Another side, Another story...
Another side, Another story is the secret ending of Kingdom Hearts, and the first one of the series. It was later expanded in Kingdom Hearts Final Mix's secret ending, Another Side, Another Story [deep dive].
A hooded Roxas walks through the Dark City in the pouring rain. He stops, feet away from the base of Memory's Skyscraper. Roxas looks up at the screens; shortly after, his head shifts down as many Neoshadows rise up from the ground and surround him. A blindfolded Riku, wearing a Black Coat, stands on top of Memory's Skyscraper and stares down at Roxas. Roxas draws the Oathkeeper in his left hand and Oblivion in his right. He spins the Keyblades above his head, yielding sparks, and holds them out to his sides. Riku tilts his head up to the sky and holds his arms out; the clouds above the Skyscraper part to reveal a meteor shower. A white-purple outline of the Heartless emblem surrounds Roxas. Riku takes off his blindfold and throws his head back.
"Birth by sleep"
Birth by sleep is the secret ending video to Kingdom Hearts II Final Mix and a follow-up to "The Gathering", the secret ending video to the original Kingdom Hearts II. The video centers around three armored warriors wielding Keyblades and an unnamed foe. It is a teaser for Kingdom Hearts Birth by Sleep.
Synopsis
Picking up where "The Gathering" left off, the three Keyblade knights, Terra, Aqua and Ven are approached by an old man, Master Xehanort, and his apprentice, Vanitas.
The two are charged by Terra, and Xehanort responds by shifting the earth beneath them to create a rising plateau that carries Terra above the rest. Xehanort then lifts the ground beneath himself as well, creating a cliff much higher than the surrounding terrain. While Vanitas strikes Terra with Thunder, and is immediately pursued by Aqua and Ventus, Terra chases after Xehanort, who creates a Keyblade infused cyclone to aid Vanitas against Aqua and Ventus.
Vanitas chases and battles Aqua and Ventus on the cyclone, and neither are able to overcome him. Noticing that Terra is getting closer to Xehanort, Vanitas directs the cyclone towards Terra, knocking him off the cliff. Aqua and Ventus watch in horror, and Aqua gets hit by the cyclone, crashing to the ground, obliterating her helmet completely. Ventus comes to her aid as she casts Reflect magic on Terra to protect him from the cyclone. The spell protects him from the cyclone until the he is pushed up to where Xehanort is, at which point it explodes, blasting the cyclone to pieces. Terra is dropped to where Xehanort is. Terra briefly duels Xehanort until the old man freezes his left arm. Ventus attempts to attack Xehanort from behind, but Xehanort teleports himself behind Ven and grabs him by the helmet, beginning to crush it. Terra stumbles forward, probably in an attempt to help Ven, until Vanitas and the Keyblade infused cyclone inexplicably reappear below Terra's feet, hurling him off the cliff as countless keyblades batter his body. Xehanort and Vanitas stand at the top of the cliff, still holding Ven, presumably so Aqua could see him. When she does, Xehanort first burns and then freezes Ventus. As Aqua looks on in horror, Xehanort throws him off the cliff, and his keyblade shatters on a rock. Aqua catches his body and he is revealed to have a striking resemblance to Roxas. Though frozen, he moves his eyes to indicate that he is still alive.
Xehanort's Keyblade is changed into a purple and blue ball of flame-like energy, which he shoots upwards to part the gathering dark clouds, revealing what appears to be Kingdom Hearts by means unexplained. Terra, barely able to stand, tears off what remains of his helmet to look up at Kingdom Hearts and begins to succumb to the darkness, shown by his eyes turning yellow.
The video ends with Mickey Mouse looking at the battlefield from a distance, holding the Star Seeker Keyblade and on the verge of stepping in to fight Xehanort and Vanitas.
