The following are the flowcharts from the Official English Edition of the game here on Steam, made by the creator of the Ultimate Edition's flowchart. They are be uploaded here separately as an alternative to the Ultimate Edition Flowcharts which use Mirror Moon's... flawed... Fan Translation. I chose not to replace the Ultimate Edition Flowchart as unlike it, this version does not feature the Routes to the Hentai Scenes, as the Steam version does not contain them.

Credit, Thanks and Questions should be directed to the original creator of these Flowcharts Poki#3. I'm only acting as a middle man for them, as they are currently unable to post it themselves. You can find the uploads to his flowcharts for the official English release on his Google Drive, which he asked me to link to. They include a unified flow chart of all the routes that I am unfortunately unable to post here due to file size liimitations.

This is the flowchart for the start of the game. It covers the first three days, and leads into the other three routes: Fate, Unlimited Blade Works (UBW), & Heaven's Feel (HF). The game forces the player to go through the routes in a specific order. If it is your first time playing through the game you will be railroaded into the Fate Route. You cannot access Unlimited Blade Works until you complete Fate. You cannot access Heaven's Feel until you've completed both Fate & Unlimited Blade Works. However you can still access any route you have already completed from here.

FIRST THREE DAYS

This is the Flow Chart for the Fate Route. If it is your first playthrough, you will be railroaded into this route. This route must be completed before you can access Unlimited Blade Works.

FATE

This is the flowchart for Blade Works. If you have completed the Fate Route, this route will be unlocked and can be (accessed along side Fate) by choosing "Stop Her" on the third day.

UNLIMITED BLADE WORKS

This is the flowchart for Heaven's Feel. If you have completed both the Fate and Unlimited Blade Works Routes, Heaven's Feel can be accessed by prioritizing Sakura whenever given the choice in the first three days.
