The top difficulty really starts picking up the pace again at 02:22:187 by building up with triplets. I would love to see this in the inner oni aswell.
Currently it kinda plays like the oni does with a few less breaks, but overall I think a few more triplets could be added to pick up the pace here, just like you did in the top difficulty!
Adding notes at spots like 02:23:514 and 02:24:668 would be a great example to this in my opinion ^^
I think it would be nice to connect the 2 triplets by adding a note at 01:43:707 to increase the difficulty here compared to the oni.
Another option would be using isolated 1/6 quads but I'd understand if you think that'd be too harsh for this bpm.
I do really think this little part can be a lot harder on a 6* inner, even without using 1/6 since the song suggests something dense.
This might go a bit against your mapping style in this map but I think the outro would be great if you remove 03:10:061 to put extra emphasis on the last few finisher notes and make for a better ending effect.
Personally, I also think it'd sound better if you'd having something like Xx xx xxxxx XXXX starting from 03:08:369 for example, but ultimately you should go for whatever sounds best to you!
I think it'd be nice to either move 02:14:793 -> 02:14:908 and switch to kd in contrast to dk at 02:14:562 or just straight up add an extra note at 02:14:793.
Which one of the 2 comes to down to preference, but I think portraying the sound at 02:20:446 in some way would also be beneficial for the emphasis on 02:20:562.
You could cut 01:27:009 for example, or any note around that to make this part a little less dense? I think this is definitely a calmer part in the kiai melodic-wise and a small cut in the big pattern would emphasize that well in my opinion.
This would also give more light to the small melody at 01:27:224 by making the a quint on its own, same can be applied to 03:09:867, same idea melody-wise but different tone in the music!
Just gonna respond here instead of making a post since I think the kiai breaks were mentioned here earlier, I feel like they're extremely weird and awkward personally.
Especially since a spot like 04:11:235 just has a very clear instrumental sound. I understand that this map is following mainly vocals, but ignoring this ruins the flow for me and makes it sound very odd.
I recommend at least filling up the gaps where a guitar is playing like 04:11:235
