Theodore Rasalgethi (スィーアッドー・ラサルゲスィ) is a character in the DXD: Legends of Tomorrow verse. He is the PE teacher working at the Rising Sun Academy; a school created to raise people capable of fighting the supernatural. He is well known for his excessive excitment and one of the reasons the school charges are so high since he tends to go overboard and cause about 40% of the damage that the school repairs every month.
