"Ultima Latio! Vulnerant Omnes, Ultima Necat... Bibliotheca Pan Magica!"

Shiori unleashing her true power

Bibliotheca Pan Magica (万魔図書館 (ビブリオティカ・パンマギカ) Biburiotika Panmagika; lit. "Magic Library" in Latin, "Myriad Grimoire Mansion" in Japanese) is Shiori Momono's most powerful attack, used in the final phase of Sin, Damnation and the Atonement Girl arc to defeat a dragon. While being one of the powerful attack in 11eyes, performing the attack requires full access to her inner grimoire library. This means that she has to open the restriction on her body first, then open the library on the battlefield to prepare a kill zone. When used, a gigantic golden magic circle appears behind her and the floating grimoires. After a full incantation and charging time, the attack is released from her chest, completely obliterate everything on its path.
