He was the last experimental subject.
On the dissection table, the gene serum was about to be injected into his heart. Amid the agony, he heard a voice:
"Child... don't be afraid... I'm here..."
That was Chaos, the ancestor of all beasts, an ultimate being imprisoned beneath an isolated island for thousands of years.
He escaped.
With him came a soul-devouring beast that was forever hungry, a thunderwing beast with broken wings, a rock-armored beast with a shattered shell, and a nine-tailed fox with only one tail...
Every one of them was a discarded "failure." Every one had been sentenced to death by the world.
But in his hands, they became the strongest of companions.
A dark organization hunted him. The four great clans looked down on him. The entire continent wanted him captured.
He didn't care.
Nine contracts, nine shackles. Ten spirit beasts, ten acts of salvation.

Although it is AI, I like reading this kind of beast-controlling novel.
