A bit of deduction to reach the prized item

So how does one find this ultra-secret Rule Scroll anyway? Obviously the people in charge would hide it annoyingly well.

If you were going to configure a shinobi barrier to work as efficiently as possible, you would probably want to make it simple like a circle. If you were going to link that barrier to a powerful ninja scroll, you would want to place that scroll as close to the center point of the bound region as possible.

These design decisions clearly valued efficiency over security, as they would eventually act as key clues to finding this elusive Rule Scroll that Katsuragi has placed her eyes on.

Now that She was aware of the effects of the Rule Scroll, she began experimenting. She approached the Hanzo campus from different positions, taking careful note of when she experienced its effects on her map that Daidouji lent her. After only a couple tests, she was able to draw a perfect circle on it, the center point was none other than the principle's office.

Katsuragi simply waited until nighttime and used her third year shinobi stealth to easily make her way inside. It didn't take much searching to find exactly what she was looking for.
