Reports of summoned people

I've combed through every document and had Sapphire review them multiple times, yet there isn't a single trace of Anna.

"I don't understand. How is this possible?" I mutter, exasperated.

Given the thousands of meticulously detailed reports, it should be impossible for anyone to slip through unnoticed. One of the Basilisk Order's core missions is to keep a vigilant watch over humanity—especially the royal families. Since its inception, the organization has prioritized recording every detail about summoned individuals. That's why Mirayuki was able to gather this wealth of intel so quickly. Every person's blood talent, power rank, and magical attributes are logged in precise detail, along with the circumstances of their lives and deaths—whether celebrated as heroes or discarded as failures, cast off as slaves.

And yet, there is nothing about Anna.

"Did you check every source? Is it possible you missed a profile?" I ask.
