MfEI MAMI feels Eternal Innocence - a kind of TRIBAL LINK - is a CD by Mami Kawada which features the first opening theme song of the Shakugan no Shana anime series, Hishoku no Sora, as well as two opening theme songs from the anime, Toaru Majutsu no Index, which were also sung by Mami Kawada. The CD was a reward which came along with the purchase of Mami Kawada's single Borderland, which was featured in the anime, Jormungand, or her album SQUARE THE CIRCLE, which contains the last opening theme song of Shakugan no Shana, Serment. The cover of MfEI depicts Shana with Index Librorum Prohibitorum from Toaru Majutsu no Index.
