SMTVV - Arahabaki Gogmagog Strategy

I'll proceed to explain this absurd strategy as quickly as I can. Youtube has a limit of characters for video descriptions.
We start by taking advantage of Horus, whose innate skill ("Eye of Horus") gives Impaler's Animus for free to whatever demon he switches with.
The demon we swap him with is Arahabaki. This guy's innate is absurdly good; he copies any buffs and debuffs you apply to him into whatever demon/s you switch into battle.
This effect remains active for as long as Arahabaki is kept on the field.
What does this mean exactly though? Well, that we can essentially copy-paste Impaler's Animus into whatever demons we throw into the fray without wasting press turns or skill slots with the actual skill.

So, after setting up Impaler's Animus on my Arahabaki I work on farming a few extra press turns.
To do this, I use Luminiscent Mirage with the Nahobino which guarantees he'll evade the next enemy's attack.
This oddly specific action is required to activate a unique passive you get from one of Tsukuyomi's essences. It's called "Intercalation", and as you might have guessed, adds a press turn to your next turn if on the turn before that you have Nahobino evade an attack.
On top of that, I also make use of Yoshitsune's innate, which adds a press turn to your next turn if on the turn before that you make him waste 2 press turns, which I do by activating Hariti's Dark element nullification.

This is the first RNG check I had to deal with out of many.
If Satan killed Yoshitsune, which surprisingly did happen some times, I would lose a press turn and by extension restart the fight.
I really wanted to get to the 2nd turn with 6 press turns. They extra 2 press turns were going to be my safety net to leverage the rest of the RNG checks I would have to deal with.

So, dawn of the 2nd turn.
We have an Arahabaki with Impaler's Animus, our precious Nahobeeho, and 6 whole press turns.
Arahabaki doesn't need to do anything here so he skips, giving way to Nahobeeho who activates his Magatsuhi Skill, "Omagatoki: Strategize".
This skill is fairly simple; it makes it so swapping demons and Pass'ing an action won't consume a press turn.
This can be very, very, VERY useful in combination with other innate skills which I'll talk about later.

With Omagatoki: Strategize at play, we can start to get the ball rolling.
I swap Belial in and out 3 times. His innate DEBUFFS your party's Defenses, just as if an opponent used -̶M̶a̶r̶a̶k̶u̶k̶a̶j̶a̶  Matarunda on you.
It doesn't affect the innate's owner, which in this case is Belial, but that doesn't matter.
Reducing my party's defenses wasn't exactly mandatory, it was meant to secure the next part of the plan.
I swap in Loa, whose innate increases the success rate of ailment-inflicting skills.
With Copy-Paste Arahabaki, Omagatoki: Strategize and Loa on the field, I start to swap in demons with the Virus Carrier innate skill.
"What does that do?" you might be wondering. It makes its owner not waste a press turn if they manage to successfully inflict an ailment on 1 or more opponents.
There's a total of 5 demons in this game who have it, and I make use of every single one.
I have each Virus Carrier hold a different AoE ailment-inflicting skill hoping that Satan, who possesses an Almighty counter skill called "Adversary" kills each of them.
"But why would you do that? What's the point?" you might ask. Each time one of your demons is killed, your Magatsuhi Bar is filled by about 15% if you have a miracle for the Nahobino called "Vengeance".
If you haven't understood, I'm basically replenishing my Magatsuhi Bar which I spent activating Nahobeeho's "Omagatoki: Strategize" earlier as much as possible, in a way that doesn't make me waste my press turns.

This part of the strategy was easily the hardest. I had to restart from scratch so many times, because as I mentioned at the top, sometimes ailments like Sleep would proc on Satan, which in turn would make his Adversary skill not activate, and we absolutely need him up and running to kill our demons and refill our Magatsuhi Bar.
You guys have no idea how nervous I was here. This was the very first time the strategy was actually working as intended.

Anyway, after our 5 Virus Carriers died with our press turns mostly intact and our Magatsuhi Bar filled to the brim, I proceeded to swap in and out Azazel and Tzitzimitl.
These 2 have innates similar to Belial's. Azazel's debuffs your party's Attack, while Tzitzimitl's lowers your party's Accuracy.
We do these a few times until we get to -3 Atk and -3 Acc.
Once we get there, we swap in Amanozako, whose innate turns the stat buffs applied on the party into debuffs and viceversa.
Yes. We basically went from -3 Attack, Accuracy and Defense to +3. All in the span of 1 single turn, and without spending any press turns to achieve it.
Crazy, isn't it? It's honestly ridiculous and extremely hyper specific what all these innates do.

So, at this point we have our Magatsuhi Bar full, an Arahabaki with Impaler's Animus, Omagatoki: Strategize in effect and +3 in Attack, Accuracy and Defense on fighting party members. All buffs that Arahabaki will copy into any and all demons we swap in from now on.
We're approaching the moment of truth; I swap in Cerberus, a demon who has the Magatsuhi Skill "Omagatoki: Adversity".
Now this is... this is stupidly good for offense-oriented purposes.
It basically multiplies the damage dealt by all of your party members based on their current HP and their max HP.
We can take full advantage of this by having high-leveled allies at 1HP make use of it.
Obviously, I prepared a demon accordingly.
A demon that is BIG.
A demon that is STRONG.
That demon is the one and only Gogmagog, but I like to call it GogmaGOD.
This beautiful free-flowing giant of love, this absolute weapon of mass destruction, is the ace under the sleeve.
His innate buffs his critical hit damage based on the number of weaknesses your party members have.

It might be a bit late to suggest this, but why don't you go and check my Nahobino's weaknesses again? ;) ...
Yes, that's QUITE FUCKING CORRECT; I GAVE HIM A SLIME ESSENCE.
5 FUCKING WEAKNESSES ON TOP OF ARAHABAKI'S 4 WEAKNESSES PLUS GOGMAGOD WHO HAS 3 OF HIS OWN.
And at the end, everything comes down to one last piece in this sickeningly complicated puzzle: Slime.
Yes, the 4th party member that gets a front row seat in the spectacle that is Satan's ass-beating is just a Slime.
I mean, come on, I just said it; Gogmagog's innate buffs his crit. damage based on the amount of weaknesses in our party.
Of course I'd take advantage of that, specially when we have Omagatoki: Strategize to swap demons in and out entirely for free.

Anyway, after all is said and done the moment of truth is finally here.
Our party is conformed by:
An Arahabaki with Impaler's Animus, Omagatoki: Strategize, Omagatoki: Adversity and +3 Attack/Defense/Accuracy.
A Slime.
The main character, Susano'o Nahobino, who funnily enough has taken the back seat for the most part only providing support and not much else.
And GogmaGOD, who has all of Arahabaki's buffs on top of his Vengeful Might.
At this point I've done all the setup I could think of doing. The Heart of the Cards will decide my fate.
I have GogmaGOD use Figment Slash.
I swap him out because Impaler's Animus only lasts for 1 offensive action.
Then I swap him out and back in to re-apply Impaler's Animus courtesy of Arahabaki.
Then I have GogmaGOD use Figment Slash.
Then I swap him out because Impaler's Animus only lasts for 1 offensive action.
Then I swap him out and back in to re-apply Impaler's Animus courtesy of Arahabaki.
And then the rest is history.
