3rd Opening Credits
The animation director, Naoyoshi Shiotani has stated that "In the bath scene, I tried to hint that Saya and Diva's relationship could have been completely the opposite. Although you can't see now after the processing stages, Diva is looking at Saya, but Saya is not looking at Diva. And at the end, you see a contrast between Saya, the older sister, and Diva, the innocent little sister."
