??? Corridor

You will be automatically brought into the Palace on 1/12 for Sumire’s awakening and story progress.

You will need an ID card to unlock the door. Head into the Auditorium.

It’s a very straight forward path. Once you go through this door, you will be faced with the strong shadow who carries the ID card you need.

??? Auditorium

The battle is very easy. Just use your best damage. Use the ID on the door and you can now proceed.

??? Warehouse

Climb up the boxes and hook yourself up.

Keep climbing and you will come upon the elevator taking you to the Monitoring Room.

??? Monitoring Room

There are 2 strong shadow to defeat. Make sure you bring a healer.

After the battle, you will need to investigate the Mementos before continuing here. Return to the real world.

Return to the Monitoring Room on your next infiltration. Once you have checked that the cables are gone, you can go through this area.

If you keep moving on, you will come upon a locked door which requires you to answer a question about Maruki’s life.

In the room west of the locked door, go all the way to your left and you will find a vent that you can crawl through.

The first Will Seed first is right over on the other side.

Outside the Will Seed Room you will be able to jump down the cables and head back to the main area.

Head all the way south and you will come upon a locked door. Go to the room next to it and there is a vent for your to crawl through.

In the locked room, check out the CRT TV and choose to watch video.

Now head back to unlock the door. The answer should be “his lover”

The elevator is not working so head over to the east to receive the map and go through the door.


Research Ward

This is a very straightforward map. Just save your game in the Safe Room and head for the spiral stairs in the middle.

When you are on the 2F, Mona will alert you to a room which gives off the same vibe as the Video Room in the earlier area. Your goal here is to reach this room.

In the room south, check out the Mysterious Enclousure.

Head for the other spiral staircase on this map.

On the 3F, you will come upon another security locked door.

Go to the other spiral stairs in this area and head down. You will find yourself back to the 2F. Head the stairs opposite where you landed and you will reach a room with a treasure chest. Lookout for the spot to use your grapple hook and there will be a vent for your to crawl through up there.

Open the door and you will see a shattered glass. Choose to break the wall.

And now you get your Second Will Seed Room.

Now head back down the stairs to the room with the video you need. Check out the TV to activate the video.

Head back to the security locked door and select “evidence”


Exam Room

Approach the reception and speak to the Shadow Receptionist.

In the exam room, you will have to choose the correct answer that Maruki wanted. If you choose the wrong answer, you will be faced with a battle.

Talk to the team in the consulting area and the people with speech bubble around the room before making your decision. Choose B – Go Get Help and Take the Red elevator.

In the second room. You just need to talk to the people in the area and then choose C – Give up for a new dream and take the grey elevator.

You can explore the area or just talk to the people in the area and then choose D Steal evil hearts to fix society and take the teal elevator.

On the next floor, you will realized that you can’t proceed. Crawl through the vent in the room and this will leads you to the Counselling Room.


Counselling Room

In the room above the Safe Room, you will find another TV but there is no video tape so you need to find one.

Go up the nearest stairs and find the room with a vent and crawl through it for the treasure chest with a good armor for your character. In this room, you can find the video tape too.

Go back to the room with TV and watch the video tape.

After watching the tape, proceed on north and you will encounter a mini boss. You have to fight it before you can access the security locked door. The mini boss has no weakness so aim for critical with one-shot kill for all an out attack.

Go through the security door by choose “By wishing to be that person” and take the elevator.


Twilight Corridor

This place is a huge maze puzzle which I find similar to Okumura spaceport. You can see there is a chart on color mixing result. You have to mix the right color to unlock the path. Use the map below to help you pass through this area.

  1. Purple Circled Console – Red and Blue On
  2. Red Circled Console – Red off
  3. Green Circled Console – Green On
  4. Optional: If you want to get the treasure chest at the lower platform marked with the Yellow Star, follow the Yellow line and switched the red console on and then off again when you head upwards again.
  5. Blue Circled Console – Blue off
  6. Pink Circled Console – Red on
  7. Orange Circled Console – Red and Blue on

Moving forward and you will enter the 2nd area of the Twilight Corridor. Similarly, follow my map to proceed. To help those who might have problem identifying the colors, I have included a number tag for each console.

  1. Green Circled Console (#1) – Green On
  2. Yellow Circled Console (#2) – Blue off and head back to get Treasure Chest
  3. Blue Circled Console (#3) – Red On
  4. Yellow Circled Console (#2) – Blue on
  5. Orange Circled Console (#4) – Green On
  6. Pink Circled Console (#5) – Green Off
  7. Red Circled Console (#6) – Red off

Your access to the Will Seed Room is now unlocked!

Now follow the below step to move on to the next area:

  1. Red Circled Console (#6) – Red on
  2. Pink Circled Console (#5) – Green on
  3. Orange Circled Console (#4) – Blue On
  4. Yellow Circled Console (#2) – Green on
  5. Blue Circled Console (#3) – Blue on
  6. Purple Circled Console (#7) – ALL on

Check the TV room next to the Safe room.

Choose “His persona fully awakened” and unlock the security door. You will be facing a strong shadow right past the door.


Psientific Model Eden

Your route to the treasure is now secured! Head back and wait for the promised date to send Calling Card.


Takuto Maruki & Azathoth

  • Maruki himself doesn’t have much power. This is a long battle but not a difficult one.
  • Maruki and Azathoth has no weaknesses.
  • Take note that the tentacles’ weaknesses change in different phase of the battle.
  • Tentacle of Protection
    • 1st weakness – weak to protection
    • 2nd weakness – weak to ice and frei
    • 3rd weakness – weak to bless

  • Tentacle of assistance
    • 1st weakness – weak to ice
    • 2nd weakness – weak to physical and psio
    • 3rd weakness – unknown
  • The best party member for me in this battle is Yusuke, Makoto and Haru. Each of the has the best support skills out of all the characters after their Second Awakening R. However those skills cost a bomb of SP. To avoid losing SP, pass the baton by targeting the weaknesses of the tentacles and make sure one of them get the 4th baton so that they can cast the support skill for 0 SP.
  • Azathoth will evolves once you deal enough damage to him and he will heal both Maruki and himself back to full HP.
  • Take note of the warning on the screen as some skills and actions are not allowed in different phase of the battle
  • Guard when Azathoth uses Tyrant Chaos.
  • Once Azathoth is taken down, the battle will end in the next turn against Maruki.

Just when you thought the battle is over, Maruki appears and evolve his Persona!


Takuto Maruki & Adam Kamon

  • First part of the battle is easy. Just keep hitting Maruki with your best attack.
  • When his hp is almost drained, he will offer himself to Adam Kamon.
  • This part of the battle is quite easy. Just keep yourself alive. None of the attack will work. Just increase your defense, lower his attack and guard.
  • The battle will end after a few turns when Futaba found his weakness.
