This was very intriguing to Qixia. Not just this concept of tastes and flavors, but food itself. She drank water, yes, and did eat what nature did provide. She had never had anything that had been made by human, or humanoid, hands before. Qixia had observed this behavior but of course had never partaken in it. That would have meant interacting with them and that... well, she just hadn't been so bold and it had never been necessary nor invited.
What also piqued her interest was Mulciber said he had no functional mouth. It made Qixia look much more closely at her newfound friend. "Does no mouth mean you have no need for sustenance?" That wasn't entirely foreign to her. Spirits had no need of food. Even she never felt truly hungry, but she was certainly no spirit. Since Mulciber was made up of many souls, perhaps he was more akin to a spirit than she.
