What is the main content of the anime Yue Yong? Is it very touching? ?

Photographer Moriqi Kohei, who can only take supernatural photos, came to an ancient castle in Germany to collect materials. He met the vampire girl Hazuki, who was imprisoned in the city. He sucked Kohei's blood and thought... He escaped from the city as a "servant", but it had no effect on Gengping. Later, Kohei unknowingly destroyed the sealing device in the city, and successfully escaped from the city with Hazuki, and came to Japan in order to find his mother's whereabouts.

After arriving in Japan, Hazuki came to the home where Kohei lived with his grandfather, and lived with them unreasonably. Kohei, who also lost his mother since childhood, saw the overlap between Hazuki and himself, and decided to protect Hazuki as a protector and search for his mother together.

At this time, a vampire girl named Elfrid and the vampire Count Kinkel appeared and wanted to bring Ye Yue back to the castle.

Where is your mother? The fate of Hazuki and Kohei?
