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.
