The place was about to collapse as the boy ran. The boy had long and luscious raven black hair reaching his waist and androgynous face, and due to both most people would most likely mistake him to be a female rather than the male he is. He ran and ran, taking care to avoid any debris falling to himself. His left hand holding a dagger, his right hand tightly clenched.
Then, he found a girl similarly running while avoiding the falling debris. She had dirty blonde hair- almost ashen gray in color, tied into twin-tails. She is holding what seems to be a blood-red jewel shaped like a magatama. The boy then called her.
"Muir! What are you planning to do?"
"Onii-sama! Muir is just about to kill the intruder. Want to come?"
"Sure!"
They continued to run towards the exit of the cave as they found a girl with jade-green hair and pointy hair, a characteristic of the Elfim race, fallen on the ground. As luck would have it, a debris fell straight towards the girl. The boy quickly took action.
"Lily!"
He shouted as he suddenly disappeared and reappeared a few meters away, the girl in hand. It seems the girl regained consciousness just moments before the debris fell, thus being aware of being saved by the boy.
"Master Kamito…"
"Lily, we are about to engage the intruder. You coming?"
"I owe my life to you. I will follow whatever you command."
"Let's go then."
The three then proceeded to the exit, where they found a flame giant with a woman standing on its shoulder. The woman had blazing red hair, as though that they were made of flames and red eyes in a matching color. She looked just a few years older from the boy himself.
The woman then noticed the three and raised her right hand. Following it, the giant swung its arm to the group of three. The three dodged, just barely missing the giant's arm.
"Amdusias!'
The twin-tailed girl shouted. Suddenly, a humanoid creature appeared. It had claws instead of hands and feet and the head of an unicorn. It raised a deafening roar before rushing towards the flaming giant.
The giant engaged the humanoid creature in combat, the creature moving swiftly and dodging the attacks of the giant, its controller failing to notice that the boy had disappeared. Suddenly she felt cold steel against her throat
'So quick!? And I didn't notice it?'
"Surrender quickly or die. If you are willing to surrender and give us information, you will be spared."
The woman raised her hands in defeat and stopped the movements of the giant. After the both of them returned to the ground, the giant disappeared into particles of light, as the humanoid creature.
"Onii-sama, why didn't you kill the girl?"
"We need as much information as we can get. We need to know the state of the world."
"As expected of master Kamito."
"Now then, who are you and what is your purpose?"
Two years after the incident, Greyworth Ciel Mais was attacked in her mansion by three assailants. A year after that, In the Blade Dance, competed two warriors, not backed by any countries, one bearing the name Ren Ashbell and the other Cardinal. Their match in the final round left a deep impression on every single person watching, shooting their fame through the roof, only for them to disappear right after the end of the Blade Dance, never to be seen again.
