I've been deciding between two different fics to write, so this took me a little while to get out. I was choosing between an AU and a Crystal Tokyo origin story, and I decided on the AU. It isn't going to be very long, so it will give me time to prepare for the Crystal Tokyo fic which will be probably the longest piece I've written.

Updates for this may not be very consistent, considering my schedule is packed.

This is based on the 90s anime, but Mamoru is the same age as he is in the manga, making him 23.

Enjoy!

Mamoru looked out the window, watching as the ground began to grow closer and closer. "Ladies and gentlemen, as we start our descent into Tokyo, Japan, please make sure your seats and tray tables are in their full upright position. Make sure your seat belt is securely fastened and all carry-on luggage is stowed underneath the seat in front of you or in the overhead bins. Thank you," the loud voice of the pilot boomed over the speakers. Mamoru tore his eyes away and rested his elbows on the armrests. He subconsciously ran a hand through his unruly black hair. Even at such an ungodly hour, he was wide awake.

It had been four years since he had been in Japan. Four years since that godsend of an acceptance letter came in the mail and took him away from all of his problems. Studying at Harvard had always been a dream of his, and he had finally fulfilled it. He spent four years studying excessively, preparing to become a doctor like he always hoped he would be. Those years had flown by, and now here he was, on a flight back to Japan to begin an internship at Juuban Hospital.

He was planning on staying in America permanently and getting an internship at a hospital in Boston, but the offer at Juuban was just too good to pass up. He would be shadowing the doctor that had treated him after the crash that had killed his parents and his memories. Dr. Akiyama had been working at the hospital for 30 years and was well respected among the hospital staff. The thing that really did it for Mamoru was the fact that Dr. Akiyama was the man who had made Mamoru want to be a doctor in the first place. He would be overjoyed if it wasn't for one small fact.

Usagi was in Tokyo.

Six years ago, Mamoru was forced to let go of the best thing that ever happened to him. He had always been alone until the little blonde ray of sunshine crashed into his life (literally). Once he had Usagi, he thought he would never have to feel the emptiness he had lived with for eleven years ever again. He actually believed that something good had happened to him. He would never imagined to be the one to break up with her, but in the life of Mamoru Chiba, things never worked out in his favor.

Some cryptic nightmares that told him about his girlfriend's impending doom forced him to break up with Usagi. It had been unexplainably hard at first. Usagi's relentless attempts to change his mind nearly broke him time after time. His heart kept trying to fight his conscience and scoop up the little bunny and kiss her senseless.

Eventually she moved on. It made avoiding her somewhat easier for Mamoru, but it felt like some part of him died that day. Chibi-Usa vanished along with the enemy they were fighting, prompting the senshi to believe the little girl had found her way home and the enemies gave up and moved somewhere else. The nightmares ceased and were replaced by torturous dreams in which Mamoru and Usagi were happily married, breaking him down into painful sobs when he woke up and returned to his lonely life.

The plane skidded to a stop and the passengers began to applaud. Mamoru gazed out the window and took a deep breath.

"Ladies and gentlemen, welcome to Tokyo International Airport. The local time is 4:37 AM. Thank you for flying with United Airlines."

I'll try to have the next update out ASAP. Leave a review and tell me what you think so far! I can't stress how much hearing your thoughts means to me
