I'm all in for backstories especially with mysterious characters like Kuma, but they should be presented orderly and in a comprehensible fashion, not spread out to 10 chapters with each section containing filler nonsense. Our clown of an author indicates he's short on time but is still hellbent on wasting everybody's time with this nonsense.
And let's say you want to revisit Kuma's flashback, now you gotta reread the entire arc again just to grab the full picture.
It's jut counterproductive in all areas
