Well, seeing as our choice is already made...
Hello, my name is UnderdogEmiya, and today we start our tactical guide of "What BLANK Knows About Us?"
In short, here are some of my thoughts on what BLANK likely knows about our powers and to what extent. For starters...
How Much Material Do They Have?
This is important due to the amount of fights Hiyori ends up getting into. The more fights, the more material BLANK has about us to work with.
It's honestly hard to say at first what is the starting point for their analysis. I would say that the first few fights we got into were likely too small to spread any word about us. If we want when it's likely that rumors about us began, then I think the fight against the Jotunns early on with Sigurd is where people began to take note of our odd powers, as it was also around when we received the EDGE PUNISHER title. But I can guarantee that we entered the conscience of the people when we got into the Tournament with Yuuki, as we pulled out Excalibur, created Excalibur Viviane and was overall the first demonstration for a large crowd of what a Persona could do.
After that, most of our battles were in large scale with hundreds of eyes on us. Therefore, I say that it's around this time that BLANK got concrete info on us, from rumors or else.
Big Picture
BLANK plays with rules. And so far, with their understanding in Cognitive Psience, they probably understand the following with 100% certainty.
1 - Our power is to call upon Personas upon the world.
2 - For whatever reason, we may call upon more than one Persona at a time.
3 - Personas can change with time.
The first two rules are evident by how we fight most of the time. The third one became known after the Norn's fight, where Havfrue became Undine by absorbing the essence of a Norn, though I doubt they understand the exact mechanisms behind this.
I'm unsure if they understand the difference between normal skills and Enhance Armament/Release Recollection. Likely are aware of their existence, but not of their precise mechanisms. Also likely unaware of the existence of the Velvet Room. Probably could infer we have some sort of patreon depending on how they interpretate the events from the Ragnarok with Nephren-Ka appearing, but unlikely.
Weaknesses and resistances are hard to judge as we are not usually hit with super-effective damage, but not sure about that.
Archetypes are also iffy to tell if they know about it, but I'm inclined to think they do based on their understanding of Cognition and Personas as masks.
We never had to use all of our roster at once, so I say we are also safe on the sense that BLANK doesn't have complete awareness of how much we can carry in battle.
Most Used Personas
Now, we go for a specific analysis of our arsenal in a few words, spreading my feelings over the matter. This is what I think they know about us.
-Nephren-Ka - One appearance in total, power over fire and mysterious eye power. Likely some mind reading effect?
-Urvashi - A recurrent Persona, Charm Powers, electrical powers and anti-brainwash Recollection.
-Helena - Rarely seen till now, Light Powers, Healing. Enhance Armament never used.
-Blodeuwedd - New addition, some taunt ability. Other powers unknown.
-Alice - Only used once but pretty strong demonstration.
-Urmetazoan - Dunno how much they know about this one, could accidentally lump it together with Cats of Ulthar based on usage?
-Magdalene - Worse Helena? Light powers and healing, Hama unknown due to nature of use.
-Mithras Lithurgy - Buffer Persona. I don't think they can really get what it is about from a single usage?
-Ash Nazg - New Persona, ominous aura. Death Gun Persona. Could connect it with Sauron?
-Heliose - Two uses, manipulation of crystals and weird-colored saber.
-Ulthar - One usage in total. Cat creation, transfiguration?
-Magnum Opus - Never used.
-Undine - Our most used Persona, the one BLANK knows the most about. On the other hand, we could get a Cosmo Dragoon buff depending on how Pitohui reacts next.
-Don Juan - Never used.
-Urashima - Ice powers, fisherman theme. Good water mobility?
-Attila, Ys, Zatoichi, Archon - Never used.
We also could get the Priest Persona next week to give us one additional ace in the hole.
I expect BLANK to be highly flexible with their tactics, considering the loose nature of our Personas and how our roster may change from week to week. I expect them to have counters for Urvashi and Helena as some of our usual go-tos.
A few ideas of combos:
-Urashima could do some damage with Tamatebako as someone mentioned before. I feel it will be especially effective against Shiro due to her youth.
-Urmetazoan is a wild card that can turn things in our favor if used well.
-Ys and Zatoichi have useful tricks that may force the duo to rethink their options.
-I think we may have a great interaction with Helena and Don Juan: use Emanation of Heresiarch to make things go well for some time, then use Carpe Diem for guaranteed success on a physical check, triggering the stun effect.
-Ash Nazg...is pretty sus rn, but the One Ring could turn the tide of a fight in a pinch.
