Johannes (ヨハネス Yohanesu?) (pronounced 'yo-HAH-nis') is a character in Bloodstained: Ritual of the Night. He is the last alchemist in the world.
A member of the defunct Alchemist guild and Gebel’s best friend. Johannes was the only Alchemist who dissented with the plan to call demons to the earth to cement Alchemy as the prevalent philosophy. His rejection of the other Alchemists’ scheme is what kept him from sharing their fate. He has a vague understanding that Miriam’s awakening and the demon castle’s appearance are no mere coincidence.
