Arie swordmanship as a law of the tower

In regards to White’s sword…
Well, like all swords of the Arie Family, there is the matter of it being impossible to parry due to unpredictability,
as well as being too strong to parry.
As per the original intention of the series, it’s probably the same as how the Tower’s Rules are set outside the Laws of Physics. (say wha?)
Tower of God itself, in a sense, is a worldview where a gamified system is merged into their world,
so I think it’s possible for it to be expressed like this.
