This cube craft paper toy is the Chrome Dokuro, based on the anime and manga series Reborn. This paper craft model is designed by blackignus. Nagi, known as Chrome Dokuro, is a 13-year-old Japanese girl who was first introduced as Tsuna's mysterious Mist Guardian and one of Mukuro's subordinates who acted as his vessel and connection to the world outside Vendicare Prison.
Chrome is a girl with short purple pineapple hair like Mukuro with a single violet eye. She's mostly seen wearing a green Kokuyo Middle-school uniform like the rest of Kokuyo Gang, a black eye patch, a black belt, and boots that all have a chrome-colored skull on them, reflecting her own name, Chrome Dokuro. She always carries her bag, which is where she puts her trident in. When in an illusionary world, she has longer hair with her bangs covering her lost right eye, and always shown wearing a plain white gown. In one of manga chapters covers, she's shown wearing a sailor uniform. However, her appearance before she was in her fatal car accident as Nagi was not seen.
Due to her once anti-social life as Nagi, she never opens up to anyone except Mukuro, the first person who accept her as she is, and always gets confused and shy when someone is kind to her since she had never imagined that her existence could be accepted by people. Because of her nature, some people can't be honest with her or think of her as pitiful. She used to tend on Mukuro for help, but as the story progress, she becomes determined to get stronger to help the people who are dear to her and slowly starts to interact with the others.
