Fish-Man Island Arc

Luca's name was announced by Hody Jones as one of the people who supported Otohime's idea of relocating the population of Fish-Man Island to above the sea surface and living with humans. As such, she was considered a "traitor" to Fish-Man Island by the New Fish-Man Pirates and fated to be "dealt with", much to her terror.[1]
