|“||A demon with the ability to reflect like light.||„|
|~ In-game description|
Bathin keeps watch over the castle's mechanical library (Defiler of Taboos) and is encountered when the party reaches the end of the stage. He uses extreme speed and electricity to attack anyone that hasn't gotten out of the way on time. Bathin's desperation attack, Grand Cross, ultimately kills him by causing him to accelerate to the point where he collides with his future self.
Bathin can be found in the Underground Sorcery Lab in a humongous room. There, he uses a series of reflective pads to bounce off of using his paranormal powers. However, the patterns of his attack are predictable, allowing Miriam to hide beneath him when he uses Reflector Ray.
