GIN's Other Self Is a Pretty Boy

The main story is told from the perspective of eighteen-year-old GIN from a parallel world.

During a mission, Gin found a pretty little thing who looked exactly like him, but had a completely different air about him.

The pretty boy claimed to be Gin's eighteen-year-old twin brother from a parallel world. Curled up inside an iron cage, he shuddered at the sound of footsteps.

He looked up, revealing limpid, lake-green eyes. His voice was soft and sweet, softer than fluffy cotton candy.

"Big brother, are you here to get me out?"

The pretty boy was both domineering and spoiled. He liked slipping his hands behind Gin's neck to warm them, and when Gin glared at him, he'd make a pitiful face with their identical features, then bite Gin's neck as he cried.

"Big brother's bullying me."

He was timid and cowardly.

More than once, Gin wanted to kill the pretty boy on the spot. Then one day, he saw him nimbly draw a Beretta and press it against Rum's forehead.

His voice was still soft and sweet. "Rum, you asked who I am? I'm GIN, of course, the top killer from another world."

"Gin is such a loser. He's so old and still hasn't managed to become the organization's boss. It's time to let him experience the shock a master con artist can deliver."

Gin sneered.

Hah, he's no pretty boy. He's just a little liar.
