Summer 1980 Anime

In contemporary Boston, Dracula gatecrashes a Satanic ritual and makes off with the intended sacrifice, Delores. Overcome with love for her, he's unable to drink her blood and instead settles down with her and fathers a child, Janus. But Dracula's enemies are massing against him—a team of vampire hunters, including the wheelchair-bound Hans Harker, crossbow wielding and new recruit Frank Drake, a descendant of Dracula, are closing in. And Dracula has been stripped of his vampire powers by Satan and he desperately needs another vampire to restore his powers so that he can both see off his pursuers and avenge the death of Janus at the hands of vengeful Satanists.

Nuclear testing has resulted in the abrupt evolution of the Fumoon, a tiny but highly intelligent humanoid race on a small island, who are detected by Dr. Yamadano. Except for a few witnesses including the detective Shinsaku Ban, and the young men Rock and Kenichi and Kenichi’s sister Pichi (Pinoko), no one believes him. The Fumoon are kidnapping animals from around the world to bring with them as they use their space ships to evacuate the earth, because they know Earth is shortly to be destroyed by an enveloping cloud of black gas created by a stellar explosion. The Fumoon intend to abandon mankind, but one Fumoon, Rokoko, who becomes good friends with Kenichi, tries to help Dr. Yamadano and the others to develop a space ship to allow a few humans to escape, with the help of Dr. Ochanomizu and Dr. Frankenstein.
