Mamoru Aikawa is a God Candidate and a major antagonist of Tenkuu Shinpan. As he witnessed his father's suicide as a young child, for which his father wrote a note to "those who betrayed him" on his business and social ventures, Mamoru grew to despise those who were betrayed, believing them to be a cancer to society and worthy of suicide. He explains this belief to Rika and anyone who will listen, with his doctrine explained as: those who earn betrayal earn death.
