[Heiqing Langjun] Eisei no Gou (Towako 7) [Shiromaru]

The last survivor of a massacred family of imperial alchemists, this young girl is anything but helpless—she's a humanoid Tai Sui, the legendary 'fruit of legend' whose flesh grants immortality to whoever consumes it. Desperate and alone, she offers herself up to be devoured rather than be caught by those hunting her, but her sharp teeth and thirst for blood turn the encounter into something far more carnal than either expected. Just when she thinks she's found purpose gathering herbs to cure her master Zongyi, hunters armed with gunpowder close in to capture the little monster for their own ambitions.
