This should have been obvious, and unfortunately it is as much a tried trope as any.
Imu’s ability, Domi Reversi, turns its victims into a demon/an evil version of themself. But, in order to do so, they must be impure. He has been able to corrupt those who are not perfectly good.
Luffy will be the sole person immune to Domi Reversi, as there is no evil within him.
Remember how important Skypeia is? The only reason Enel lost was because Luffy was the sole person immune to his ability.
Luffy is invulnerable to the powers of Gods.
