That wouldn't really fit either character in this gag story. Haru's character is that she is naive to everything and Eury is the eternal virgin straight-man to the hijinks.

3. Imp-kun must stay a man-of-culture
But I wouldn't have minded Shigure joining the offline hookups regularly. Although that would likely be asking for too much. This manga is too vanilla despite all the weird stuff it is pulling
