Rin Ishikawa, 19 years old, is a professional boxer competing in his first world title match. A man who has no doubts about his own talent. What's more, he is a man who has even been given a talent from heaven. “Genius” is something fierce and ephemeral. "Talent" is something that can be destroyed in an instant even after years of training. "Pugilism'' means eating each other's flesh.
