Lucina took Corrin to the third hallway coming out of the portal room.
"First thing I see is that you're a sword fighter too." Lucina commented.
"Yeah, well..." Corrin gave Lucina a grin.
"So how does this whole dragon thing work?" She wondered.
Corrin concentrated hard, and felt the familiar transformation. He grew above Lucina and decided to let out a roar just for show.
A certain blonde princess in a pink dress chose that exact moment to walk around the corner. Peach shrieked and ran back to wherever she came from.
Corrin transformed into a human and laughed with Lucina. He looked into her eyes.
"You have very nice eyes." He said suddenly, wondering where it came from.
"Oh, um..." Lucina looked away shyly. "Thanks." She muttered. She felt safe in the Smash Castle but she would never feel right telling someone about that mark.
"So here is a new room we added for training recently." She changed the subject suddenly. "We call if the multi-man smash room."
They walked up to a clear glass wall, and saw a replica of Battlefield inside an enormous room. Falco was currently smashing through a bunch of Miis that were constantly assailing him.
"None of us really knows how this room works or how in the world we happen to have an endless supply of Miis." Lucina explained. "But you can choose to just smash forever for practice if you want. Lombardi definitely takes his time here though."
Then the speakers lit up with that announcer's voice: "Cloud, Corrin, and Kamui, report to the stage room. Stage: Wily Castle."
"I'm sorry." Lucina looked at Corrin apologetically.
"What? It'll be fine." He said confidently.
"We all hate that stage." She laughed nervously. "You'll see why."
Corrin entered the stage room and found Kamui and Cloud already waiting for him. They entered a door with a gear symbol over it.
They exited into a rather flat stage, with only some platforms idly floating around. There was a unique techy-looking castle behind them. Corrin wondered what Lucina could have meant about this stage being horrible.
"3...2...1...GO!" The announcer called. Kamui and Corrin eyed each other, knowing how the other fought. While they examined each other, Cloud jumped behind them and slashed downward, putting Corrin on the ground. Kamui dashed forward and drove her sword into Cloud. He got up just in time to be hit by Kamui's sword whirling upward. Cloud was constantly on the ground, getting defeated, witnessing the smooth transitions between dragon and human. Just when he thought he would be knocked out, a bunch of yellow blobs began to fall from the sky. They landed to form some sort of big yellow creature. He didn't care what it was because it separated him from them while he got up.
Kamui observed the creature that appeared to have a single eye or some other apparatus on it. She was curious, and then it shot her. Huge blasts of energy more painful than she had felt before struck her chest and she was violently knocked to the ground. She managed to get up just in time to see its yellow mass come flying at her. She was tossed around and couldn't land for what felt like an eternity. Kamui had witnessed the reason that all smashers hated this place. She was being defeated by someone, or something, that wasn't even in the battle.
Then the strangest thing happened. The air behind them opened up, like it was ripped open. There was a large purple gash in space itself, and a huge gust of wind began to pull into it. The yellow monster thing got swiftly pulled into it, and then the gash disappeared as if nothing had ever happened.
Kamui looked back to see that Cloud was nowhere to be seen. She had only to defeat her brother now. They sparred off for a very lengthy time, getting in small hits whenever they could. Corrin was defeating her for the most part, but Kamui's sword delivered the final blow that sent Corrin off of the stage.
The three fighters had returned to the stage room, ready to go freshen up from a hard battle, maybe take a nap. Corrin thought maybe he would go see Lucina.
But the scene was not peaceful, as it was before they left to battle. There were bright flames and charred holes all over the walls and floor. Around the corner, there was the sound of a massive explosion accompanied by a great amount of yelling.
The three fighters looked at each other, and as one they ran to see the trouble.
Then they saw the monstrosity they had just faced. That yellow demon was tromping through the halls, shooting everyone and everything it saw. Falco, Link, Ike, Rosalina and her Luma were already trying their hardest to slow its progress. As Cloud, Corrin and Kamui ran to aide them, Diddy Kong, Samus, Luigi, and Lucina appeared to help. Wario came around the corner, obnoxiously revving one of his bikes.
They fought with all they had, but they only slowed it down. It hit Link and he fell to the wall, unconscious. It Wario's motorcycle and created a huge explosion that put Lucina out of the action. Diddy Kong had disappeared, and Luigi had been knocked to the ground, unable to rise. Just when they were losing all hope, a huge white hand came flying around the corner. Master Hand grabbed the abomination and carried it off quickly.
Corrin looked around at the destruction it left. Only then did he notice his sister, on the ground, clutching her sword tightly. He ran to her and knelt by her side silently.
"Kamui!" He looked up and Ike ran over to her. She looked into Ike's eyes. A silent communication happened. "I'll be fine." She tried to smile.
Master Hand came flying back, empty handed. "The protection the stages offer is not functional here. These are serious injuries. They need treatment." He gathered up all the wounded and rushed them to the hospital wing.
Master Hand called an assembly of the entire roster in the hospital wing to include the injured. Full assemblies almost never happened outside of roster changes. Corrin and Ike both fought to sit with Kamui, but Corrin decided to support Lucina.
Master Hand spoke, "Does anyone know how this happened?" Corrin could have sworn Master Hand was glaring at them. For the first time in the history of the Smash Castle, all was silent. All of them, even Bowser and Ganondorf, were looking down dejectedly.
"Nobody?" He waited in silence for a long time. "Cloud, Kamui, Corrin, you all witnessed nothing?"
They stayed silent.
"This is the first major security breach that the Smash Castle has ever seen. And it happens right after you three join us." Master Hand was clearly frustrated at this point. "I don't know how, but anything could happen. Everyone be ready for anything at all times. You are dismissed."
"Cloud, Corrin, stay here with Kamui awhile." After everyone had left, Master Hand spoke. "I have no proof, but I must keep close tabs on you three. It can't be a coincidence that this happened immediately after you joined us." He thought for a bit an continued. "I know it's a harsh thing to say, but...I'm blocking you three from all battles until we figure this out. I'm sorry it had to begin this way, but the portals will now be closed to you."
