[General]
The guideline regarding (Short Ver.) has been switched to ranking rule, so please remove it.
There should be "Maou Hajimemashita" in the tags I think.
Disable Letterbox during breaks in all difficulties.
Set 47392 as preview point.
[Insane]
00:11:029 (4,1) - For all patterns of this kind, I think a larger spacing may be better considering this section should be emphasized. But as this'd be a tough work, you can leave it as it is.
00:25:233 (7) - Finish?
00:31:142 (1,2) - ^
00:40:120 (4,1) - *nazi* spacing.
00:43:983 (1) - End this spinner at 00:45:574 - to match it with the end of drum-roll.
00:46:824 (2,3,4,5,6,7) - The volume setting is way too loud imo, so please reduce it a little more. And also by doing this the kiai beginning would be more emphasized.
00:51:142 (1,2,3,4) - Considering that there's a lot of hitsounds in the previous section, this section feels empty. That's because of the long sliders but you can prevent it from happening by adding claps to 00:51:824 (2,4) - .
00:52:961 (1,2) - For the same reason as above, you can add claps here. But it's still up to you.
01:10:688 (5) - This sound is kinda echoed so finish fits better imo. Adding both is a good idea as well.
01:27:051 (2) - ^
01:27:051 (2) - Considering its high SV it feels uncomfortable while playing because they're stacked, and it makes the pattern unreadable. Consider unstacking them.
http://osu.ppy.sh/ss/976681There's a lot of stuff which is applied to other diffs - especially for hitsounds. Please fix them up by yourself.
[Hard]
00:38:415 (1,2,3) - This spacing usage is really unreadable considering its difficulty and doesn't look good either.
01:00:688 (2) - I can tell why you did this but it doesn't look/flow well imo. How aboud rearranging it like this?
http://osu.ppy.sh/ss/976710[Normal]
00:27:506 (3,4) - How aboud adding whistles more?
01:04:779 (5,1) - This flows really badly because you're sticking to symmetrical pattern too much.
[Easy]
00:18:415 - You forget a finish here?
00:27:506 (3) - Is too curved imo. http://osu.ppy.sh/ss/976739
00:32:961 (1) - Too far.
01:26:597 (4) - It'd be more natural if this one is placed symmetrically as well as (1,2,3).
