It's hard to tell for Chizuru too, honestly. She does know some stuff about animals you're more likely to find in a city, but since she's never really been outside of cities for long stretches of time, she knows much less about deer.

"I don't think it's normal, but.." She pauses. Only briefly, since she knows they're not working with much time here, but Chizuru is not that quick of a thinker. Especially on topics she knows little about. "Maybe it's a special deer. I mean-- um, special things appear here all the time, right..?"

Even if they're usually bad.

"I just hope that it didn't mean to only lead us astray.."

See: the usually bad thing above. Chizuru can't help but wonder about the possibility, even when she really hopes it isn't the truth. The last thing Trench needs is for even the deer to turn out evil in some way.
