Iwena Ozawa

Iwena Ozawa is a tan Japanese woman with a "decent figure" who is the Head Librarian of Azumanga High School and, despite her figure, is not very athletic. Iwena was the first character created for the relaunched Azumanga Who, having not appeared in the original two versions or any of the spinoffs prior to her debut.

As of yet, however, Daniel has not written any lines for her.

Nightmares
Ozawa has had nightmares since First Year began of a cat, a glowbug, and a black lamb. The lamb, as Iwena tells Yomi, radiates a power that no creature should possess...and uses its power to destroy. As the story progresses, her dreams get worse as Susan escalates in her fury toward recent events.

Iwena's final dream occurs the night before the Great Battle: Susan turns directly to her and calls her out, remarking that Ozawa was hiding in plain sight and "you shall be killed like the rest of your soul-drenching species".
