X’rphan is a powerful dragon that has some really impressive stats. He’s certainly not your run of the mill dragon. That being said, I’m pretty confident that Kirito could take him down in a fair fight as he’s proven in the past. Kirito is a lot faster than X’rphan and he has many different sword abilities. Kirito now even has a gun to fall back on if things get a little too frantic although I’ve never seen that be the case for him. He is the swordsman of legend after all. Kirito wins.
