The Crossover Choice Mission System

A shut-in from Earth died after being electrocuted, then transmigrated to the world of One Piece and became Luffy's older brother. At the age of ten, he awakened the System.

Kaido: I really can't even die when I want to! Lu Fan: How about I kill you, then?

Shanks: No one can withstand my Haki! Lu Fan: Are you kidding me?

Lu Fan: Enough talk. All of you, come at me! You're all just little brothers!

The three worlds planned so far are One Piece, Akame ga Kill!, and Super God Academy.
