Makoto Isshiki is a Mulian who works for TERRA. He is a clone sharing the DNA of Ernst von Baumlhbem. He has an inferiority complex which stems from being a Dranked Mulian as a child when he was staying at the Bahbem Institute. He had abilities beyond what was expected of a D type but he failed to recognize praise from others and let the quotDquot rating stop him. Because of this he feels that he has to constantly prove himself. He also has an extremely haughty and arrogant attitude and is contemptuous and dismissive of Ayato.
