What is the relationship between Shuichi Akai and GIN? The answer is simple.
GIN is the gold medal killer of the black organization, and Shuichi Akai is the FBI's ace agent.
Shuichi Akai is an undercover agent who has penetrated into the organization. GIN is his partner, in name only.
He is beautiful, cool, and mellow RYE. He is indifferent, aloof, and full of GIN.
They have so much in common. The same aloofness, the same cleverness, the same perfection.
They are so different. GIN kills people, Shuichi also kills people, but he is named as justice, that's all.
Akai Shuichi's code name is RYE, and his pseudonym is Morohoshidai. GIN called him, Ah Yi. Ah Yi.
GIN is GIN, no one knows his name. Xiuyi called him Silver. (The Roman pronunciation of GIN.)
He is his perfect partner and his greatest enemy. One of them is pure darkness, and the other is light that sneaks into the darkness. Either he devours him, or he drowns him.
From this point of view, they are just similar enemies.
But what if he said that he loved him.
