Why the current arc is very exhausting compared to the other arcs ?
No proper resolution
Probably because there's been hardly any resolving or falling action since the green witch arc ended. Some but not much. The current arc is also full of mini-arcs, which help to keep this weird momentum going. And it's just been going on for so many years. No other arc even comes close; it's the only one with these mini-arcs (the assignments).
Hard to feel much relief when most chapters end on cliffhangers, even cliffhangers in the middle of flashbacks.
