Spoilers for Chainsaw Man part 2

Recently thinking about how the War Devils power works, some thoughts came to my mind:

-Yoru's wappons are "weak" beause she is a devil and does not feel guilty for anything, so she needs Asa to make powerful weapons for her.

-Yoru might have come back only after the Gun Devil Arc because it was the fist time in ages that humans saw a war, making then remember how terrifying it is.

-Yoru doesn't know how todays human interactions work because she probably was defeated after World War 2 and was "Dead" since it.

These show us how dependent Yoru is on Asa , not only for the plans that she have but also on a fisical way as Asa is not only perfect to her because she is a teenager who interacts with her school in a way that almost nobody cares for her, thus making her a good "observer" on how things work, but also is a subject to her manipulations on making her wapons as she does not feel guilty for anything human at least. Thing is, Yoru wants a Nuclear Wapon, but how shes gonna get it?

By three means:

-Asa will either become a great friend of Yoshida and kill him making him a weapon.

-Yuko will continue to live with Asa until she does something really unforgiving to her and kill her while Yoru whispers to make her a Nuclear Weapon.

-Yoru will become some type of friend to Asa, and in a circumstance were Denji or Yoshida and his Unknown Organization tries to murder then in a all out war against they and the newly revealed Horseman, she will kill Asa and make her a Nuclear Weapon.

Its kinda hard to know what exactly how as it can be something really diferent than this like, Yoru killing Death Devil but as death is something that cannot be denied, it might return
