You can build your own dialogs with the charcters of Our Red String visual novel with this tool. Select the background, add 1 to 5 characters, position them in the screen, flip then side-to-side, choose their facial expression, which clothes they wear, add some ornaments and insert your dialogs. Then take a screen shot and share it :)
I'm always adding new features and new characters when they are added to the game. Feel free to send me your feedback and questions/suggestions.
Enjoy!
