This is a complete walkthrough of every ending in School Days REMASTERED.
Most School Days guides online were written for the HQ edition or older releases. Following them in the remaster, I could never get the routes I wanted. So I reverse-engineered the game itself, pulled out every affection value and every branch condition, and replayed each route through the game's own branching code to check it. This guide is built on that: the choices for all 22 endings, how each choice changes Sekai's and Kotonoha's affection, the condition at every branch, and a save order for collecting every ending in one sitting.
If you find a mistake, contact me on X or GitHub at the bottom of the page.
