Fun fact the first two doujins have slight redraws from the author compared to the digital version.

First one is about Sumire getting raped by the Hive of Darkness

Second one is Sumire during Shin Sakura Wars being used to pleasure all sorts of people to keep the Imperial Theater afloat.

Third one is Sumire x Ogami all the way through. First part with her older design and second part with her Shin Sakura design and some extras.
