Uraurashima  

, 裏浦島

The manga "Uraurashima" (also known as "Reverse Urashima") is part of the series "Fractured Fairy Tales." In the Semi-Finals, it fights against Kurama. To deceive Kurama into thinking he was fighting unwillingly, Uraurashima used the Idunn Box (which in this context functions as a reverse treasure box). However, the magic proved too effective and turned Kurama back into his original form - that of Yoko, a ruthless thief. In an attempt to extract information about the Idunn Box from him, Yoko tried to torture Kurama. He was eventually killed by Shishiwakamaru when he impaled himself on the demon's sword after throwing it at the barrier. It is later revealed that Uraurashima was actually a disguised lesser demon. His character draws inspiration from the story of Urashima Tarou.
