I wonder if there are any plans to make it so that we can get a rat pet, like we get the dog, wolf, raptor, etc... There's already a rodent lure, and it could make a good utility pet. Like maybe it wouldn't help in battle much, biting with a tiny bit of damage, but it could occasionally randomly be holding an item that you would usually forage for in the area you're in. I think that'd be pretty neat.
Edit: As long as I'm posting a comment I may as well say, Loving the game, Hyao! I can tell so much work goes into this.
