While they individually explore the city, Anos heads to the Hero Academy saying that he wants to research something. The academy is off-limits to outsiders, but without hesitation, he tries to make his way inside. Eleanor Bianca, a third-year student at the Hero Academy, appears before Anos and says, "You’ll be safe as long as you’re with me" with a mischievous smile. She acts as Anos’ guide inside the academy.
