The '''Oathkeeper''' is a [[Keychain]] for [[Kingdom Key|Sora's Keyblade]] introduced in  ''{{c|Kingdom Hearts|game}}''. It also appears as half of [[Roxas]]'s [[Oathkeeper & Oblivion|dual set]] of Keyblades alongside the [[Oblivion]], and was transformed from his original Kingdom Key after [[Xion]] returned to Sora. Fundamentally, the Oathkeeper is symbolic of Sora's memories of [[Kairi]].<ref>'''''{{w|Weekly Famitsu}}'''''<!--If anyone knows which volume issue and page this is, please add it-->, '''Tetsuya 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!?" [https://www.khinsider.com/news/Famitsu-showcases-Kingdom-Hearts-HD-2-8-Nomura-interview-released-8108 Translation via KHInsider].</ref>

==Development==
Originally, the Oathkeeper was meant to have a [[paopu fruit]] as the Keychain's token.<ref>'''''[[Kingdom Hearts Ultimania#Kingdom Hearts Ultimania|Kingdom Hearts Ultimania]]''''', '''Tetsuya Nomura:''' "In the early stages we called it the "Kairi Keyblade," and I was envisioning giving it a paopu fruit keychain." [https://www.khinsider.com/news/A-Look-Back-KINGDOM-HEARTS-Ultimania-Gallery-Comments-Part-1-15519 Translation via goldpanner].</ref>

==Story==
===''Kingdom Hearts''===
The Oathkeeper is formed when Sora uses Kairi's [[Wayfinder]] as a Keychain. After rescuing her from [[Hollow Bastion]], Kairi gives him the charm for luck in the [[Secret Waterway]] in [[Traverse Town]].

===''Kingdom Hearts Chain of Memories''===
When Sora enters [[Castle Oblivion]], [[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. He then obtains the first Oathkeeper card afterwards.

===''Kingdom Hearts II''===
Although Sora continued to possess the Lucky Charm after awakening from his hibernation, he is not able to use the Oathkeeper until he returns to [[Twilight Town]] and learns where Kairi had been taken.

==Design==
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. 

In ''Kingdom Hearts III'', the two white points in the teeth of the blade are now darkened. The heart shape next to it is now bigger and level with the teeth. The angel wings making the guard are now yellow and blue, matching the teeth. The heart shape at the bottom of the blade is now hollow.

When the Oathkeeper is summoned in ''Kingdom Hearts II'', it emerges in a bright, yellowish-white light. When summoned in ''Kingdom Hearts III'', it appears in sparklingly light and feathers.

The Oathkeeper's English name stems from its Keychain, Kairi's Wayfinder, being a reminder of Sora's promise to her. Its Japanese name, "Promise's Charm," also reflects this status.

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

===''Play Arts Figures''===
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]]''.

==Gameplay==
In ''Kingdom Hearts'', the Oathkeeper has a decent reach and is well-balanced, making it an acceptable substitute for the [[Lionheart]].

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'', this Keyblade's ground combo begins with a thrust forward, followed by a diagonal vertical strike from the right side, and continues with a lightning-fast rush consisting of a horizontal slash left, the same slash right, and a vertical downward slash and ending with a jump back and a rushing diagonal spinning slash. Pressing {{button|dsy}} after the first upward slash will trigger a jump into the air and a slightly angled spinning slash. The aerial combo is a rush forward and two downward spinning slashes from either side.

In ''Kingdom Hearts Re:coded'', the Oathkeeper's Clock abilities are the best defensive abilities among all the Keychains in the game.

In ''Kingdom Hearts III'', the Oathkeeper has balanced magic and strength stats, and along with its [[MP Converter]] ability the Oathkeeper is slightly more geared towards magic than its counterpart the Oblivion.
