Many years before Inuyasha was born, his older sister and Sesshomaru's twin Erika, went missing when she was a young child. When she climbs out of the well in Kagome's era as a young adult, she tells a story of being lost in another land for almost 200 years, and that she needs help to free her friend. Kagome and Inuyasha agree to help, but at what cost?

Prologue

The young Sesshomaru was playing ball with his twin sister, Erika. Their parents were nearby watching them play. Sesshomaru tossed the ball to his sister, but it went past her head. Erika ran after it, her fluff flowing in the wind behind her as she ran. Sesshomaru followed her, not wanting her to go off by herself.

"don't go too far, children." Inukimi said.

The two inu diyoki ran to the edge of the woods. Erika picked up the ball when a rabbit yoki walked out from behind a tree. At least the children thought it was a demon. It wasn't acting like a normal rabbit. Yet even for a demon rabbit, this one was strange. It as a white rabbit with a hat, strange cloths and glasses. He was looking at a shiny gold thing that was on a chain.

"oh my goodness. I'm late!" the rabbit said.

The rabbit traced a circle in the ground and a blue swirling portal appeared. The rabbit jumped in. Erika cautiously went over to the edge and looked in.

"Be careful Erika." Sesshomaru warned.

"I will." Erika said, but the ground under her crumbled and Erika fell in screaming, she held onto a root that was hanging over the edge.

Inutaisho heard his daughter's scream and ran towards her, his hand on Tessaiga's hilt. He arrived at the clearing where the portal was.

"Erika!" Inutaisho called out to his daughter.

"Daddy! Help!" the little dog demon cried out. Inutaisho reached out to his daughter, but she lost her grip on the root and fell into the portal.

"Erika!" Inutaisho called to his daughter, about to dive into the portal.

But he was too late, the portal had already closed with Erika trapped on the other side.

Sesshomaru watched as his father fell to his knees. "daddy, where is Erika?" he asked.

Inutaisho looked at his son. "I don't know." He said, a tear sliding down his face. "but I am going to find her."
