A blue haired youth sat inside an american airport drinking his coffee. He was waiting for his flight to go back home. He hadn't been there in 8 years. Even though it was a 14 hour flight he was very happy. This youth was Nagisa Shiota. He was also feared as the blue reaper. The best assassin ever. They said he was a student of the god of death who disappeared 12 years ago.

*Ding* "First class please began to line up for boarding." As he heard that the blue haired youth smiled and silently said to himself, "Time to go back home."

He got up and walked to the line. He was slim with a masculine appearance. About 180 centimeters tall. He gave off an aura of someone you wouldn't want to mess with.

8 hours on the flight a flight attendant ask Nagisa "Would you like anything to drink.", "Yes can I get a water, please". As he was talking a man behind him snorted in disgust. This was because Nagisa looked poor despite being in the first class area.

"Why are you serving someone poor first you should be serving me." He said in a very rude and arrogant tone. The stewardess looked at him smiled and said, "Sorry sir I'll get you right now". It was obvious she was used to dealing with people like him.

Suddenly four people bursted into the first class with guns. Nagisa saw them and put on a hood and mask. One of them who looked like the leader with an AK-74 yelled at the passengers, "Put all your valuables into the the bag". As he said this he put his gun into one of the passengers and pointed his gun at them.

The leader yelled "I'm going to the cockpit." at his teammates. As they were moving up rows they suddenly got to the person behind Nagisa. He was frightened and Nagisa giggled at him. The man looked at Nagisa with hate not even noticing that he put on a hood. Then they got up to Nagisa and told him to put all the valuables in the bag. Nagisa said " Do I look like I have valuables on me".

This of course angered the man asking him and he said, "You're in first class how can you not have any valuables on you I'll just have to search you". As he said this he began to search Nagisa and found a dagger. "This looks like it can sell for a-lot." the man said. Nagisa said "You can't take that.", the man said " what are you going to do about it".

As he said this Nagisa took the dagger and stabbed it into the man's arm and punched him straight in the jaw knocking him him out. Before the other two men saw this he was already on the move. He took his dagger named Blue fury out of the man and stabbed the closest man near him in the hand that was holding his gun. Then he delivered a kick that knocked him out. When he pulled out his blade there wasn't a speck of blood on it just a radiant blue colored blade.

The other man finally realized what was going on and was about to fire his gun but then felt a sharp pain on his shoulder blade. Blue fury stabbed him and made him drop his gun. At that moment Nagisa appeared behind him and kicked his knee. Looking down on him Nagisa kicked him hitting his head knocking him out as well. Nagisa the took out the Blue fury from his shoulder blade and started heading towards the cockpit.

Before he went in he looked around he silently snuck into the cockpit the leader had his gun to the head of the pilot. He said, "Take the plane to Taiwan". The pilot who was scared for his life nodded and started to fly to Taiwan. At that moment Nagisa snuck behind the leader and brought him to a choke hold knocking him out.

He dragged the leader out of the cockpit and took away their guns and returned to his seat. He took of his hood and mask then asked the stewardess, "Can I get my water right now please I'm very thirsty.", the stewardess looked at him dumbfounded and then grabbed a water and said "Here you are sir." in a bit flustered.

The rest of the flight was very peaceful and when they arrived at the Japan airport Nagisa disappeared. When the pilot came out of the plane the police asked him what happened. The pilot explained that a weird person saved them but he suddenly vanished before they could ask him who he was.

At the front of the airport Nagisa was waiting when a car pulled up it was his mother who looked at him and said "Nagisa you've grown so much. So why are you back?" she said and Nagisa replied with "I told you didn't I, I have finished college and wanted to become a teacher". Even though he was an assassin in America he still went to college. He thought to himself 'I've had enough of being an assassin and settle down and become a teacher'. His mom laughed and then said "I know I just wanted to hear that from you".

Although his mom used to be abusive they now have a friendly relationship after she met Koro-sensei.

She then asked "Did you find any girls while in America"? Nagisa blushed and said "No but I can't stop thinking of one girl I knew". He then thought of a green haired girl. He wasn't sure how she was as he didn't keep in touch with any of his former classmate of class E-3 when he left to America he didn't have time to talk to any of them as he was either on the job or going to college. "Hmm is that so" Nagisa's mother said. "Well whatever let's go home we have a-lot to talk about". "Then let's" he said as he got into the car.
