I guess they could be useful. Is it really okay to just collect them?

[Sure, she's used to picking up items off the floor of Tartarus, but the mine is more likely to actually be owned by someone, and Minako doesn't want to steal]

Ah...are you sure? I don't want to take it if it's something you might need later.

[She doesn't even question the weird healing item. If it's not rancid gravy, then it's fine by her]
