It is nice to have friendly chat even once in a while. Flaming is pointless and makes yourself looks stupid anyway.
Naruto activated Demonfox Eyes just before summoning KBs. So battle mode is plausable answer. But still he uses Kyuubi trait without any signs of losing control!
Demonfox Eyes as future Uzumaki bloodline limit doujutsu would be nice. I wonder what aer they can do? See chakra? Predict movements? Instill ferar in anyone who cross sights with user? Just looks cool???
