Saito Keiko reminisced,
"Of course, all of this was investigated by Muko, and she had wanted to get her hands on this jar more than once.
The first time was thirty years ago, when I was still in high school at Kimyō-kai Women's Academy. During an open exchange class at an art exhibition, I promoted a tea party at our family's hot spring. One of the photos captured this jar.
After seeing it, Muko and her classmates approached me, expressing their wish to work part-time at our hot spring house during summer holiday. But something happened later on, nine people died, and only Muko survived.
The incident had a huge impact on my family's reputation. In a fit of anger, I pressed Muko for answers. She had suffered a lot mentally and eventually told me that she was actually an apprentice Demon Sealing Ninja from the Five Vehicles, and that their group had come for their Genin examination. It was unexpected that so many people would die on their first Demon Sealing trial.
