He wakes up one day bound to the Deathday Rewind System.

His deduction skills rival Sherlock Holmes, his showboating puts Kaito Kid to shame, and his crimes outclass Gin from the Black Organization... Sorry, none of that is true.
Protagonist: "I could have all that! First, though, I need to save my sister. My sister, who was raised to be a child bride, dies from the start, so what's the point of showing off?"
His sister dies, and the protagonist kills himself!
The end.
System: "Want to die? Rewind!"
