A Detective's Life from Scratch

Bourbon died, got bound to a strange System, and transmigrated into a parallel world where he was a detestable cop. If he wanted to return to his original world, he had to follow the System's instructions and complete its role-playing missions. To come back to life, he diligently began playing his assigned roles. An organization member tamed by an undercover agent, a bomb disposal officer who died and came back to life on the other side, an undercover agent who idolized the top-tier killer... Every role's actions went against their position, yet came with high-minded justifications. They were nothing like him, a man who had stained himself with darkness for his family. Bourbon: ... He was sure someone wanted him dead. * After playing all those ridiculous roles, Rei Furuya not only survived, but came back to life. In the darkness, someone reached out to him and led him, step by step, back into the sunlight. Tips: 1. It's more or less what it sounds like: Rei's science-filled life. 2. The CP should be settled, but I'll keep quiet for now x 3. I've reworked the premise, so some details will differ from before. 4. There will definitely be OOC. Theme: I'll take you back into the sunlight
