戦国の黒百合 ～ふたなり姫と敵国の姫君～

Continuing from the previous instalment, Princess Oda Saku of Owari Province continues her struggle to take control of her own future in a time where women are afforded little to no political power.  Amidst the political intrigue, plots, and betrayal, another princess is added to the mix as Owari formally receives and welcomes a noble lady from an enemy nation for diplomatic reasons.

As the head of the Oda Clan and Saku's elder brother, Nobunaga entrusts this princess, Fuki, to Saku's care.  With a bit of investigation, the shrewd and calculating Saku realises Fuki has been abandoned to Owari, and that no one will miss or care whatever may happen to her despite her status as a princess.  At the same time, Saku finds out her brother has been secretly making preparations behind her back to welcome his beloved concubine, Kitsuno, back into the castle.  Though Kitsuno comes from a humble background and has always been in poor health, Saku immediately realises the threat that Kitsuno poses to her power, as both Nobunaga's clear favourite, and as the mother of Nobunaga's eldest son -- and thus the mother of the clan's future successor.

In anger, and in knowing there was little she could do to prevent Kitsuno's arrival, Saku leaves her home to stay with Fuki, under the pretense that she is providing compansionship the princess entrusted to her care.  Instead, she appeases the darkness and sadistic lust inside her by violating Fuki repeatedly, considering her little more than a 'toy' that exists solely for her entertainment.  

The second part of the story tells of Saku's continued attempts to secure her power, only to find it weakened even further as someone discovers her secret...
