-Your EX projectiles are restricted wrong.
-Power particles are misaligned for power charging.
-Can't roll forward while running.
-Rasetsumaru's laughing winpose sometimes plays the wrong voice clip for it.
Fixed everything but the laugh, I'm still on the fence about it. This is where it comes from (watch until the end):

I agree it doesn't really fit the animation on source, I want to see if I can come up with a new animation that fits the voice sample.
Thanks for the reports 
This char feels...indecisive and excessive. Like, you couldn't decide on one final product, and the result is a mashing up of core mechanics. Which in turn, makes him overpowered honestly.
Hard disagree with everything in here. Especially with the overpowered part, but I'm also very decided on what I want these two characters to be.
He can do a Rage Burst, on top of CC, and power charging... While I'm not the most familiar with SS games, doesn't the way you have it here in the SS games disables the meter after it runs out/if you miss Issen for the rest of the match?
It does. In fact, one of the first versions of this install super made you unable to charge meter after you rage exploded (it should be around MFG discord server). It also was like in source: a combo breaker that you could use while being hit on the ground. I think that was way too intricate and decided to make simpler. It isn't a combo breaker, and it doesn't break your power gauge. It's just an install with a little burst that sets you on neutral.
You have a core mechanic from K-Groove here, that's honestly more buffed in this regard, because you can activate it whenever you so choose. While retaining the core CC from A-Groove. You can't use them both at the same time, sure. However, does that matter? He still has TWO core groove mechanics at his disposal. And the Rage Burst isn't even limited like in the SS games! If it misses, I can just do it again! I retain my power gauge. Along with having access to power charging.
You can make a case for being excessive, but that's subjective. There are a lot of precedents of characters breaking the rules in fgs. In anime games you have all sort of characters with extra special gauges. In Marvel you have characters like Phoenix who reaches special powers up with enough meter. In Tekken 7 Akuma has his own combo gauge. There's also this character in Soul Calibur VI that gets raged: Haohmaru 
Also, why does Rasetsumaru have EX moves? If PotS' style is what you're aiming for, neither he or JMM would have given Rasetsumaru EX moves. This only adds to his OP tool set.
Rasetsumaru is not a boss, but, more importantly: what OP tool set? The only thing Rasetsumaru has going for it is damage. He does insane damage, and that's intended. The problem is him not being able to open up any decent player by any means. He can't mixup for shit. He doesn't have any overheads or lows outside of his normals (his good jumping attacks have long startup also), and his buttons are not suited for comboing, as they belong to a character that mainly pokes. He also has a lot of problems anti-airing, Nagi Yaiba should require a lot of prediction and unlike Haohmaru's, hi cr.HP sucks. A lot of characters are capable of punishing you on hit if you antiair with cr.HP. His CC strings are also garbage compared to Haohmaru's. Rasetsumaru relies on spacing properly with shoulder. He lives and dies by meter because not only he does way more damage with meter, but it also improves significantly his neutral. If you're against him, just turtle and punish on block his unsafe moves, or whiff punish like against any other character.
I'm sorry but I see that you are making a correlation between having more options ("being excessive") and being OP, and that's just not how balance works, not at all. Who the fuck cares if he can Rage at will if he has these many glaring weaknesses? I put a lot of thought on how his moveset is and interacts. He is not OP by any means, if anything he is supposed to be underpowered, and if there's anything that is breaking some of the weaknesses that I intend Rasetsumaru to have, lemme know (you or anyone) and I'll fix them. Rage is not one of them, tho. Rage you leaves you a -1 (essentially neutral) and gives you a attack and defense buff (and access to Issen). The counterplay is just... Blocking. There's not 50/50s to worry about. One of the big differences between my Rage Explosion and K-Groove (even bigger than being able to use it whenever you have meter instead of filling the gauge with JD and being hit) is that there's no Guard Crush like in CvS2. Characters like Geese thrive on K-Groove because when raged he eats the guard meter like cookies. This is absent on PotS system.
This has actually started to pool over in your more recent chars. You gave Yun his buff Genei Jin, while keeping CC. Isn't that a bit excessive?
If you cut Genei Jin out of Yun, he becomes CvS2 Yun + EX Moves, which is heavily underpowered unless I break his EX moves. The idea of designing install type of supers into POTS is so characters that rely on them on source don't feel underpowered when you cut them out. Yun experienced pain when CvS2 and CFJ removed Genei Jin.
Why didn't you just do what you did with Rose? Instead of giving her Soul illusion, you made CC able to cancel into like a super move. Effective and efficient, and not redundant.
This comes back to the non-existent correlation between being excessive and being OP. Being able to cancel into CC might not be excessive, but it's very broken, more than I expected it to be at the time. As a result Rose is one of my more broken creations out there, sadly. She will experience updates in the future that integrate Soul Illusion to his arsenal and balance around that.
Yes, the version of Genei Jin you gave is better than the nerfed CC; Though if that be the case, why even have that CC there? Yang gets a pass, as his move isn't actually like CC. It's more of a double/shadow attack thing going on.
Don't worry, I put a lot of thought on having both CC and Genei Jin on the same character. You don't mind having a Super Move with two levels of strength, right? Welp, think about Genei Jin like it was a lvl 2 version of Custom Combo. 1 bar of install should never outclass Custom Combo. Seiei Enbu/Genei Jin starts outclassing Custom Combo once you have 2 bars, which fits my vision of a lvl 2 version of CC. Once again, I'll share my notes while redesigning Genei Jin:

POTS Install super moves.
*How does it work?
You can pop it off whenever you have 1 or more bars. It drains the meter and it lasts until it reaches 0. You can still use EX moves and supers, but as they drain meter too, they reduce time you can stay on install state. If you are interrupted during this state, your meter gets cut in half (A Groove). The effects vary from character to character, but one important thing is that it's super cancelable. In Yun's case, he gets safer normals all across the board, and juggles like crazy. Rose and Yang get shadows and Makoto damage buffs. This could extend to SNK characters, I'm thinking on 2003 Hero team having different install supers each one of them (excel, shadows, and max just like SF iirc).
* How long does it last? Doesn't this makes Custom Combo useless?
3 bars worth of install lasts 300 ticks (5 seconds), so 1 bar worth of install lasts 100 ticks (1,67 seconds) versus 180 ticks (3 seconds) of Custom Combo. Damage of 1 bar of install should not be higher than damage on CC.
*Why bothering?
I could just buff the fuck out of Yun's damage but I feel it would dumb down the character a lot.
*Does having two installs on the same system makes up bad character design?
Having two install type of moves is not unheard off. KoF XIII has Hyper Drive Mode and install supers on both Shen and Hwa Jai, and I think highly of that game when ignoring the balance issues.
If you find a string of lvl 1 Genei Jin that makes more damage than Custom Combo (virtually outclassing CC), lemme know and I'll fix it.
If your plan is to update Genjuro like this... I recommend against it.
I think I said it before, but the changes on Genjuro will be so significant that I intend to preserve the current version updated too.
You need to decide on mechanics(especially core ones) and stick with it..
I already decided.
Because this feels off honestly. Overall, he's solid. However I can't ignore the fact that he has far too much at his disposal. Throwing him off balance.
We'll have to agree to disagree when it comes down to what we think its "too much at his disposal". For me, adding a command grab to Terry was too much, for you it wasn't. Now, does adding a command grab to Terry throws him off balance? Not necessary, just like having Rage doesn't necessarily throws Haohmaru/Rasetsumaru off balance.
I feel that Shitatari is kind of in the redundant category. He loses 20% life to gain 1 bar of super, when he already has power charge. Shitatari was kind of a Samurai Showdown specific move because of the game mechanics. When Chazzanova did his version, he made the move be a time-limit power boost, which was a better alternative.
Welp, Shitatari is part of a dynamic related to Rasetsumaru's different knockdown times.
When you hit cr.MK or cl.MK you have four options:
When you don't have meter:
* Special cancel into light shoulder and link cl.HP for the most damaging non-meter option but really short knockdown time (no oki, no repositioning).
* Special cancel into proximity anti-air for medium damage and medium knockdown time (the best option for okizeme).
* Special cancel into light pocket sands for the lowest damage but the highest knockdown time.
When you have meter.
* Special cancel into proximity anti-air and super cancel into Tenha Dankuu Retsu Zan for the most damaging meter option.
Why does this matter for Shitatari? Because of the high knock down time, when you special cancel into pockets sands you to get to use Shitatari without being punished, gaining a lot of meter. If you try to Power Charge after the knock down you won't even get one bar. If you Shitatari, you get about one bar and a third. Meter matters a lot on Rasetsumaru because of how much his damages spikes with it.
Now, is it worth? Welp, it heavily depends of the state of the game. POTS System has huge power gains all over the place so its not like you desperately need to use Shitatari to gain some meter, but the option is still there if you want to pressure early on the game. I really don't have that much of an issue with a move not being optimal, tho.
