Editing Magicis Puellae in Serena Universi:NPCs (section)

===Hazuki Akiko===
Akiko has been Sakura's rival for years—the two keep getting put into the same classes, and since they get similar grades and have similar fitness levels, it was only natural to compare themselves to one another. Akiko was the one to start viewing Sakura as a rival, but after months of hearing her self-proclaimed rival gloat every time she one-upped Sakura, their competitions just became a fact of life.

When Sakura contracted and found out that Akiko had done so mere days earlier, it didn't help things one bit.

Akiko got captured by a youkai during a battle in episode 4; her current whereabouts are unknown.
