mmh, so it looks like they're taking this story in that direction. Hajime no ippo (HNI) did the same thing. Having a bond means that it can be exploited to your detriment, but where there is weakness there is also strength. In HNI I think they described it as having heavy fists, not in strength, but in the heavy bonds they carry. Maybe he would be able to climb this mountain easier if he had no bonds at all, but to return alive I think having something tying you back to the ground could be very helpful.
