Hmmn...
I have a bad feeling about what is to come tbh

Given Imu is already at his limit and Luffy has quite literally become "god of destruction" Nika I honestly think Oda might do a switharoo and have Evil Nika tag Imu out

and what is even worse is that I think Imu's gonna dip with those 4 kids and his holy knights.
From Imu's perspective, why should he go out of his way to subjugate current Nika in his current exhausted state when he can just have Nika do the dirty work instead? Moreover depending on how dangerous Luffy's current awakening is, if the success rate of overcoming it is round about zero then he'd be justified to leave Nika to his devices. Plus, from the vibe of current Nika, don't think he's gonna be able to tell apart friend or foe and is gonna attack anything in sight out of amusement so Sanji's gonna have his hands full with him.
Also at this point I'm almost certain that whatever Lily left behind is gonna be the only ting that can bring Luffy back to his senses.
Given Luffy's currently gone monkey mode, I reckon Oda's gonna go the wokong route and have it be a headband of sorts lol
