Detective Conan: Help, My Brother Is the Distillery's Hardest Worker

[Toru pairing. The protagonist is a Public Security officer, and has an illness he doesn’t know about.]

After waking up, Kurozawa Tomoya found himself lying in a bathtub full of water, with blood still flowing from his wrists. Had he tried to kill himself? He clearly remembered watching anime, and then dozing off for a moment. How had he ended up in another world?

The electronic voice in his head was real, and so was everything around him. Most importantly, he’d become Gin’s younger brother. And in this world, he was a Public Security officer while his older brother was a killer. An officer brother and a killer brother? He was doomed!

As a police officer in both his lives, he couldn’t give up his career, nor could he lose the only family he had.

Kurozawa Tomoya knew all too well what a shambles the organization was. It was crawling with undercover agents, the driver and his underlings were clearly a bit dim, and in the whole enormous organization, his brother was the only one actually doing any work. Rum even kept trying to trip him up!

Bro, this is a waterworks, not a distillery! Why not switch sides? Rather than keep doing thankless work, you might as well take a different, more promising path.

From then on, Kurozawa Tomoya was either rescuing his brother or on his way to rescue his brother.
