Thank god Illya is about as gullible as they come. Or at least - she definitely is when it comes to Dreamer-related things. With anything else she might actually gather her courage enough to call someone out, but she knows so little about official Dreamer business that anyone could tell her anything and Illya would most likely believe it..

With this being the prime example. Kozakura just has to nod to that question, and Illya instantly believes the other must truly be strong. After all, who would lie about such a thing? And with such confidence? Clearly you only have that kind of confidence if you are strong.

"W-Wow, I didn't know I was in the presence of someone that amazing.."

She sounds like she's marveling, but then Illya seems to remember manners enough to quickly bow for the other.

"Thank you so much for wanting to help out..! I.. um, I think I feel a little bit calmer already, knowing that there's someone so reliable around to fall back on if anything happens.."

A little calmer, though.

It's still super hard for her to shake off the new Dreamer jitters fully.
