A boy saved a vicious wolf 20,000 years ago and has been with it ever since

The story begins 20,000 years ago in northern Europe. At the time of the glacial period, Koda was the son of a tribal leader. Unfortunately, he fell off a cliff in a collective hunting operation. No news. Everyone thought Koda was dead, but unfortunately, the flood swept him away and saved his life. However, the water sent Koda far from the tribe to the wilderness. In the terrible weather and the threat of extreme lack of resources, Koda embarked on a journey home.
During the journey, Koda met with a lone wolf, who became his traveling companion and named him Alpha. Alpha is the wolf pack's leader, and during his stay with Alpha, Koda learns many skills to survive in the wilderness and is also awakened to his inner wolf nature!
