DaiDai and Olif are a detective duo (insisted by Olif) to uncover the mysterious case of Nero.
EmyEmy became friends with Olif after she protected him from bullies at school, unknowningly saving the bullies from Olif's magical retaliation. She became aware of his magical powers later, but still acts very protective of him, like an older sister.
RevisRevis is Olif's older sister. She is chasing Olif around the world to bring him back to home.
