Questions 02: What's the limit of Berserker's ability to "turn any object into Noble Phantasm"? Will it work on a battleship? Why not just hijack a computer and become an existence like Sky*et... please put a stop to my overflowing dreams. [Kyoto · Musashibō-san]

Nasu: In theory it's limited to objects that are weapons. An aircraft carrier's role as weapon transportation is ranked higher than it being a weapon, so it shouldn't be counted as a weapon. Something like that. What's your opinion on this, Uro-san?
Uro: For Berserker, the Noble Phantasm can only be activated for things he recognizes as "this is a weapon." In that case, if he is skilled in wrestling, can he... turn a steel chair into a Noble Phantasm?
