I am pretty thorough, so don't be annoyed if I point out a lot of issues. A lot of times they are just my opinions, so feel free to object to them. :3
d = don
k = katsu
D = big don
K = big katsu
[General]
There really aren't that many problems as this is pretty much a polished, rankable mapset; there are note placements which I disagree with, but since mapping is inherently a subjective thing I don't want to impose my ideas on you.
Because this spread is good however, I will nitpick it to high heaven. Hereby commences nitpicking.
There are spots which... are not issues as such, more of things that I feel are off, or could be made better. Which are listed below.
Intensity: 00:23:272 to 00:46:545 as a section is less intense than the rest of the song on the whole, because of the lack of drums. However, you have employed note placement or grouping techniques that map to vocals/synth that makes this equal, or even more intense than the rest of the map.
For Kantan, it is offbeat patterns: 00:37:090 (2,3,4,5,6,7,8,9,10) for example.
For Futsuu, it is offbeat placements: 00:26:727 (9,10,11,12,13,14,15,1) for example.
For Muzukashii, it is a combination of offbeat patterns and note density: 00:28:181 (17,18,19,20,21,22) for example.
Oni is okay.
Personally, I would remove some of the notes and patterns here to lessen note density. This section is sorta a place where the music takes a breather, and I believe it should be mapped as such as well. Of course, change or no change is entirely up to you.
Kiai time: I don't agree with your kiai time usage. (Note: I don't
agree with it, not I don't
like it or it isn't correct.)
Personally, I would place them from 00:58:181 to 01:21:454, and from 02:08:000 to 02:54:545. I DO understand WHY you have put them this way, but in terms of song
structure they don't fit well. (00:58:181 to 01:21:454 is four similar 4-bar phrases; 02:08:000 to 02:54:545 is eight similar 4-bar phrases.)
That's about it for general stuff found across all 4 difficulties. Onto the specifics! :3
[Kantan]
01:25:090 (93,96) - because of the really loud snares, I would map this a k instead of following vocals.
02:35:636 (6) and 02:53:090 (26) - you've been keeping at the 4-2 clumped notes, joining them together would be inconsistent.
[Futsuu]
01:17:818 (75) - could be changed to K to match the faint vocal shout in the music
02:28:909 (51,52,53) - change to dk d would match drums and synth pitch
02:34:181 (67,71) - change to d to match drums?
02:45:818 (103,107) - ^
[Muzukashii]
01:16:000 (91,92,93,94) - change to d ddk for slightly better flow and for matching drums
01:25:818 (133,134,135,136,137) - how do you feel about kddkk here? k would match vocals' pitch better
02:29:272 (103,104) - change to dd to be consistent with 02:38:909 (147,148,149,150,151,152,153,154)
02:31:272 to 02:33:818 - this section is mapped very regularly, which is not consistent with the offbeat patterns used in the kiai. They are mapped suitably and they function, but they don't merge well with the rest of the song.
02:44:909 (179,180,181) - change to ddk to match synth pitch, and k would match snares as well
02:47:636 (193,194,195,196,197,198) - how does k d kkd k sound to you? Matches synth pitch better, but makes the muzu more difficult
[Oni]
01:03:636 (51) - could be changed to K to match the faint vocal shout in the music
01:43:818 (39) - change to d to be consistent with 01:38:000 (14)
02:31:636 (139,140) - change to kd would match synth pitch
That's about it! I did say note placement was good, didn't I?

Nitpicking complete. :3
There you go! Hope you find this mod helpful, and good luck beatmapping!
