00:58:499 - honestly you could spruce up this pattern a bit because it feels underwhelming to just play a mono when places like 02:12:617 / 02:41:293 represents it a lot more nicely

01:06:661 - i don't think there's anything in the song worth enough to represent this as a kdkdkdk, you could probably make it something like a kdkkdkd for the improv to flow a bit better

01:25:963 - you could make this a don to have the same progression you did on 01:10:852 where it goes K ddddK dkddK but the other way around

same for 02:40:080

02:33:573 - nitpick but could maybe change the kkkdk on this pattern so you don't play kkkdk twice in a row?

02:12:617 - should probably get more feedback on this but for me at least i was getting a bit thrown off by the very harsh volume changes on these patterns even though i get what you're going for

00:58:499 -
02:41:293 -

02:57:176 - the repetition idea here is pretty nice but you could maybe switch up 02:59:161 a bit so it doesn't drag on the same pattern for as long?

03:02:691 -
03:13:279 -
03:16:808 -

04:05:227 - maybe move this to 04:05:448 so the improv for the vocal to flow a bit better? more of a nitpick though

i think the kiai structure is alright but theres some things i'd do to emphasize the improv a bit more

i.e. adding a note in places like 01:02:691 / 01:09:749, you could honestly even make 01:09:970 a triplet for some progression from muzu
01:13:279 - you could add a note here and change 01:13:941 to a kat, this break works for muzu but it kinda breaks the flow on the oni
01:16:808 - maybe make this another pattern (like dkd) so you don't play kkd twice?
01:18:573 - triplet here would add a nice flow and separate it from muzu a bit more (i would probably make it something other than a ddk though)
01:20:338 - i would remove this to split the pattern because this one in specific is relatively longer compared to the others
01:23:646 - triple here and a note at 01:24:308 for consistency on the structure suggested at 01:09:529 -

same for the other kiais where it applies

01:36:220 - there's enough going on in the song to represent it more than 5 1/1s in a row, you could add a kat here and even make 01:36:882 play something like the other drum improvs where it goes kdd/kkd

same thing for 01:50:338 but then only have 01:50:999 be a kat instead

01:44:823 - you can start some improv here to avoid the same issue as 1956627#4541359

01:54:308 - this pattern is considerably longer than everything else on this section so you could remove it to split the pattern into 2 (maybe add a note on 01:55:301 so the pattern is not only full 1/2 like muzu as well)

02:39:529 - note here for consistency with 01:25:411

03:01:146 - everywhere else you placed notes where it would follow the vocals but only in here you switched it up to go only for the drums, i'd change this part to play something like 03:18:352 so this weird one off doesn't happen

same for Muzukashii

03:09:088 - more of a nitpick l but i think removing this would play nicely onto the structure

03:19:896 -> 03:21:220 - everything i've said so far was to differentiate from muzu but i think this is the one part where you should do the same as it, the vocal has a lot of emphasis on the song rn and on oni it just kinda disregards it for this section

03:21:441 - more personal but i would remove 03:22:323 and 03:23:646 to give some sense of progression from muzu towards inner oni (there's also a mod for muzu to address this)

03:38:867 - note here to follow a structure with the vocals where they all do 3plets? if you change 03:40:411 to kkd it also adds some nice contrast to the ddk that comes up later

and since you were following strictly the vocals in this little break i think you can remove 03:42:617, keeping 03:44:382 to define the break should be fine though

same for Muzukashii

04:26:293 - should also be a finisher for consistency with the other crashes

same for Muzukashii

same kiai structure ideas as oni, have a few things in mind to add a bit more emphasis on the vocals and improv

01:02:249 - adding a note here for consistency with the 5plet at 01:15:705
01:03:573 - could make this k ddd for better pitch, same for 01:20:999
01:04:455 - maybe add note here to represent the vocal so it's not just 1/1? (don't make it 2 ddks though)
same idea for 01:20:338 - but there it would emphasize the drums instead
01:23:867 - if you applied the mod on oni adding a note here would be fine for spread now

same for the other kiais where it applies

01:37:102 & 01:37:764 - notes here to avoid the same issue from 1956627#4541359 where it was just 1/1 for too long? same for 01:43:279 & 01:57:396

01:40:411 - maybe make this a kat so it's not 2 ddks in a row? vocals are different enough you don't necessarily need to use the same pattern

01:44:823 -> 01:45:485 - you can add notes in 1/2 here following the drums, the bpm is very lenient you don't necessarily need this big of a break for this difficulty unless the structure really benefits from it

same idea for 01:57:176 through 02:00:264

01:49:676 - this suffers from the same as 01:37:102 again but i think here its a bit more awkward to fit the pattern since the drums die down a bit, id say to have a note at 01:52:102 so its the same as oni but honestly its more of a bandaid fix than anything

02:43:279 - the pattern you did here is pretty nice, i think you should do the same for the rest of this section while adjusting the patterns around a bit to differentiate it from the rest of the map

02:46:808 -
02:50:558 -

02:54:088 - moving this to 02:53:867 would add some nice emphasis to the guitar

03:22:543 - add a don here for some progression? you already have one on places like 01:26:293 / 02:40:411 / 03:21:220 so it shouldn't be an issue

with how the vocals go, i think you could make the breaks happen right after the vocal stops for each verse, it would give it some nice contrast for them and it wouldn't necessarily mess with your rest moments (it's something you even did for 01:43:058)
00:18:352 -> 00:18:793
00:21:882 -> 00:22:323
00:28:941 -> 00:29:382
00:32:470 -> 00:32:911
00:36:882 -> 00:37:323
00:43:058 -> 00:43:499 etc

01:19:455 - nitpick but maybe move this to 01:19:896?, i think the kdk dkd contrast flows very nice with the vocals, with how the progression goes on the other kiais they're fine how they are there

01:26:293 - kat for variety? you already do it as K K D D on parts like 01:10:852 so i guess it would only be fair to have this part go D D K

02:40:411 -
04:12:176 -

same for Kantan

02:56:735 - mayyybe a nitpick but imo there's a lot going on already before this part and from here onward it just keeps going nonstop, i'd say you could simplify how you follow the vocals here and remove a couple notes so players on this skill level can have an easier time (even though the bpm is relatively low):
02:57:838 -
03:01:367 -
03:04:896 -
then i'd do the same from 03:11:955 onwards for consistency

(with that i'd make 02:56:735 itself and 03:10:852 a finisher because with the nerfs you could add this with no issue imo)

03:06:661 - make this a kat so it's not 2 ddks in a row?

04:23:646 - i'd say to make this a kkd for variety compared to the other kdk dkds

00:19:235 - to avoid going with 4/1 rests i'd place a note here, you could do the same to the rest of this section like:

• moving 00:22:323 to 00:22:764;
• adding a note at 00:29:823;
• moving 00:32:911 to 00:33:352 (would have to remove 00:34:235 so the layering is consistent);
• and adding a note at 00:43:941

doing this would make this section flow a lot more nicely and it also transitions well into 00:45:705 onward

same idea for 01:32:029 -> 02:00:264 but adapting the structure where possible

03:06:882 - adding a note here to follow the same structure idea would be nice as well

00:24:529 - the layering on this dkkdk looks a little weird because you're trying to follow two things at once, you could remove this so it plays the same as 00:38:205, if you want to focus on the vocals you could remove 00:24:088 - but you'd have to account for later uses as well

00:59:823 - i know there's a vocal here but since the instruments fully stop i think it could be nice to remove this note, it would also be a nice consistency for the spread to futsuu

same for 02:13:941

01:07:323 - i'd move this to 01:07:764 to layer the vocals in a bit more nicely since you already did this on 01:21:882 (you would have to remove 01:09:529 like you did it in 02:23:646 to accomodate it though)

02:21:441 -> 02:21:882
03:53:205 -> 03:53:646 and remove 03:55:411

01:23:205 - i think moving this to 01:22:985 would be nicer to the structure, you already follow this in some parts where the vocal is not present it wouldn't hurt to do it where it shows up

02:37:323 -> 02:37:102
04:09:088 -> 04:08:867

02:49:235 - maybe add a kat here for a bit of variety on the patterning for this section?

03:01:146 - you should move this to 03:01:146 to stay consistent with 02:58:058, it also goes very nicely with the vocals if you also do these:

03:04:676 -
03:15:705 -
03:19:235 -

04:18:352 - same idea as other mods about vocals, you could move this to 04:18:793 and maybe even make it a 3plet with 04:19:235

adding a note at 04:20:999 would go nicely too, you could move 04:21:882 to 04:23:646 so you can still keep the 5plet as well
