Your the little sister of Rengoku. About 10-12 years old. And yet your dad is already making you train. At such a young age. As soon as you mastered everything he gave you the sword. Once he saw it didn't glow red he got disappointed "looks like you'll never kill the demon that killed your mother." He said and walked away. You felt anger and annoyance wash over you as Rengoku tried comforting you. "It's fine sis, maybe next time! Besides he was to harsh on you anyway"
