The {{nihongo|'''Oathkeeper'''|約束のお守り|Yakusoku no Omamori|lit. "Oath's Charm"}} is a [[Keychain]] for [[Kingdom Key|Sora's Keyblade]] which appears in  ''[[Kingdom Hearts (game)|Kingdom Hearts]]'', ''[[Kingdom Hearts: Chain of Memories]]'', ''[[Kingdom Hearts II]]'', ''[[Kingdom Hearts 358/2 Days]]'', and ''[[Kingdom Hearts Re:coded]]''. It also appears as half of [[Roxas]]'s dual set of Keyblades alongside the [[Oblivion]], and was transformed from his original Kingdom Key after he absorbed [[Xion]]. Fundamentally, the Oathkeeper is symbolic of Sora's memories of [[Kairi]].<ref name="Famitsu">'''''Famitsu'' Interview'''; '''Nomura''': "The Keyblades the boy who knows Sora is holding are the Oathkeeper and Oblivion from the first game. The precious "Oathkeeper", which [[Sora]] received from Kairi. The jet-black Keyblade, symbolic of [[Riku]]. / The Oblivion, at first, was called Riku's Keyblade. The boy who has the Keyblades from Riku (darkness) and Kairi (light)......Who is he!?"</ref>

The Oathkeeper is formed when Sora uses Kairi's [[Wayfinder]] as a Keychain. After rescuing her from [[Hollow Bastion]] in ''Kingdom Hearts'', Kairi gives him the charm for luck in the [[Traverse Town#Secret Waterway|Secret Waterway]] in [[Traverse Town]]. When Sora enters [[Castle Oblivion]] in ''Kingdom Hearts: Chain of Memories'', [[Naminé]] rewrites Sora's memories, replacing Kairi's Lucky Charm with what appears to be a trinket from herself.  After Sora defeats the [[Darkside]] at [[Destiny Islands]] and speaks with Naminé, she reveals the truth, and the illusion is dispelled.  Although Sora continued to possess the Lucky Charm throughout ''Kingdom Hearts II'', he is not able to use the Oathkeeper until he returns to [[Twilight Town]] and learns where Kairi had been taken. In ''Kingdom Hearts Re:coded'', Data-Sora obtains the Oathkeeper Keychain after he fought a [[Game:Data-Roxas|hooded boy]] and learns the truth behind the mysterious message that appears on Jiminy's first journal.  

The Oathkeeper's shaft displays two hearts, and its handle bears two angel wings, contrasting the bat wings that comprise Oblivion's handle. The teeth are fashioned in the shape of the Kanji for "light" (光), corresponding to the Oblivion's kanji for "darkness". Its Keychain token is Kairi's Wayfinder, a star sewn together from [[Thalassa Shell]]s. In Castle Oblivion, it is replaced by Naminé's trinket until the illusion over Sora's Thalassa Charm breaks. When it is summoned by the user, Oathkeeper emerges in a bright, yellowish-white light.

A limited edition Oathkeeper was released with four other Keyblades in a special ''[[Play Arts Figures]]'' accessory set, ''[[Play Arts Figures#Play Arts Arms|Play Arts Arms]]''.

In the intro of ''[[Kingdom Hearts 3D: Dream Drop Distance]]'', Roxas is shown dual wielding the Oathkeeper and Oblivion against Axel; Sora also wields the Oathkeeper against Xemnas, while Riku uses the Oblivion.

The Oathkeeper has a decent reach and is well-balanced in ''Kingdom Hearts''; Oathkeeper is a good substitute for the [[Lionheart]], in case the player hasn't been able, or didn't want, to defeat [[Cloud]] and [[Leon]] in the [[Hades Cup]]. In ''Kingdom Hearts II'', its ability of Form Boost makes it much more useful for leveling Sora's [[Drive Form]]s, rather than for regular battle. In ''Kingdom Hearts 358/2 Days'', the Oathkeeper's combos are exactly the same as the [[Two Become One]] Keyblade. In ''Kingdom Hearts Re:coded'', Oathkeeper's Clock abilities are the best defensive abilities among all the Keychains in the game.
