notices a magic item is actually a human

Kanzaki gritted her teeth, and then felt a chill run down her back.

She was wrong.

The flow of magic power was different from a mere spiritual item.

(It isn't using what is stored within it... It is refining magic power within itself and circulating it. It couldn't be...)

The net of a cube had a few different patterns it could take, but one of them was a cross.

If that cross corresponded to the form of a person...

"Th-this isn't a spiritual item? This is the magician himself who has optimized his physical body into this form!?"

Kanzaki did not just have a massive amount of power. She also carried out delicate analysis and operations, and that was why she had noticed that something was off.
