Walkthrough (Main quest)
🕑 Added 2025-06-29 15:16:06 +0000 UTC7CP (Seven Corrupted Powers) - Main Quest Walkthrough
(Spoiler Warning: This guide contains only required content. Hidden elements are not included.)
1. Main Quest
(1) Basement Floor B10
Before entering B10, you can choose to either "Train black energy for one more day" or "Go out and explore." The former grants an attack bonus, but Zephyr will die.
If you revisit the empty prison cell where you obtained the "Old Rusty Scissors," you can also acquire the "Compression Bandage."
After rescuing Cain, talk to him and bring him to the crystal location for a stat bonus.
Cain Rescue: Cain tells you about the prison's alarm system. Go to the "Abandoned Prison" to get the scissors, revisit to get the bandage. Then go to the wire zone, inspect it, and use the scissors to cut the thread. Enter Cain’s prison, destroy the crystal, and use black energy to rescue him. (Note: Stimulating his genitals resets arousal. His weak points are armpits and head.)
Raymond Rescue: Just before rescue, use the scissors to disable the wire alarm near the exit. Stimulate him properly with black energy and cut the ropes within 4 turns.
Leonard Rescue: Visit his cell and use black energy to rescue him. Then revisit the protagonist’s original cell, grab the monster’s horn, and return to Leonard’s cell.
Zephyr Rescue: Choose "Look for a way out immediately" at the beginning. (Waiting one more day will result in Zephyr’s death.) At his cell, choose: Peek inside, Keep watching, Still watching, Wait and come back with strength. After obtaining black energy, return when the message "I should go back and heal him" appears. Then use black energy to heal him. During the boss fight at the escape route, choose Throw myself forward when the prompt appears to save Zephyr.
(2) Basement Floor B9
After defeating the glowing firefly in the lower-left room, use the mysterious key to open the wooden door in the top-right and obtain (Magic Crystal, Worn Blanket, Dildo).
Defeat all four monsters to collect all four keys and proceed to the next dungeon. (Note: Spamming arrow keys may skip monster encounters.)
Warren Rescue (Preparation): First encounter: Ask what's going on → Stay by his side for a while, then fight the monster. (Bandage is used automatically if you have it.)
Arthur Rescue (Preparation): You must obtain the items (Magic Crystal, Worn Blanket, Dildo) from the wooden door. Then trigger Arthur’s event in the second map. Hide in Shelter 1 or 2, then attempt the rescue. Use the magic crystal. (If you abandon the rescue, you can still save Arthur, but incur +30 corruption.)
Warren/Arthur Rescue (Milking Room): In the third map, release their genital bindings. Then adjust stimulation to raise both to 100 arousal simultaneously. (Requires the dildo. If the protagonist’s lust is too high, judgment fails, limiting attempts to 5, making simultaneous rescue impossible.)
Use the color-coded hints to pull four levers in the right order to access the right section. Defeat the floor boss to reach B8.
(3) Basement Floor B8
Tristan Rescue: Depends on action count. Talking to Dante or the old man costs 10 points each.
Go to the center of the map to spot Tristan (can view twice). Report this to Dante.
Return with Dante to check again. On the way, loop down and find a button at 6 o’clock position to gather mosquitoes in one place.
Talk to the old man to learn about defeating mosquitoes, then again to receive a quest to gather 10 mosquito oils.
Bring back 10 oils to get a bomb. Use it to eliminate the mosquitoes. (No more random mosquito mobs appear after this)
Defeat the mosquito queen. If successful within the action count, Tristan joins. If not, both Tristan and Dante are lost.
(4) Basement Floor B8-2
At the path leading to B7, you'll find a fork: left and right.
Left Path: Triggers Iman’s rescue route. To activate it, you must:
Complete Arthur’s Day 1 free action
Obtain "Someone’s Ring" from “Adventure - B9” before proceeding
If both are completed, Arthur will recognize the ring and sense Iman’s presence on the left path. He will guide you through the fog maze (which otherwise lacks visible mapping).
If you fail to reach in time, Arthur disappears, and Iman cannot be rescued. However, even without the ring, if the player reaches the end by intuition, the quest proceeds normally.
Iman Rescue: Defeat the tentacle monster (3 phases). It raises lust and damages allies. Use Shelter Facilities to boost stats and reduce lust beforehand.
(5) Basement Floor B7
In the scouting phase, choose one companion: Iman, Dante, or Tristan. You will fight a mysterious blue-haired man.
In the following mini-map, you will rescue Ethan no matter what.
Then B7 begins. Yellow dots mark possible exits—only one is correct. The exit changes randomly each run. If unlucky, retry for closer exit.
Each movement has a 7% chance to trigger random encounters. To skip them, spam arrow keys—but beware of missing events.
B7 includes HP recovery, lust reduction, forced movement, random CGs, crafting formulas, etc. You can escape immediately or explore more—but each move increases the action count, which affects Victor’s rescue.
The floor boss has 4000 HP, but if you clear the tentacle room on the map, its HP is reduced to 800. Additionally, if you use a bomb found in the map, its HP is reduced by another 400.
Defeat the boss to find a man covered in tentacles. Use accumulated count to reduce to zero via minigame. Tap indicated body parts to remove tentacles. The more attempts, the shorter the time.
Left/Right is based on the character’s perspective, not yours.
Beware of the "Mysterious Tentacle". If encountered repeatedly, its level rises and will eventually trigger an unwinnable battle. Exiting to "Resupply" resets its level to 1.
(6) Post-B7 Content
After clearing B7’s boss and completing Victor’s tentacle event (success/fail), the next sequence unfolds.
If you've progressed a character’s romance route far enough, you’ll unlock a special spicy event.
If on a corruption route, the protagonist proceeds alone—so for your first playthrough, completing a pure romance route is recommended.
Applicable characters: Raymond, Cain, Leonard, Zephyr, Warren, Arthur, Tristan, Dante, Iman

Maybe separate, don't have a plan for now. Guides will not be provided until a week after release

Question, will this be updated or the next floors will be in a separate post?

If all the tiles look like they’re the same color, please check whether your browser is in dark mode or if you’re using any extensions that affect page colors. If the page size is too large, the grid may shift, in which case reducing the font size could help. If neither of these is the issue, it would be helpful if you could explain how the map looks different on your screen.

I’ll make sure to add a warning message and a save prompt before entering the 7th floor minigame! Thank you so much for the suggestion! 😊

Absolutely love everything about the game! I do think the time limit when trying to save the guy after b7 might be a bit much, or at least on the strict side. I kept seeing "failed, tentacle gains hp" or something but I didn't have time to even think about what I should do, even with the helpful guide telling me. I kept clicking on the tentacles but I kept seeing red text with the clock ticking down causing a lot of panic clicks.

Are you referring to the Seven Corrupted Power room on B8? If you’ve already cleared the main quest on the 8th floor, you can access it by heading to the place where the Mosquito Queen was during your exploration of that floor. Unfortunately, there aren’t many related CGs available yet.

How can I further explore the seven corruption power rooms on B7? What requirements must be met? I'm very interested in unlocking more erotic CG scenes.
