Has time travel that eventually makes sense.
Follows multiple characters but in a way that for me actualy adds to the story in way that dont ruin it.
Despite main character becoming op he still faces enemy's that he "struggles" against but not due to handicapping himself for extra difficulty.
Most of the things mentioned by the author from what I've read so far ends up being meaningful and not throw away stuff.
Honestly just a real good read.
The author does not completely stick to cannon, in fact around chapter 230 he completely blows the head off cannon.
Not going to spoil anything but after what he did around 590 I lost interest due to the event. Normaly once I get this close to the end of a book I finish it. Barring certain things such as what happend.
