Kurikara Sword

Lore & Background

The existence of Kurikara is tied directly to the revelation of Rin and Yukio Okumura's parentage. When Satan kills their guardian, Father Shiro Fujimoto, in an attempt to protect them, Rin draws the sword known as Kurikara (倶利伽羅). This act triggers a transformation where Rin not only manifests demonic features like fangs and a tail but also unlocks the power of blue flames that can destroy nearly any object or barrier. The sword functions as the physical restraint for these powers; without it, Rin's nature is fully unbound. The weapon is central to his enrollment at True Cross Academy, an exorcist cram school under the True Cross Order, where he studies under his twin brother Yukio to master this power and ultimately defeat Satan.

In Their Own Story

The pivotal moment for Kurikara occurs when Rin learns that he and his younger twin brother Yukio are the sons of Satan. Following the death of Father Shiro Fujimoto, who died protecting Rin from Satan, Rin draws the demon-slaying sword Kurikara. This action immediately grants him demonic features, including fangs and a tail, and unleashes blue flames that destroy almost anything he touches. Driven by the desire to become stronger than his guardian and defeat Satan, Rin uses this power as motivation to enroll at True Cross Academy. There, under Yukio's tutelage, he begins his journey to master the sword and his heritage, accompanied by fellow students who quickly become close friends.

Reader's Guide

To effectively use Kurikara, one must understand its dual nature as both a weapon and a seal. When drawn by Rin Okumura, it triggers his transformation into his demonic form, granting access to blue flames that possess immense destructive capability. However, the sword also acts as a restraint; it is the mechanism that allows Rin to manage these powers rather than being consumed by them. For an Exorcist training at True Cross Academy, mastering Kurikara involves learning to control the blue flames while maintaining human consciousness. The sword's power is specific to those with a connection to Satan's lineage or immense spiritual fortitude, as it channels the energy of Gehenna into Assiah for the purpose of protecting humanity.
