Honestly i dont know the ship name for luna and neville. anyways i think this ship is adorable!! i do ship it , yes they didnt end up together :( but remember in one of the movies neville said he liked luna? idk i thought it was cute. My reasoning for shipping them is because they are both sweet caring characters, idk i think they would be a happy compatible couple (next up is drarry , harry and draco , yikes)
