Disclaimer: I don't own anything Inuyasha cuz if I did, I wouldn't be writing this cuz I'd just show it on tv.
It's been five years since Kagome had decided to live in the feudal era with Inuyasha and everyone else. Since they defeated Naraku. Sota has grown into a well-built fifteen year old and he misses his sister very much. We start our story in Sota's school lunchroom with him wondering why she chose that world over theirs. Sota had been told that if anyone asked where his sister was, to tell them her 'chronic illnesses' had forced her to move to a super high tech hospital in America. "What's wrong Sota-chan?" asked Sota's girlfriend Hitomi. "It's nothing Hitomi." Sota sighed. "You're wondering if your sister any better aren't you?" questioned Hitomi "yeah." muttered Sota. "I'm sure your they'll find a cure for your sister's smallpox." Sota sweat dropped "Maybe your mom will let you go see her if you ask." she told him. "Yeah. That's a great idea. Why haven't I ever thought of that." He quickly kissed her on the cheek and dashed off back home.
"Mom. I'm home." Sota called. "Sota? What are you doing home so early?" Mrs. Higurashi replied. "I need to ask you something." "What is it honey?" "Can I go see Kagome?" asked Sota. "Oh. I'm sorry honey. You need a piece of the Shikon Jewel to pass through the eras." "Oh." Sota's expression darkened. "I'll be in my room mom. I'm not gonna go back to school today." "All right."
Sota then remembered something. On the last day Kagome was in this era, she left Sota a piece of the jewel when she said goodbye to him. She told him to take good care of it. Sota looked all through his room from ceiling to floor till all that was left was his old toy chest. He pulled out each of the toys examining all of them. He had almost given up hope when he saw something shimmering at the bottom. He reached down and picked up the Shikon shard he'd been searching for.
Sota dashed to the well as fast as he could without even saying goodbye to his mother. He pushed the doors open and lunged into the well not knowing what he would find,
