Dragon's Soul, a Kingdom Hearts Fanfic

Prologue

Mickey was wondering Twilight Town, when he saw Unversed pop up and start attacking a boy. Mickey was about to jump in and help, but they turned into purple smoke in an instant. In front of him stood the same boy, but now he was clutching a keyblade in his hand, a keyblade Mickey recognized as Dragon Flame, the dragon wing near the end being a dead giveaway. Mickey knew that he had to take the boy to master Yen Sid immediately.

"You there, what's your name?" Mickey asked the figure in front of him. 

The boy, startled by Mickey's presence, responded with, "My name is [Y/n]. If you want to know about this," he held up the keyblade, "I have no idea what it even is. It just popped into my hand. I've never seen it before now." 

Mickey knew [Y/n] was scared, so he told him, in a calm voice, "I'll teach you all about it, but I need you to come with me to Master Yen Sid."

"Prove you know something about it! Show me that you have one too!" [Y/n] yelled, wanting proof before trusting the mouse. 

Mickey summoned his keyblade to his hand, "My name is Mickey Mouse." Mickey beckoned [Y/n] to come with him. He knew it was the only way he could learn how to use this power to help others. It's what he's spent his entire life doing, and never wanted to stop.

He walked over to where Mickey was standing. The mouse led him to a train station where they boarded a train with a wizard hat. "Never seen that train before. How's this gonna help us, though? I've been on every line that this station will take you to, and I've never seen anything regarding that blade I had earlier." [Y/n] stated, confused as to what the mouse was thinking. 

"Don't worry about that right now, just get on the train." Mickey told him, his expression frustrated, yet he still smiled. [Y/n] found it creepy that no matter what emotion he was feeling, he smiled.

After boarding the train, it took off. After about ten minutes, it seemingly went off the tracks, but then glowing green tracks appeared underneath the train. 

"What's going on?" [Y/n] asked worriedly. 

"Don't worry, it'll all be fine."  Mickey told him, with the same smile on his face. [Y/n] decided not to worry and stay put. Suddenly, the train stopped, and Mickey stood up, [Y/n] following his movements.

When [Y/n] gets out, there is a massive tower decorated with stars on it's blue roof. "This is the home of Yen Sid, a former Keyblade Master." Mickey explained. 

They went through the small door, and [Y/n] looked up to see a tall, spiraling staircase. "Oh boy." He said, not looking forward to having to climb all those stairs. 

"The sooner we start climbing, the sooner we'll reach the top." Mickey told him,

[Y/n] now stood in front of a man with a long, gray beard.

Yen Sid: You say he summoned a Keyblade?

Mickey: Yes. It was apparently his first time.

Yen Sid: Boy, is this true?

[Y/n]: Yes, sir.

Yen Sid: I am not the teacher I used to be, and therefore, I believe there is only one person I can send you to so that you can learn.

Mickey: Right. Master Eraqus.

___________________________________________________________

It's been about five years. [Y/n], now seventeen, has been training under a man named Master Eraqus in the Land of Departure with three other Keyblade wielders. Terra, who felt like his older brother, Ventus, who felt like his younger brother, and Aqua, his best friend and most frequent sparring partner. He had also developed a small crush on the blunette. He just found everything about her to be amazing, whether it was the way she wielded her Keyblade or how she talked to him when he was stressed about something.
