Eternal Session is a limit that appears in Kingdom Hearts II. Together, Sora and Riku can use the joint attack, Session.

Mechanics

In Kingdom Hearts II, Eternal Session is an action ability exclusive to Riku. It costs 3 AP to equip and all of Sora's MP to use. The limit begins with Session (セッション, Sesshon), in which Sora and Riku perform a rapid flurry of attacks. Then, Last Saber (ラストセイバー, Rasuto Seibā) becomes available in the Attack slot, in which Sora and Riku rapidly stab an enemy with their Keyblades, and Dark Cannon (ダークカノン, Dāku Kanon) can be used as a Reaction Command, allowing the duo to fire a barrage of dark orbs at enemies. Afterwards, Sora and Riku turn their backs toward each other, and the next phase of the Limit begins. Overriding the Attack command, XIII Blades (XIIIソード, XIII Sōdo, lit. "XIII Swords") has the duo linking arms and summoning thirteen swords to perform a spinning slash attack. After using Last Saber or Dark Cannon twice, the next technique, Master Hearts (マスターハーツ, Masutā Hātsu), is used automatically and involves Sora and Riku coating their Keyblades in an aura. Riku is handed Sora's Keyblade and slashes at enemies with it alongside his own, before passing both Sora's Keyblade and Way to the Dawn to Sora so he can do the same. After XIII Blades or Master Hearts is used twice, All's End (オールオーバー, Ōru Ōbā, lit. "All Over"), can be used, in which Sora and Riku's Keyblades float side-by-side in energy orbs that reel in enemies before exploding. The two then bump their fists together after the final attack has finished. During the limit, Sora can move around freely. The limit can be cancelled early through the Stop (やめる, Yameru) command in the Limit slot.
