This is just a summary. If you like the summary, then I'll write the story. If not, I'll take this down in three weeks.
Yasu Ito was just an ordinary student, trying to get good grades and get her crush to notice her. But when her sixteenth birthday arrives, a terrible accident occurs, transporting her back to the Senjoku Era and meeting up with Inuyasha and the gang.

But when Kaede hints that a great demoness had the power to bring humans back in time, Yasu leaves the group to their wanderings in search of this mighty lady demon.

But, unknown to Yasu, Naraku watches every step she takes, watching, waiting, for the right time when HER powers awaken.

Yasu Ito, normal schoolgirl? I don't think so.
A little sneak peek:

"Hey, Yasu!" Nyoko winked at her, nudging her with her elbow as she passed Yasu Ito on her way to their lunch table with a tray laden with goodies.

Wondering why her best friend had winked at her, Yasu looked around to find her crush, Hideo Joshuyo right in front of her! "Hideo! Uhmm" Not knowing what to say, Yasu accidentally dropped her pudding on his shoe. "OH! I'm so sorry!"

Grabbing some napkins, Yasu put her tray down to wipe off his shoe, but he stopped her. "Forget about it, Yasu. It really doesn't matter. Here." He said, handing her a blue-wrapped package.

That's it for the sneak peek. If you want to read more about what happens to Yasu, just send reviews!
