Walkthrough
  1. 1

    Go down the stairs. Exploration of this floor is optional for an achievement.
  3. 3

  11. 11
    Continue to a terminal, save, and go up the stairs to Eridanus 2F.

  20. 20
    Use the portal in the southwest to continue south.

  22. 22
    Take the stairs up and use the portal to create a shortcut to Zelenin's area.
  23. 23
    Go to Zelenin, which activates a teleport to a new area.
  24. 24
    Return to the area south of the teleport device and take the stairs up.
  25. 25
    Ame no Uzume will give you the EX Mission: Marebito, the foreign god.
  26. 26
    Find a shortcut back to the heal and save area.
  27. 27
    Take the stairs north of where you met Zelenin, past the opened shortcut, to reach another shortcut to the heal/save area.

    Go back past the teleport device Zelenin activated.

    Use the Heal Spot on Eridanus 3F.

    In the west, challenge Zouchouten in a battle with specific rules for an EX Mission: The ever-steeper trial I. Defeating him unlocks him for fusion and grants Sub App items.
  34. 34
    In the east, challenge Kazfiel in a battle with specific rules for an EX Mission: Before the holy battle I. Defeating him unlocks him for fusion and grants Sub App items.
  35. 35
    Secret doors in these rooms require higher rank Unlock and Gate Search Main Apps to open for future challenges.
  36. 36
    Use the elevator in the south to reach Eridanus TOP.
  37. 37
    To the west on Eridanus TOP, find a hidden gate portal leading to a terminal and heal spot.
  38. 38
    A powerful demon is detected to the north. Approaching it triggers a scene ordering you back to the Red Sprite. You cannot progress further due to Gate Search limitations.

    Look for a hidden door on the west wall near the terminal.
  43. 43
    Inside, find more portals on the west wall. Trigger a scene behind one of the doors, which adds the main mission: Jack's Bargain.
  44. 44
    During the scene, you will face an alignment question: "Can we establish cordial relations?" Choose between Humans should help each other (Neutral), I'd sooner trust the demons (Chaos), or I don't trust anyone easily (Law).

    Explore the remaining areas to find [Muscle Drink x3] and [Vi Incense x1].

  49. 49
