Someone can awaken their DF if their will aligns with the desire/will of the fruit's OG user.
True and will of Teach aligns with Davy because both of them are the user of Yami
I'm trying to say that awakening or even having the Yami Yami no mi makes no difference to being acknowledged as Davy Jones you don't need that to inherit his will
It's just a nice to have ( if it's the same situation as Nika if Davy was the original user of it u can inherit Joy Boy's will without having the Nika DF )
I disagree
Don't we know that there had been many who had Nika dfs in the past (since void century) but failed to awaken it?
But the moment Luffy awakened it, Zunisha said "Joyboy has returned"
It seems to me both davy and JB had common enemy in imu. Both were threats to imu and his rule. For example rocks is not anti Roger or as evil as BB was. Even in mural we see a big devil which can be imu fighting joyboy and all. Both davy and joyboy had their own wills which are different sure but it remains to be seen who was bigger evil.
Oda is quite clear with the theme ..
Devil vs Darkness vs Light
Obviously, we know that Luffy is the light and he will emerge victorious at the end.
But, whether devil is the bigger bad or Darkness is.... whether Devil comes under Darkness or vice versa is the whole debate
