Kori Shishido (宍戸氷, Shishido Kōri) is an anti-hero in Naruto Keishō and one of the title characters in Shishido Gaiden. He is a survivor of the Shishido clan and the twin brother of Jūbei Shishido. He has the rare Kekkei Genkai of the Yuki Clan, the Ice Release. Though born a few minutes after his brother, unlike his twin he inherited the Ice Release which Jubei did not. For this reason he is known as the Ice Demon of Iwagakure (岩隠れの里の氷の悪魔, Iwagakure no Kōri no Akuma). He is also the jinchūriki of the Five-Tailed Dolphin Horse (五尾のイルカ馬, Gobi no Irukauma) and acts as the guardian of Iwagakure. His battle prowess has also earned him the title of Kirā (キラー, Killer).
Kori is a short, fair skinned young man with a highly youthful appearance. He has turquoise eyes and short, spiked, white hair.
