This guide intends to go through required choices to get every achievement and route ending.

Note that some choices are irrelevant for route/end selection, so feel free to experiment and come back here if you're stuck.

The novel can be divided in three arcs:

• DREAM, where your choices lead to one of the three heroines' routes (which you could read in any order, but this is the suggested one):
  
  • Misuzu
    
  • Kano
    
  • Minagi
• SUMMER, unlocked after getting all three heroine endings. No choices in this one.
  
• AIR, unlocked after reading SUMMER, will vary depending on your choices during your most recent Misuzu True End route.

Then there is Summer Sky chapter, which is a short story with no choices that happens before the events of the main game, and wasn't included in the original release. This one unlocks when you have finished the AIR route.

This is my first guide, so please let me know if anything isn't right or clear. Thank you!

I'll indicate the choices that lead to different routes. Use a different save slot for these so you can continue from that point to another ending.

After finishing AIR, you will unlock the First Sky Chapter. There are no choices here, either. Completing it will reward you with an achievement.

First Sky Chapter
Finished reading the First Sky Chapter.

If you followed the guide, you should have unlocked all soundtracks. From the main menu, visit MUSIC (scroll to the right) to earn the achievement.

MUSIC
Complete the soundtrack.

Visit the gallery (scroll to the right from the main menu) to unlock the achievement, given you managed to unlock all of the CGs (which should be the case if you followed the guide).

GALLERY
Complete the Gallery.

If you are missing the fourth CG from the second row in Misuzu's gallery, which is somewhat tricky to get, you need to go through the DREAM scenario again with some specific choices, reach the true end for Misuzu, and then start AIR, since the choices from the former will affect the outcomes for the latter. Breakdown below:

DREAM, July 19th:

• Try again
  
• Go back to the road
  
• Pester them
  
• The cabinets
  
• Give a serious answer
  
• Help out
  
• "He's real cute."
  
• Don't show them
  
• Ask for the story

Then meet the requirements to get Misuzu's True End, which you can find in previous sections of this guide. Make sure you reach the end and get the black screen saying "Clear data (system data) was saved."

AIR, July 20th:

• Go out for a walk
  
• Try going down the narrow road
  
• Fight
  
• Circle around

If you got all previous achievements, you should unlock this one automatically, too. Congratulations!
