Sanemi is a vampire who slays vampires? None of the other hashiras know, he has been good at hiding it. Vampires were okay by society, as long as they used donated blood bags. Or if they had a person who lent them there blood. Sanemi can't keep his secret, a secret forever... some characters do NOT belong to me, but to the creator of the anime Demon Slayer.
