Red and Black Reversed, but I'm the Undercover Agent

In one sentence: In a world where the colors of the Black and Red sides are reversed, the protagonist, a police undercover agent, uses the original manga to give everyone a childhood filter.

Faced with Black Su, Black Toru, Black Shuichi, and Black Conan, he pours out his heart with tears in his eyes.

Faced with Red Gin, he shouts "No way!" and refuses to give in to the death.

All in all, it's a story about a silly little rabbit falling into a trap without realizing it, while the fatherly Red Gin on the sidelines gets so angry he wants to smack him.

Theme: A bright future
