@Kanami-chan Your typical video game character called Akira tries to rid an island of a vampire overlord (Miyabi) that keeps spreading his diseased blood around to infect other victims. The vampire overlord became as powerful only after the Japanese experimented on him during WW2 and killed most of his family (that he hated). He loathes humans, so he has a plan to turn everyone into vampires through infected mosquitoes. Meanwhile Akira's life goal is to kill all
titans vampires, most importantly Miyabi.
There are obviously a lot of things missing in the above summary.
