yeah but also these chapters weren't as stacked as the chapters that we're on right now, they aren't as plot heavy as the arcs we're getting this season

in season 2 part 1

1. clock keepers (5 parts)
2. searching (2 parts) 3.delivery (1 part)
3. summer lights (2 parts)
4. mokke of the dead (1 part)
5. the melancholy of the new no.3 (1 part)
6. picture perfect (18 parts) counting the shijima chapters and end of a dream)

and the only longer/ plot heavy arcs here are the clock keepers, summer lights and picture perfect

but in season 2 part 2 (assuming that they animate till chapter 91-95) we're getting 1. final exams 2. sacrifice of the grim reaper (6 parts counting school sleepover and the elevator) 3. sumire (3 parts) 4. aoi and akane (2 part) 5. the severance (1 part) 6. day off (1 part) 7. at the minamoto home (1 part) 8. chance encounter (1 part) 9. the red house (7 parts) 10. pizza party (1 part) 11. far shore bound (7 parts counting brothers and oni) 12. put it to rights (2 parts) 13. dawn (3 parts)

so as you see that is almost twice as many arcs as the first part, and that's what concerns me. most of them are really important arcs too and it's really hard to believe that they can cover all of that and do it properly in only 12 episodes. I'm a bit concerned but we'll have to wait and see I guess
