Hamato Yoshi was a young ninjutsu master, the strongest in his clan, living a happy life in Japan with his wife, Tan Shen, and their baby daughter, Miwa. However, his life took a dark turn due to the relentless jealousy of Oroku Saki, a rival determined to prove himself superior to Yoshi and win over Tan Shen's affections.

One night, Saki's rage exploded into violence as he attacked Yoshi's home, setting it ablaze. In the chaos, Tan Shen lost her life, leaving Yoshi devastated with guilt and sorrow. The Hamato clan, blaming him for the tragedy, cast him and Miwa out, shunning them after what should have been a time of mourning.

With a heavy heart, Yoshi wandered through life until he met Aurora while picking up Miwa from daycare. They quickly fell in love, leading them to New York City in search of a fresh start. Four years later, Aurora announced she was pregnant with twins, Leonardo and Raphael. While joy filled their lives, another pregnancy followed, bringing anxiety as the doctor warned about the risks. Despite Yoshi’s concerns, Aurora decided to keep the baby, later giving birth to Michelangelo.

From the beginning, Mikey struggled in the shadow of his older brothers, feeling neglected and alone. As the years passed, he grew into a 16-year-old boy, believing he was utterly isolated. After facing challenges at school, he transferred and met four new friends who embraced him as their little brother. They recognized his hidden spirit and offered him the love and acceptance he had longed for, helping him see that even beyond his family's rejection, a brighter future awaited him filled with true connection.
