An unnoticed KaixJulia implication from G-rev?
Just in case you overlooked. There's this 'not so famous' scene from the G-revolutions.
I always wondered what he thought about Julia from up there. Kai's observations of battles are impeccable and he recognizes a blader's potential and strength. When Julia and Raul defeated Tyson and Daichi, I'm assuming; based on the fact that he was freaking hell-bent on defeating Tyson; he developed some kind of respect for Julia's blading skills since he thought Raul's moves were childish in the match up against him and understood Julia was the one who was carrying the team. I feel, at that moment, he even anticipated that, F-dynasty was going to be in the 3rd place beating the White Tiger X and the PPB All Starz.
Now again, he was dead-set focused on beating Tyson in G-rev and Kai being Kai, wouldn't let anything else occupy his mind. The least of all, feelings or stuff like that. He really deserves a season four to develop relationships with characters apart from the Blade Breakers and the Blitzkrieg Boys!
