Isagitsune

Isagitsune (イサギツネ Isagitsune?, 17): Isagitsune is an Ayakashi master of the black arts with knowledge of 100 spells, armed with the Teni Yōsenken (天為葉扇剣?, Natural Leaf-Fan Sword). Using his Fox Concealment Spell (狐隠れの術 Kitsune Gakure no Jutsu?), he steals a hair from Takeru to conduct his Mirror Reflection Spell (鏡映しの術 Kagami Utsushi no Jutsu?) to spy on Takeru to look for the sealing character until his cover is blown. His other spells include Fox Whirling Spell (狐つむじの術 Kitsune Tsumuji no Jutsu?), Foxfire Spell (狐火の術 Kitsunebi no Jutsu?), Fox Throwing Stones (狐つぶて Kitsune Tsubute?), Fox Technique Reversal (狐技返し Kitsune Waza Gaeshi?), Copycat Fox (真似狐 Mane Gitsune?), and Yatagarasu Spell (八咫烏の術 Yatagarasu no Jutsu?). He is killed by Shinken Gold, and then destroyed by Tenku Shinken-Oh with help from Ika Origami. His name comes from the term "Kitsune" while being the basis of the Tengu (天狗?) of Japanese myth.
