[Aether takes a moment to think about it, before a small smile appears on his face.]

I think... that would be Paimon. She's not currently here, but... looks like a small floating fairy. She enjoys eating and coming up with nicknames for people she doesn't like. She doesn't have much strength either...

[The smile on his face widens.]

...But despite that, no matter the danger she's always been by my side, guiding me and doing her best. She's always tried to cheer me up whenever I felt down. That's what heroes do, don't they? Being there for their friends, not abandoning anyone, even if they don't have much power themselves. That's what makes her a hero.

[He laughs softly.]

But if you ever meet her, don't tell her I said that.
