Unbound:: 自分's unbound to any harm 相手 sends
Unshackled:: He cannot be defined by mortality/death
Liberated:: All hostility simply fails to reach 自分
Liberation Sword: Forces the liberation of 相手's ego/mind
Unassailable:: 相手, is simply put, transcended utterly
After spending as many kalpas as the ganges river of the underworld, 自分 finally reached [Nirvana], transcending the very essence of existence as he's completely liberated from all concepts, reaching [The Void]
[Void Liberation]: & yet, as the narrative comes to an end, 自分 transcends further above, reaching [The Primordial Void], now so utterly unassailable 相手's presence is insignificant to him
