Grand + True End Focused, NON-Spoiler Guide

If you want a full heavily detailed guide, here's one by the translator of THE SHELL series:
https://docs.google.com/document/d/e/2PACX-1vRSRxLg4crk9sEBFCK3lgxwNMRkRPs8gZuBxxOqUr6R6aB4PEWMRAN3Af_uQBVOg5YRjRA19qrkG-MV/pub

However, I wanted to make a spoiler-free version that only covers the necessary choices, removes names that would spoil things, avoids bad endings.

The Shell/Kara no Shoujo 3 Actually has NO H-Scenes at all. Any 18+ content are related to relevant corpses a few quick story-important CGs, and some quick R-Rated Sex Scene style scenes you are required to see on a second readthrough and beyond.

Crime Investigation scenes are as streamlined as The Shell/Kara no Shoujo 2. (you always Investigation everything that lights up cursor once, then click End Investigation)

Every single map slice of life choice is all up to you, as they do not matter for getting any endings. I will mark these as "Your Choice".

Normal Ending 1 (REQUIRED to unlock Grand Ending)

As said in the header, the only "good" ending you can get is Normal Ending 1 on a first read-through. However, it's still possible to get bad endings on a first read-through so make sure to pay attention to this guide closely.

Grand Ending (unlocked after Normal Ending 1, REQUIRED to unlock True Ending)

Almost all the choices to get the required Normal Ending are the same as getting the Grand Ending (NOT the True Final ending). On a second read-through there's a only a handful of different options and new choices to make so make sure to pay attention.

There will also be a lot of brand new scenes, so don't expect this to be an easy skip to the end readthrough. Also this playthrough is where you'll see the closest thing to H-scenes. They are plot required, but treated more like short R-rated Movie Sex scenes.

True Ending (unlocked after Grand Ending)

On a third read-through there's newly updated scenes that show up after the timeskip ONLY. There is NO new scenes in the first part of the game.

If you don't care about these updated scenes during timeskip (Just added voice acting + a few CGs to previously unvoiced scenes), you can load the save I requested you to make in Grand Ending.

• LOAD Save from Grand Ending to get to True Ending Faster
  
• Otherwise, click "New Game" and follow Grand Ending walkthrough up until new choice on 2/27
  
• 2/27 Grin and Bear, Stop
  
• If you got to this point, you got the True Ending
  
• However, I HIGHLY recommend also getting the other major ending by making the final choice "Let Him" for more KnS2 Closure
