Review Detail of FIENDCELESTIAL in One Piece: Slayer's Will

the start has so far shown to be absolutely wonderfull, just a reminder since he is aware of haki and its types he should start with getting the basics down, from what is shown in the show observation can be practised with some constantly hitting with eyes blindfolded and ears covered or makig an obstacle course and running blind through it, parkour through a jungle is another way to practise it and rokushki with soru( 10 kicks in the blink of an eye) and geppo ( kick hardenough to hit air) , the rest are kinda up in the air, life return is a body control skill that should allow to learn kami-e first and tekkai and shigan, armament haki is a bit iffy to practise just keep hitting a rock with the belief that it will break( gonna take a huge time period to even activate it) for devil fruit pls let it be the enels rumble rumble fruit ( concept of closest fruit upon death) but this aside this is a beautifull start
