOSHI'S ALIVE! *dances*
Now that that's out of the way, I didn't think anything other than watching KOOL go Incredible Hulk could have made that fight any better - well, OK, maybe better animation, longer fight, and using more powerful BGM like the remix of You that Rias posted woulda helped, but still, watching Akasaka beat ass followed by gun-toting Shion and Kasai made my freaking day!
In fact, I need to watch the damn fight scene again! :-D
On a side note, looks like Rena's out of the picture for pairing with K1 as far as anime's concerned. Oh well, she could always take out Shion with the billhook and claim Satoshi for herself...Of course Tomi may soon be single...
