The protagonist Nano, a female vampire, got struck a deep wound by the female hero Olivia. She managed to run away, but thought for sure she was dead, after living 500 years without knowing love.

However, St. Gia appeared before her and gave her her own blood. They spontaneously fell for each other. Since they were both female and Nano was a vampire, however, such a forbidden love could not be allowed to surface. Because of that they continued their strange relationship as friends.

One day, Gia talked to Olivia about Nano. Olivia felt her trust betrayed. She branded Gia as a heretic and had her imprisoned.

Nano found out about it and went to rescue Gia. However Gia was already dirtied by multiple guys. Unable to stand it all, Gia killed herself.

"If I'm reborn again, I want to live happily with you. Forever." -Gia's dying breath

Nano heavily grieved at Gia's death and started to hate the current world where homosexual love is prohibited. She magnificently embraced Gia and wished she had the courage to always stay at her side.

Drowned in sorrow, Nano remembered that the "Orb of Soulscream" can be used to revive a person. She decided to obtain it at any cost.

However, Olivia foresaw Nano plan, and snatched and hid Gia's soul.
Furthermore, Olivia was already in possession of the orb.

To find out where Olivia hid the orb, Nano decided to secretly kidnap and interrogate the royalty of various nations...
