Can I suggest something involving the status screen during the playthrough? I noticed that the more Syahata gets caught or finished she gets more lewd.
I would love to see different animations the more her status changes throughout the playthrough. Like when surrendering to the enemy? Instead of just lifting her skirt or raising her hands, she also lifts her school uniform to flash her breast. Heck. Even in the masturbating animation, her panties sliding down her legs and teasing her breast would be lovely to watch.
