00:13:088 (38,39,40) - d k k , to fulfill the method 2 kats for each completed beat that you have assigned in Oni.
00:13:690 (40) - could remove note to give emphasis, since this kinda makes no sense after putting a break
00:26:161 (87) - Maybe you could delete this note so the pattern would be ddk-k which is similar rhythm as nearby patterns like 3notes-1note
00:29:953 (98,99,100,101,102) - using finishers in a pattern like this one breaks the RC, so i suggest either making the last note a normal note or deleting 00:30:179 (101) - to keep the finisher
i'd also change 00:29:953 (98) - to k so it would be easier to play for muzukashii-level players
00:32:969 (102,103) - shift these two notes 1/4 later appears to fit the main instrument much better
