Fumetsu no Anata e: Fushi no Tabiji

A mysterious orb is cast into the world and gains form by copying whatever leaves a powerful impression upon it. After becoming a wolf, it meets a nameless boy in an abandoned settlement and begins an endless journey carrying the boy's appearance and final wish.

Now called Fushi, the immortal being encounters March, Parona, Gugu, and Rean, learning language, affection, pain, and sacrifice through them. Every bond helps him grow, but hostile creatures pursue the memories stored inside him, forcing Fushi to preserve what his lost companions entrusted to his heart.
