Sorry, we won't have the new sizes for this coming update, but we are working in the background to have size 5 ready for future updates. I can tell you the size jump from 4 to 5 is surprisingly big. The main author for Honoka's route has had to prioritize his job more this past update cycle, but as we draw closer to finishing other routes more help can be allocated to finishing her route as well. We appreciate your patience throughout the ongoing work on the game.
