Shiro Fujimoto received Kurikara from Tatsuma Suguro after he abruptly intruded when Tatsuma's wife was giving birth.
Shiro used the blade, with the aid of Mephisto, to seal Rin Okumura's Demon heart into the Kurikara at birth, thus fusing it with his blue flames inherited from Satan. This let Rin stay a human for 15 years until the sword could no longer contain that power. It is now under possession of Rin, which he can unsheathe Kurikara to restore his Demonic nature and powers. Kurikara is often in a red sheath on Rin's back. Rin holds true to Shiro's command to keep Kurikara with him at all times and even sleeps with it at night.
In the anime, during Rin's battle with Amaimon during the ExWire's training in the forest, Kurikara was damaged and cracked. This allowed Rin's powers to overflow and the sword was no longer able to restrain his demon heart and nature from taking over. Using nails that contain special metal from the temple destroyed on Blue Night, a female blacksmith is able to restore the sword, but warns Rin that it is not perfectly restored and that it could break again with no way to fix it.
