YESSSS I'VE BEEN LOOKING FORWARD TO SEEING RIN'S EGO AGAIN!!!!! Its interesting how both Kaiser and Rin are Isagi's rivals and they have similar personalities – they both perform best when under extreme pressure. In Kaiser's case he destroyed his pride in response and acknowledged that Isagi had become the field's leading actor. The old Kaiser would never imagine this playstyle of fading into the background to shadowing Isagi. He never would have resorted to working with the Blue Lock members.
In contrast, Rin's response to Sae or Isagi is to hone every bit of hate and despair and frustration and focus on one thing: finding a way to destroy them. Bringing out their best plays and targeting the point where he can make it all fall apart.
Kaiser and Rin really make you appreciate the importance of a rival. They were both much stronger than Isagi at first. But now Isagi is strong enough to force them to evolve or get left behind. Which is funny because that's exactly what Isagi did. He saw these two incredible players and decided the path to getting stronger was to make them his rivals and devour em.
Last few thoughts. Its cool seeing how Isagi's basic abilities have leveled up. In the Karasu/Otoya vs Rin/Shidou match, Isagi couldn't deal with Karasu's ball possession. Meanwhile Rin was able to deal with Karasu by parrying his arms away. And now? Rin does the same thing reaching out to block and Isagi is able to knock his hands away and win the 1v1. I love lil details like that and the manga has a ton. Also Isag forcing Kaiser to make the first move and then shadowing him after is plain nasty. what a move.
There are a few things I'm looking forward to. Charles is probably gonna evolve. Ness might too in order to keep playing with Kaiser. If the star change system is used then we'll be able to see how Isagi deals with Loki compared to before when he was completely outclassed. Lots of fun stuff!!!
