When Yugo, Rebecca and Hyoma woke up, they noticed Akira running on the Rainbow Road. "Elder Brother! No!" Yugo shouted. Yugo ran after him first, Rebecca and Hyoma followed. When running on the road full of magical colors, Rebecca said, "Sister Kazane! You knew where your mother is!" Hyoma became shocked that a note was written by his older sister, knowing that his mother was in the Rainbow Realm, a magical place where all of the ancient magic and holy lights existed.

Upon arrival, Akira and his group are amazed at the beauty of the Rainbow Realm filled with magical cities, flower and multi colored spirits that roam freely. Yugo was amazed and said, "This reminds me of my mother's bed time stories about a Princess and the Rainbow Castle."

They walked on a road as they explored a forest full of multicolored trees, rainbow birds and shining lights. Akira, Yugo, Rebecca and Hyoma followed the trail of Kazane's footprint and it led to a train station. They rode on a multicolored train that takes them to a giant castle in the skys and train tracks are made of rainbows.

The Rainbow King appeared before Akira's group and showed them the royal banquet hall filled with the most freshest food and drinks. They found, Kazane feasting alongside the long lost parents of Rebecca and Hyoma. "Mom.... Is that you?" Said Hyoma.

Rebecca sheds some tears and hugs her parents. Akira Sangunji was shedding tears and realizing that Kazane's parents have been trapped in the Rainbow Realm for thousands of years. But the Rainbow King said, "Seeing the parents of your lover injured, I rescued them out of benevolence and saw their offspring grow. I planted a special and dormant message within Kazane and waited for it to awaken it." The Rainbow Queen said, "True Love's first embrace was the only way to awaken the hidden message."

Hyoma was shocked and said, "To this day, I've noticed that our parents left for the Rainbow Realm and now here we are reunited."

Kazane comforted her brother and said, "Hyoma.... You don't have to feel any guilt." The Rainbow King said, "Go Akira and crew. Your people need you."

Akira's group got on the rainbow train and headed back to Earth with the parents of Rebecca, Kazane and Hyoma.

The Rainbow Portal closes as the Rainbow King and Rainbow Queen smiled in peace.
