Arashi was born to Tamaro and Fuji in 2009. Arashi means 'storm' in Japan and he was named after his grey-coloured pelt.
When his father, Tamaro, left his family to rule a piece of territory, Fuji was forced to look after her son but days later, Fuji grew very ill and Arashi had to pick herbs and plants for her to get better.
Plant picking, Arashi got into a fight with a stag named Redd. The two fought over an elderberry plant and Redd ended up throwing him to a tree. Arashi weakly tells him that the elderberry plant was for his mother and that she was very ill. Feeling very sorry for the fawn, Redd gave the plant to Arashi but warned him never to came back since he was in a herd's territory.
That night, the leader of Redd's herb, Crash, forced Redd and another deer named Daroo, to find some lush grass by the wolves' territory. Redd and Daroo obeyed and left. Arashi bumped into them again and Redd scolded him for coming back. Arashi exclaimed that he wanted to help them but they told him that it was too dangerous and he was too young to face a wolf.
When Redd and Daroo went to the wolves' territory, a wolf spotted them and there was a huge fight. The wolf killed Daroo and was ready to turn onto Redd. Suddenly, Arashi appeared and started over to the wolf. Covered in blood, Arashi suddenly went into a strange sensation and his eyes turned red all of a sudden. He charged over to the wolf and sent it running away, whelping. Redd was amazed that the fawn used the leader's attack.
Redd followed Arashi back to his grass den and they suddenly saw a dying Fuji. Dying, Fuji told Redd to take her son to his father, who was in Uru Mountains and shortly, she passed away.
Redd and Arashi are now on the journey to Uru Mountains to find Arashi's father, Tamaro.
