The world-wide national tournament, Armageddon Combat, was extremely popular among the humans. Every 10 years, this Armageddon Combat would be held and the last one remaining would get riches and be known throughout history. However, this tournament had a little catch to it, winners had the option to pick whether the loser dies or becomes they're servant. Many years later, the tournament decided to give off a little training area, where all likely competitors were able to train and master whatever they wanted, magic, etc.
Now, a young male knowing that his father had been brutally mudered in the tournament joined the tournament to avenge his father, and show all that he would be written in history books.
Sora Okumura(Son of the once-well known champion who had won the 3rd Armageddon Combat but was brutally murdered in the 4th Armageddon Combat, seeking vengance and to show the world his strength, Sora Okumura joined the 5th Armageddon Combat. He is currently 16 years old.)
Ayame Lillyflower(A friend and classmate of Sora Okumura who had fallen for him, Ayame Lillyflower joined the 5th Armageddon Combat to help Sora become the winner, but constantly rather than helping Sora, is the one being saved by Sora. She is currently 15 years old.)
Asuna Gushiken(A female who joined the 5th Armageddon Combat, she is hinted to be some kind of step-sister to Sora Okumura. However, she does have feelings for Sora Okumura, despite them being half-siblings. She is currently 13 years old.)
Kuro Lancelot(A male who joined the 5th Armageddon Combat, he is Sora's teacher. He was quite the coach in karate lessons, which Sora had attented. However, the teacher had told Sora that he will defeat him no matter what when they met, even if it meant killing him. He is currently 32 years old.)
After doing the nessecary exams for a chance to join the Armageddon Combat, Sora Okumura waited at his house. Later, after receiving a mail saying that he was the last Combatant to join, Sora gets ready for the fight.
After class, Sora heads out to the streets with Ayame only to get ambushed by their teacher, Kuro Lancelot. While their teacher aims to defeat Sora, even if it means killing him Sora on the other hand fights, but not to kill. Will this let Sora fall to his death or will this prove that Sora can defeat without killing?
