Ryō Naruse, who is an able attorney that can turn any case in his clients' favor, takes cases for the disadvantaged and defends them free of charge; therefore, he is called an "angel attorney." However, it is only superficial. His true self is that of a man who has sacrificed all his life to track down the murderer that killed his dearest younger brother 11 years ago—that is, he is "a cold-blooded revenge seeker, or the Devil King."
