After the Teenage Mutant Ninja Turtles Were Reborn, They Vowed to Add a Little More Green

An Hezai, a ninja turtle of his generation, is reborn. In his previous life, his wife and boss openly cuckolded him, his boss humiliated his daughter, and his parents killed themselves. He had planned to shed his shell and start over, only to discover that he had become one of the lucky few with a cheat. So should he keep carrying that shell or not?

Unable to bear the thought of it, he exploits a freshly assembled System's bugs and earns a permanent punishment achievement.

Other people's cheats let them dominate the world or win women's hearts. An Hezai, on the other hand, dutifully sorts garbage, determined to make the Earth a little greener.
