stuff about the intro:

you could get rid of 00:03:275 (9) - 00:05:675 (18) - , this way you'll be able to map the prominent piano at 00:03:875 - while still have 3/2 breaks.

00:05:975 (19,20,21,22) - this can also follow the piano, I don't really understand what it's trying to follow now but the piano quad sound is so evident that it's a shame you're not mapping it. you can do kkkd and leave 00:06:575 (22) - empty for a more interesting rhythm

00:09:575 (35,36,37,38) - this doesn't work honestly, breaks the structure you built and the vocals aren't a reliable layer to map, I recommend sticking to the instrumental and most importantly, stick to a consistent structure.
starting from 00:08:975 - you could do something like k dk kd ddk d, with doublets just like on the first half of the section

00:11:375 - starting from here, more layers get added so it makes sense to have a variation in rhythms, but I think you should still keep a proper structure unless the song screams for it. for example, 00:12:125 - should still be mapped like on the first half instead of 00:13:025 (47) - . (same 00:14:525 - )

this is the only part I'll talk about for oni, since the rest is too dense for me. I however noticed that you really struggle with giving proper emphasis to the rhythms of the instrumental, some sections are just too overmapped even for 1/4 only (00:37:250 (11,12,13,14,15,16,17,18) - this is clearly 1/2 yet you map the notes in between taking away all the emphasis, to give an example).

You should absolutely give more attention to the actual rhythms, because this song has interesting ones.

01:33:440 - start the kiai here for oni andf hell oni so that all diffs are consistent (it also makes a lot more sense lol)

add "version" to tags so that people who don't just type "ver" can also find it.

very good

yes

two things I noticed from playing the map once:

00:59:707 (162) - 01:02:303 (28) - kinda unreasonable to pretend from players to be able to hit the notes immediately after these sliders, I recommend making them shorter or removing them. because they ruin the playability of the section.

02:10:160 - this pattern is so hard and so sudden, it's the only instance in the map where you use an offhand like this, so I recommend reworking the colours for playability, as it's a flow killer in my opinion. you can keep the offhands, just don't make the pattern end with kkkkddddkk when nothing else in the map is close to that!
playability and pattern f low at this bpm is really important, and pitch accuracy shouldn't be prioritised over that.
