In the land of Terra Primordia, nations of humans learned to channel the power of animals to defend themselves from the demonic beasts that ravage the land. One's life as an Anima Spirit Warrior depends on the spirit animal and the capabilities it brings to the user. In Hektor Khion's case, his tortoise spirit and its defensive arts would have led him to a successful life, but his future was destroyed when an incident caused his spirit animal to be damaged, crippling his ability to use advanced techniques. Furthermore, Justin Danaus, the person he thought was his best friend, betrayed him in an attempt to steal his fiancée, Selena Argyris. His friend failed, and the whole affair ended in both Hektor and Selena's death. But this is not the end of their story, as Hektor and Selena woke up in their own bodies eight years ago when they were still childhood friends living in a small riverside village. Knowing what the future had in store, they swore a pact together. They would not allow the mistakes of the past to happen again. Thank you for reading my first novel on Royal Road.
