Dance in the Vampire Bund II. Scarlet order - Nozomu Tamaki

BLOOD STONE
As Mina and Akira continue digging deeper into the case of the mysterious vampire attacks, they discover a tale of enduring love and twisted ambition that spans one hundred and seventy years. Meanwhile, Yuki finds an ancient vampire known as Saburo, the self-appointed guardian of the hidden ruins beneath Mt. Fuji and the bearer of a blood-red gem that quenches the thirst of any vampire near it-the akamitama. As Mina seeks to reunite long-lost lovers, she must recover the treasure so desperately sought by Telomere's leader and her own doppleganger before it's too late.
