Takada's death would ultimately result in Light's downfall. Unbeknownst to Light as he wrote Takada's name in his torn off piece of the Death Note, Mikami had visited his safe deposit box and wrote down Takada's name in the real Death Note just one minute later, unaware Light had the same intention. This allowed Near's right-hand man Stephen Gevanni, who'd been following Mikami, to discover the real notebook and Mikami's deception. This ultimately allowed Near to expose Light and Mikami as Kira and X-Kira, leading to their deaths and ending Light's reign as Kira (which is hinted to have been Mello's true reason for kidnapping Takada and knew it would likely cost him his life).
