Additional Credit

The original guide was found here:

Since since I couldn't find any guides for this game here on Steam I wanted to add one. Full credit goes to SeniorBlitz. I just slightly modified the guide.

I think this guide is a little overblown or at the very least, not very well worded.

There are two points in the VN that have you make choices:

First choice screen (save here after reaching this point first time):

1. Follow Calen (Calen Route)
2. Go With Mari (Mari Route)
3. Call up Aoi (Aoi/Lycoris Route)

Second Choice screen (save here after reaching this point first time, only available after selection of Aoi/Lycoris Route):

1. Get Iris’ help (Aoi Route)
2. Manage on our own (Lycoris Route)

You can choose routes out of the first 3 choices in any order and you get all the CGs after making these choices one after another (no recovery necessary), the extra CGs you can unlock in the Extras menu.
