Navigating the Cognitive School: A Practical Walkthrough
I've spent more time than I care to admit in Maruki's Palace, mostly because it's the penultimate one in Royal and you can't just skip ahead. The dungeon itself is a multi-layered school building that shifts between different floors depending on which cognitive reality you're in. The exit puzzle alone will eat up thirty minutes of your evening if you're not careful. The core mechanic that makes this palace different from every other one you've fought is the Maruki's Ideal World toggle. You can press the touch button to switch between two cognitive realities at any point outside of combat. One is the normal, slightly surreal school environment, and the other is a utopian version where everyone is smiling and things look... off. The trap is that both versions present different puzzles, different pathways, and sometimes different enemies blocking the same route. I wasted an entire night trying to solve a lock puzzle in the normal world only to realize the answer was hiding in the alternate reality on the same floor. The treasure is located on the third floor of the school section, behind a puzzle that requires you to interact with four statues. Each statue corresponds to a day of the week, and you need to arrange them in the correct order based on clues scattered across the palace. The clue system here is genuinely well-designed but easy to miss if you're rushing. I found the first one in a locker on the second floor that isn't even on the main path, and without it the entire puzzle stalls out.
Boss Strategy and Realistic Approach
Takuto Maruki has two distinct forms and they require fundamentally different strategies. The first phase is essentially a standard persona boss fight with some elemental quirks. His primary attack pattern revolves around dealing Almighty damage, which bypasses most elemental resistance builds. This means your standard fire or ice spread will feel satisfying but won't break through his defenses efficiently. The second phase is where most people get stuck. Maruki shifts into a fully automated combat mode where he heals himself aggressively and summons support Personas that can steal your buffs. I spent three attempts on this before realizing that the key isn't to DPS him down but to systematically remove his buffs and suppress the summoned Personas before they stack too many positive effects on him. Use Skeleton Key passes from Take Mi Na Bere to steal his buffs back, and focus fire on the summons rather than Maruki himself for the first few turns. Here's something the walkthroughs don't usually emphasize: Maruki's second form has a hidden weakness to Gun attacks that many players overlook because the visual effects are the same across damage types. If you have Joker equipped with a gun weapon and the Right Stab or similar skill, you'll melt his HP much faster than using physical strike-type attacks. This alone cut my second attempt from twenty minutes down to about six.
What to Prepare Before Entering
By the time you reach this palace, you should already have fused at least one of the later Arcana Personas. Specifically, I'd recommend having Motarus or Thoth in your lineup for the Almighty resistance, and a decent support Persona like Narcissus for healing since Maruki can apply several status ailments that bypass standard cure skills. If you're running a fully stock party composition, consider bringing backup healing items. The battle can drag on, and running out of Curaja charges mid-fight is genuinely annoying. The palace also features a Confidant check with Yoshizawa that becomes available during exploration. It's not mandatory but skipping it entirely means you lose access to a useful skill later on. I don't recommend rushing past it, but it also won't block your progress if you absolutely need to move forward.

Common Pitfalls That Cost Me Hours
The biggest mistake I made was assuming the palace layout was static. It's not. Certain passages open and close based on which reality you're currently viewing, and some areas that seem accessible in the normal world become completely blocked in the ideal world. I spent nearly forty-five minutes retracing my steps only to realize I had to switch realities mid-floor to proceed. The game doesn't tell you this explicitly, so just keep that in mind whenever you hit a dead end that shouldn't be a dead end. Another thing to watch for is the Cognitive Dissolution mechanic. If you stay in the ideal world for too long without completing objectives, Maruki's cognitive influence starts affecting your party members visually and can trigger unexpected enemy encounters. It doesn't cause permanent stat penalties, but it does clutter your map with phantom shadows that waste time and resources. Toggle back to the normal reality if you notice the screen tint shifting or if extra enemies start spawning more frequently than usual. The palace as a whole is fairer than it looks once you understand the dual-reality system, but the final boss fight absolutely demands preparation. Don't walk in blind relying on level advantage alone. The Almighty damage output is designed to punish under-leveled parties regardless of how many times you've beaten the previous palaces. A solid party composition with proper resistance coverage and a strategy that accounts for his buff-stealing mechanics will make this fight routine rather than stressful.
