Basara Toujou has a hard life. He is the older step-brother to two demonic sisters, Mio and Maria Naruse, whom he protects from entitled demons looking to claim Mio's power for themselves. On top of that, rising political tension within the demon realm only makes his job more difficult.

Now on the enemy's turf, Basara will have to grow stronger through erotic pleasure in order to do the impossible and protect everyone.
