Once I get to impel down they lock me up and put me on level 3, I start training never stopping continuously trying to master my haki to the point where it isn't affected by the cuffs of course some of the prisoners laught at me but I continue training mastering observation,armament and my conqueror haki,but I realize I need to gather more crew mates so I keep training.

One year time skip

I wait for the moment when they start transferring ace to impel down and while the guards move up the level once they get to mine I break my cuffs break the hard and knock them out,ace looks surprised as I take the keys from the guards and then free ace while to rest of the prisoners are begging me to let them free too and they'll do whatever I want but I ignore them and go to find jimbei with ace I ask both of them to join my crew, ace said he was already in a crew as expected but surprisingly jimbei agreed and then I start going down some levels to find vivi and batholonew.

After a bit of looking I find them in level two and free them we have a emotional moment but it is cut short by Magellan as he tries to sneak attack us but we dodge they distract him as I try to find my sword after a while of looking I find sandia in his office I then come outside to see my crew and ace still fighting him, I jump in and start attacking him,it was a long battle but I managed to cut him up using onigiri after defeating him we continue going down but then we see luffy fighting dark beard.

Ace immediately joins in and they start overwhelming him even with his fruit abilities,he tries to run away but then I appear behind him and slash him leaving him to die,luffy looks surprised by he knows there's nothing he can do about it, as we leave impel down there's an army of marines waiting for us, I use my conquerer haki to knock out the fother while the some of the vice admirals and the admirals are the standing me,the crew,ace and luffy all attack but I know we can't win but im holding them off for someone to arrive and after a couple mins of us fighting and taking out most of the vice admirals except garp,we see a ship we a huge man sitting in it and I smile knowing it's the white beard crew and I know that a war is gonna start.
