Something needs to happen for Ippo to cross that line Takamura made next to the water where he has to discard his humanity. We've been told that Ippo lost because he didn't go into his fight with Alfredo with the right mindset. With the mindset that the world level requires and the training he's done, he might even be able to carry Ricardo's jockstrap.
I don't know if it's Ricardo crucifying Miyata, Ricardo burning down the Kamogawa gym, or Ricardo stealing away Kumi, but Ricardo has to do something to get that switch flipped.
It's interesting that Ricardo has made multiple mentions of the division revolving around a fighter that isn't even active anymore and that all he wants is a challenge. He might just put two and two together and start trying to get Ippo back in the ring.
