From Izumo no Ryuu:

Note: Contains nudity and gore warning.
From Evil Empire:
Escaping from a brother who had just ascended the throne, Yoshitsune, along with his servant, comes across a house in the middle of a desolate mountain. Oddly enough, only a young woman lives there, who seems to possess a very dark and ominous past.
This long over 1000 years journey focuses on our main protagonist Kurou. This may be a tad bit confusing at the beginning, but once you understand the plot this story can be quite entertaining, but the main story goes as such: It starts with out with Kurou meeting the beautiful women by the name of Kuromitsu, thus began a relationship which transcends life and memories. A journey of immortals and those who chase after it. The majority of this story takes place a few centuries into the future where Kurou is separated from Kuromitsu and without memories and he then searches for answers to who is and why he does not die and who was the women he is so transfixed upon.
