ONE PIECE Heroines is a collection of short stories written by Jun Esaka and illustrated by Sayaka Suwa. It highlights the heretofore unseen lives of the women of the manga and anime. The first volume of the series focuses on Nami, Robin, Vivi, and Perona. The second volume shifts to Hancock, Tashigi, Reiju, and Uta, with the final chapter being a conversation between Nami and Robin about the Straw Hats crew. Viz Media publishes both books in English, and describes the first volume as such:
Go behind the runway as style icon Nami stars in a life-changing fashion show, observe wise Robin as she helps to decipher an ancient tablet with Koala and Sabo, watch as solemn Princess Vivi receives a love letter from an unexpected admirer, and check out Ghost Princess Perona’s battle over the last bottle of wine with Zolo and Mihawk!
