Hello Charlotte: Childhood's End — Spoiler-Free Achievement Guide

Everything you need to do in order to 100% this game, without any spoilers. No Charlottes were harmed in the making of this guide.

*＊✿❀ INTRODUCTION

Hello, world! With this guide i'll show you how to get every single achievement in Hello Charlotte: Childhood's End. I've categorized them by whether they're missable or not, and within each category I've put them in chronological order (or at least the order in which I got them), so as long as you follow along you won't miss a thing.

Although you won't need to open a single spoiler tag to read this guide, there were a few places I decided to put some details for clarification. They don't reveal anything too plot-specific, but I decided to tag them for people who prefer to go in completely blind.

If you've already completed this game, you're going to have to delete some files to be able to play again. For me, they were located in This PC -> Local Disk (C:) -> Program Files (x84) -> Steam -> steamapps -> common -> HC3. Said files are the .rvdata2 ones (Global + Save Files).

⋆ ˚｡⋆୨୧˚ MISSABLE ACHIEVEMENTS

  Ether Solutions Has a Solution For You
  Watched all the TV Commercials. 

You won't get this achievement right away, but by doing something on Day 1 you'll be able to get it later. Go to the TV room and click on the middle of the TVs, where a remote is. You'll watch a commercial for Linq, which is one of the commercials you'll need for this achievement. Don't worry, the others are unmissable.

  Monster
  "You don't wanna play, I destroy your research." 

On Day 2, go to Felix's lab and interact with the computer. Press 'Destroy it'.

  No Fun Allowed
  Broke all the TVs AND the microwave. 

After doing the above, go to the TV Room. You will be presented with a choice. Press 'Yes'.

  Bully
  Pushed Anri into the pond. Well, aren't you proud of yourself now? 

This also happens on Day 2. At school, after Anri buys Charlotte chips, go to the garden. Interact with the spot on the screenshot below. Press 'Push Anri in'.

  Thief
  Stole Anri's money. You really needed that gacha money, huh? 

When you find yourself in Anri's room, interact with the wardrobe. Press 'Yes'.

  Linq Enthusiast
  Tried to use Linq on C.

On Day 3 of the False Realm, at school, after you talk to C in the library, you can go to the rooftop. There a boy will give you Linq. After wandering around for a bit and interacting with students, most of which will tell you something about Linq, you can head into the Infirmary. Press 'Use Linq on Charles'.

  Q84 Enthusiast
  Chose Q84 over your Charlotte.

After finishing Episode 0, you will be presented with a choice. You need to pick Q84 in order to get this achievement.

  Brainiac or Just a Cheater?
  Completed the puzzle without using the memo.

  I Can Handle It, Mr. Honikker
  Didn't use Honikkerpedia even once.

Both of these work in the same way - you need to complete the puzzles (on 4F and 9F) without selecting the memo/honikkerpedia from your inventory. Here's a guide that has the solutions to every puzzle in the game:

⭒❃.✮:▹UNMISSABLE ACHIEVEMENTS + ENDINGS

There's pretty much no way you won't get any of these (unless your game glitches), but I thought they should have their own section so players will know which achievements they won't have to worry for.

 
  Survivor
  Successfully escaped the inevitable death by the hands of 1F tenants. 

Here's what to do if you're struggling - Go to the upper room and move the crate between the lockers and the mop. Climb up to the vent. You have 9 seconds to escape - go straight ahead, and don't forget to press the Shift key to run. Hide in the Charlotte pile. When asked to wait a little, press 'Yes', then during the next choice select 'Let's go'. Exit Huxley's Room from the door. Then go to the elevator, the same one that takes you to school.

  See You in My Heavenly Kingdom
  Completed all the scenes in True Realm.

 
  Disposable Soul
  Completed EP0.

  Childhood's End
  Acquired your one and only Happy Ending.

  Goodbye, Charlotte
  Acquired both the True Ending and True Freedom.

You should make a note of keeping a save before the ending choice, since they can't both be done in one playthrough
