Everything Ends In 0: Everything Ends In 0 Achievement Guide

One achievement is unlocked by completing the game and getting to the credits. Every other achievement requires you to read through all of the dialogue of a character each.
To read through all of the dialogue and thus obtain all achievements you will need multiple playthroughs. Completing the game the first time takes the central one hour and a few more minutes to go through the credits and addendum.
You will need multiple playthroughs to go through all the dialogues and obtain all achievements. However you can skip the ending in consecutive playthroughs simply by closing and reopening the game, which I recommend after having seen it once.
