Sister Other Paranoia – All endings and all CGs

By Editorial / August 16, 2026 / Guide / 3 minutes of reading

In Sister Other Paranoia, I explain different routes to unlock the endings and all 25 CGs in the gallery. In this guide, I show how I unlock the Normal, True, Monkey Happy, and Caterpillar Bad endings, along with the CGs tied to each route.

How to Unlock All Endings and CGs in Sister Other Paranoia

Below, I explain how I unlock each ending and CG. I recommend getting all of the CGs after completing the True ending, since a lot of the CGs are tied to specific endings. For clarity, the CGs are numbered like so:

Normal Ending

To get the Normal ending, I complete each of the 5 routes I can choose from in the lighthouse scene. I can complete them in pretty much any order, except for one special case that I cover in the Monkey Happy Ending.

Unlockable CGs

  • 1 – Complete the prologue.
  • 7, 8, 9 – Complete the Fox route.
  • 10, 11, 12 – Complete the Monkey route. Unless I’m on the path to the Monkey Happy Ending, I won’t be able to select the “He’s not a bad guy” choice.
  • 14, 15 – Complete the Caterpillar route. To complete the route and get the normal end, I select “You can do it. You can fly.”
  • 16, 17, 18 – Complete the Bat route.
  • 19, 20 – Complete the Ring route.
  • 2 – Complete any of the routes.
  • 6 – Get the Normal ending.

True Ending

To get the True ending, I first need to complete the Normal ending. After that, I click on Sahana on the title screen. I hear a ding, and my cursor turns into a crescent moon when I hover over her.

Unlockable CGs

  • 3, 4 – Progress normally.
  • 5 – In the sunflower field, when I’m given the option to peer into her mind, I wait for a little bit until the option “Trust my little sister.” appears. Afterwards, I get the True ending.

Monkey Happy Ending

To get the Monkey Happy Ending, I select only the Monkey option on the lighthouse screen. I can then choose the “He’s not a bad guy” option and get the yaoi ending.

Unlockable CGs

  • 13

Caterpillar Bad Ending

To get the Caterpillar Bad Ending, I talk to Igusa on the rooftop and choose any option other than “You can do it. You can fly.”

There are no unlockable CGs for this ending.

CGs 21 – 25

I should be able to get most of these by completing the Normal ending. I randomly get one of them after completing any of the route segments. If I’m missing some, I save right after the cutscene with Sahana, when I get some dialogue from her in the centre of the screen with no sprite and a black background. I can then keep reloading that save until I get the CG I need.
