In the coastal city of Long Bay, a hero clad in green and gold lived. Their name: the Green Youxia. Masked by a star-visor helmet, their identity was unknown, and yet they remained a beacon of hope for the city's citizens, including young Isaac Nofa. Together with his older brother Thomas he lived peacefully, watching the Green Youxia on the local news save the day from the relative comfort of the orphanage they resided in. Until one day, those peaceful days came to a sudden end. The Green Youxia fell to Long Bay's most notorious criminal, Lady Luck, and Isaac's beloved older brother, Thomas, was killed that same day. Devastated and consumed by vengeance, Isaac vows to train his mind, body, and soul to bring Lady Luck to justice. When he finally dons the green and gold once worn by the hero he admired, Isaac believes he knows exactly what he needs to do, but he couldn't be further from the truth. . .
