On the modern-day on Earth, there is an ordinary yet unique boy. His name is Ryuga Kiyotaka. He is from Japan with black hair and a good-looking face. His body is well-build without any excess of muscle. His looks make anyone think he is a model.
Ryuga Kiyotaka is the third year of a distinguished High School. He is very smart and good at athletic too. That makes him become Top 10 cool guys on his school list. But his face rarely showing his emotion. Even so, a lot of girls still have a crush with him.
The boy always calls him 'Doll Prince' because of his emotionless face, but Ryuga never annoyed by their insult. He is very calm and just smiling at anyone. Apart from his good-looking face and his 'Prince' treatments from the girls, he is just ordinary students.
But he has a big secret that no one knows. He is an Elite Hitman who works for his family.
He is an Orphan because his parents died due to an accident when he was 5 years old. He stays on Orphanage and adopted by Kiyotaka Family when he was 8 years old.
Ryuga is very smart and calm in every situation. His 'mature' manner makes his caretaker on Orphanage slightly afraid of him. When he was staying in Orphanage, he spent his day reading books every day. He wants to become a smart boy. He doesn't want to spend his day in Orphanage because no one able to stay near him. His lack of communication skills and his expressionless face make everyone scared of approaching him.
Kiyotaka's family realize his talent and decided to adopt him as their children. He grows up normally and lives with happiness. Kiyotaka Family has a single daughter. Her name is Kosaki Kiyotaka. Kosaki always wanted to have a brother, but her mother can't give birth anymore because of Cancer. Luckily she still able to survive and she is very healthy now.
Kosaki is a very cheerful girl and it was the complete opposite of Ryuga. She always playing with Ryuga even he was slightly bothered by her demeanor. Slowly Ryuga begins to change. He still has a deep wound because of losing his parents, but now he has a family who loves him. He begins the learn emotions like love and compassion from his family. He is angry when someone insults his family. He is sad when his little sister hurts.
Kiyotaka Family is one of the most powerful families in Japan. They control mass media like Television Channel, Newspaper, Magazine, and even the Internet. With his distinguished family background, Ryuga learns how to be a good boy and try not to embarrass his family. But the Kiyotaka family has a big secret that they are an Assassin Family Lineage from the Edo period.
Kiyotaka family also have a lot of enemy because of their influence. They want to control Kiyotaka Family and take advantage of them, but If they are failed to control Kiyotaka Family, they will destroy them. Kiyotaka Residence is very tight to prevent the enemy from sneaking and attack their family members. On the school, Ryuga and Kosaki are protected by School Security.
Kiyotaka's Family decided to adopt him because he has natural talents. Ryuga is very smart, mature and never shows his expression. That makes him will be suitable to become a Hitman because anyone can't figure out his intention.
He hides his identity as an Assasin from his little sister. He doesn't want to make her worry about him. Kosaki never knows about the dark secret of her family and she grows up like a Princess. Thus Ryuga will bear the responsibility and agrees to become the next successor of Kiyotaka's Family Assassin. He wants to become stronger to protect his family and his country to pay his debt to Kiyotaka's Family.
And Ryuga is on his private jet and heading back to Japan. He is just finishing his mission to killing a courier that brings a confidential document to cause havoc on America. Since Japan and America on a mutual relationship, Ryuga was ordered to stop it from happens.
"Haaah...I spent my holiday to complete a mission...But I want to go with my family and have a vacation...."
He was regret that he can't use his holiday with his family, but as an Elite Assassin, Ryuga needs to be professional.
Ryuga is wearing a special Nano-suit and covering his whole body from head to toe. This suit has a lot of functions that will help him to do his mission.No one in this world has this suit because this is the prototypes and the suit was made by Unknown metal from meteorites. Ryuga is very lucky to have a chance to use this suit because he is the Ace of Assassin in Japan. His achievement is flawless and he never failed on his mission. The casualties when he doing his mission are always zero. That makes him able to become [Top-Class Assassin]. This suit is the product of Japan-America research on technology and military asset. Because Assassin's word in the Modern world is rarely heard, his family decides to call him "Special Agents". His mission isn't just to eliminate someone, but he also does delivery a secret document to prevent war, infiltration to rescue hostage, and many dangerous jobs like that.
His right eye is glowing with golden pupil, but his left eye is black. At the glance, he looks to have a heterochromatic, but his golden pupil is because of a High-tech contact lens.
Ryuga wears a High-tech lens to improve his vision. This lens is similar to a powerful AI with a chip planted on his brain to control the lens. He can detect enemy, range, analyst the situation, have thermal sight, night vision, and various functions to support his mission. He using this when he is on the mission, so when he at home, Ryuga won't use this lens.
"Haaah, I want to get home as soon as possible to eat my mother's food."
He sighs twice now because he misses his family so much. He spent two days in America and he tells his little sister that he stays over at his friend's house.
Suddenly his jet shaking because of the storm. He is in the middle of the sea and unfortunately he meets a natural disaster here. He can't control his jet and begin falling.
However, he doesn't show a slightest of panic. He uses his powerful AI to analyze the situation.
[Threat 15%]
[On the middle of the sea = 5%]
[The jet will crush = 5%]
[Storm = 5%]
[Solution]
[Activate Nano Shield]
[Prepare Flight Mode]
[Execute]
The analysis from the AI comes immediately. Even the situation is very dangerous, but the risk for Ryuga is only 15%. That shows how powerful his suit. But suddenly a blinding light comes to block his vision. Normally on the storm, Impossible for sunlight to reach him.
He feels his body was sucked by a powerful force and he almost can't breathe due to the pressure. When the light faded, he opens his eyes and surprised because he is now on plains.
There's no way he can move into plains instantly from the middle of the sea. But before he was able to think about this, Ryuga forgets about his situation. Ryuga is teleported with his jet and his jet crashing on the ground with loud of the explosion until making a slight tremor into the surrounding.
He was dead because of the accident when he teleported.
"Noooooooo....!!!!"
Ohh, he still alive because his Nano-suit makes a Nano-shield to protect him from the explosion.
"Where am I????!!!!!!!!"
He shouted to vent his stress because he was stranded in an unknown place.
