I purchased this piece on Steam, but was unable to unlock the first gallery of the character. Can I download the strategy? Can you post a guide on Steam Community?
Here is a route guide for the good endings! To unlock the first CG for Artie and Moira, you just need to talk to them after capturing Kasanov in the beginning of the game! To unlock Claudin's CG, you need to walk with him, tell Kasanov he is bold, and then punch him.
