I get it. It's not Nakama power, you asshats.
Houken is a Daoseeker. He only thinks of himself and his steps on his Path. He, alone, under heaven is holy. His thoughts are pure, but he is entirely self-oriented. His own power is the limit of his strength.
Shin is someone whose foundation is built up by everyone who's left a mark on him. Everyone who fought him, pushed him to the brink. Everyone who helped him, showed him the way. He has people behind him that he cares about, that he CAN NOT, and MUST NOT fail. This is not 'Nakama Power'.
This is Human Power. This is something real humans do every day across this world. When you've given your all, everything you have, and STILL find more to keep going. When a soldier on a battlefield is about to breathe his last and still finds enough strength to pull the trigger. When a feeble mother runs through a burning building to pull her children out through the blaze even though she is burnt and blind. When a couple's car careens off the road and the husband finds the strength to pick up the car from atop his wife and then carry her miles to the hospital while his skin and muscles are hanging free. That is Human Power. This is what we are all capable of.
