The blades of vengeances have fallen swiftly. The shinobi are no more as 'Absolute Justice' has returned...now, it is the Samurai that rule the Five Major Nations!
But at what cost? Have they become the very thing that they despised the most...? Heroes and villains seem to change roles every day, but one thing is for certain - we yearn for our freedom, for days gone by where we flew the skies unhindered.
Since we no longer have a quantifiable scaling for how strong an attack is, how should I describe how much strength is needed to break out of the foam? I can't put something like "really strong force will break the foam", because it's just too vague.
This is where you can be like, it can be destroyed by strong explosives of the exploding notes level. Or, maybe someone with a rush of chakra can break free from it (i.e. Bijuu, Gates). Though, with it just being as strong as a solid rock, someone from the outside could probably break it or cut through it easier than if the victim was alone. But, yeah, I'm sure you can find something befitting.
