After the isekai elevator traps Ota in the third chapter’s escape room in No Sleep for Kaname Date as your group accidentally completes the ritual, you’ll need to work as Iris and Moma to free him from the trap before it’s too late for him.
You’ll need to work out the entrry code to the rocket ship on Iris’ level, then ascertain which Iris is the real girl when you subsequently take control of Moma in this escape room section of No Sleep for Kaname Date. Use the hints on Iris’ level of the escape room to work through clues.
How To Enter The Rocket Ship
After you’ve placed the last button into the missing slots in the elevator panel as Ota, the trap is complete – this is an isekai elevator that’ll take Ota to another world, and you’ve accidentally completed the code needed to send it off by slotting and pressing each of the buttons!
To save Ota from this fate, you’ll be directed to a locked rocket ship in the corner of Iris’ level of the escape game, in the back left corner by the sky screen you used to deduce the constellations in the first part of the puzzle. The ship requires a six-letter code to enter.

You’ll need to head over to the green planet display on Iris’ floor, where you’ll notice a tiny hole in the top. You’ve got a needle from one of the earlier sections, so recall that you used a paper cup and a needle to play a record during your dive into Pewter’s Somnium just before this – time to use this method again.
The only thing is, Iris has the needle, while Moma has a paper cup left from when he used the vending machine to detach the sticker from the card earlier in this chapter. He’s on another floor of the puzzle, though, so you’ll need to get creative in getting the cup to Iris.
Recall that you sent items between Ota and Iris while the elevator was showing the green warp portal – red can send things to green, but blue can send things to red. You’ll notice that Moma has a blue portal on his floor, while Iris has a red portal, so as Moma, throw the cup into the blue portal to send it down to Iris.
Once you’ve grabbed the cup while playing as Iris, use the combination mode in your inventory to combine the cup and needle, then return to the green planet display and interact with the top of the case. Now, you’ll have the option to lower the needle into the display to hear a broadcast from the planet.
It’s giving you the code for the rocket ship: MUNDUS. Return to the locked ship as Iris and enter the code, then get into the rocket ship.
Which Iris Is Real?
After Iris gets into the rocket ship, it will move to another level of the area, and your control will be switched to Moma as he watches five rocket ships with an image of Iris on their doors descend from the ceiling on his level, weaved in between the moons where you shot the lizard moon in the eye earlier in the puzzle.
Moma is instructed to shoot every Iris that isn’t real to save the real one from danger, so to begin, you’ll want to get behind the gun and aim at the sky. Observe the images of the girls on the doors and shoot down the three obvious fakes: the Iris all the way to the left, the one in the center, and the one all the way to the right.
The second and fourth Iris images are identical, though, and Moma will have a hard time figuring out which one is the actual Iris. To solve his conundrum, you’ll want to switch control to iris yourself and take another look around the rocket ship you’re in.
Look through the window on Iris’ ship, where you’ll see the lizard moon to Iris’ right. Switch back to Moma, and using this knowledge of what the real Iris can see, shoot the right Iris down. However, this doesn’t end the puzzle – the Iris you left alive is still hanging from the ceiling, which trigger’s Moma’s Third Eye conundrum for this puzzle.
Iris mentions that she sees a “beautiful moon” out the window, but Moma remembers he shot the eye on the lizard moon earlier and deduces that Iris isn’t actually in that rocket ship either. Shoot the remaining ship to complete the puzzle.
