Rudeus Tried Speaking Japanese and English to Lucy Funfact Because Lucy was an unusually quiet baby who rarely cried, Rudeus began to wonder if she might be a reincarnated person from another world, just like him. To ease his concerns, he deliberately spoke to Lucy in Japanese and English to see if she would react. Rudeus: "You know by now, don't you? This is a parallel universe." Unfortunately, Lucy only smiled and babbled like an ordinary baby. In the end, Rudeus realized it didn't matter whether Lucy was a reincarnated person from another world or not. She was his daughter, and he would protect and raise her with love, just as Paul had always protected his own family
