Ayu informed her that Junko became a Level 4 from a Level 2 in only two months, and Junko later proved her power by destroying a punching machine. Iruka was impressed by this, and Ayu told her that everyone admires Junko and the facility is meant to raise a Level 5. Hearing this, Iruka thought that she can be like Junko as well.

Iruka later enrolled into Tokiwadai, the same school where Junko goes to.
